Papal infallibility

Nature of infallibility

The church teaches that infallibility is a charism entrusted by Christ to the whole church, whereby the Pope, as "head of the college of bishops," enjoys papal infallibility. This charism is the supreme degree of participating in Christ's divine authority, which, in the New Covenant, so as to safeguard the faithful from defection and guarantee the profession of faith, ensures the faithful abide in the truth. The church further teaches that divine assistance is also given to the Pope when he exercises his ordinary Magisterium.

Conditions for teachings being declared infallible

As with all charisms, the church teaches that the charism of papal infallibility must be properly discerned, though only by the Church's leaders. The way to know if something a pope says is infallible or not is to discern if they are ex cathedra teachings. Also considered infallible are the teachings of the whole body of bishops of the Church, especially but not only in an ecumenical council (see Infallibility of the Church).

According to the teaching of the First Vatican Council and Catholic tradition, the conditions required for ex cathedra papal teaching are as follows:

1. the Roman Pontiff
2. speaks ex cathedra,
   1. that is, when, (in the discharge of his office as shepherd and teacher of all Christians, and by virtue of his supreme apostolic authority,)
   2. he defines
   3. a doctrine
      1. concerning faith or morals
      2. to be held by the whole Church

For a teaching by a pope or ecumenical council to be recognized as infallible, the teaching must:

The terminology of a definitive decree usually makes clear that this last condition is fulfilled, as through a formula such as "By the authority of Our Lord Jesus Christ and of the Blessed Apostles Peter and Paul, and by Our own authority, We declare, pronounce and define the doctrine . . . to be revealed by God and as such to be firmly and immutably held by all the faithful," or through an accompanying anathema stating that anyone who deliberately dissents is outside the Catholic Church.

For example, in 1950, with Munificentissimus Deus, Pope Pius XII's infallible definition regarding the Assumption of Mary, there are attached these words:

Hence if anyone, which God forbid, should dare willfully to deny or to call into doubt that which We have defined, let him know that he has fallen away completely from the divine and Catholic Faith.

In July 2005 Pope Benedict XVI stated during an impromptu address to priests in Aosta that: "The Pope is not an oracle; he is infallible in very rare situations, as we know." Pope John XXIII once remarked: "I am only infallible if I speak infallibly but I shall never do that, so I am not infallible." A doctrine proposed by a pope as his own opinion, not solemnly proclaimed as a doctrine of the Church, may be rejected as false, even if it is on a matter of faith and morals, and even more any view he expresses on other matters. A well-known example of a personal opinion on a matter of faith and morals that was taught by a pope but rejected by the Church is the view that Pope John XXII expressed on when the dead can reach the beatific vision. The limitation on the pope's infallibility "on other matters" is frequently illustrated by Cardinal James Gibbons's recounting how the pope mistakenly called him Jibbons.

Catholic theologians in general hold that the canonization of a saint by a pope is infallible teaching that the person canonized is definitely in heaven with God. A decree of canonization commands that the person be venerated by the whole Church as a saint, while beatification merely permits it.

Ex cathedra

"Cathedra" and "sedes" are Latin words for a chair, the symbol of the teacher in the ancient world; the "chair" is still used metaphorically as the office of a university professor, and to the "see" of a bishop (from "sedes"). The pope is said to occupy the "chair of Peter" or the "Holy See," since Catholics hold that, as Peter had a special role among the apostles as the preserver of unity, so the pope as successor of Peter holds the role of spokesman for the whole church among the bishops, the successors of the apostles.

In connection with papal infallibility, the Latin phrase ex cathedra (literally, "from the chair") has been defined as meaning "when, in the exercise of his office as shepherd and teacher of all Christians, in virtue of his supreme apostolic authority, (the Bishop of Rome) defines a doctrine concerning faith or morals to be held by the whole Church."

The response demanded from believers has been characterized as "assent" in the case of ex cathedra declarations of the popes and "due respect" with regard to their other declarations.

Scripture and primacy of Peter

On the basis of Mark 3:16, 9:2, Luke 24:34 and 1 Corinthians 15:5, the Catechism of the Catholic Church describes Peter as holding first place among the apostles. It speaks of Peter as the rock on which, because of Peter's faith, Christ said in Matthew 16:18 he would build his Church, which he declared would be victorious over the powers of death. In Luke 22:32, Jesus gave Peter the mission to keep his faith after every lapse and to strengthen his brothers in it. The Catechism of the Catholic Church sees the power of the keys that Jesus promised to Peter alone in Matthew 16:19 as signifying authority to govern the house of God, that is, the Church, an authority that Jesus after his resurrection confirmed for Peter by instructing him in John 21:15–17 to feed Christ's sheep. The power to bind and loose, conferred on all the apostles jointly and to Peter in particular (Matthew 16:19) is seen in the Catechism of the Catholic Church as authority to absolve sins, to pronounce judgments on doctrine and to make decisions on Church discipline.

Primacy of the Roman pontiff

Doctrine-based religions evolve their theologies over time, and Catholicism is no exception: its theology did not spring instantly and fully formed within the bosom of the earliest Church.

The doctrine of the Primacy of the Roman Bishops, like other Church teachings and institutions, has gone through a development. Thus the establishment of the Primacy recorded in the Gospels has gradually been more clearly recognised and its implications developed. Clear indications of the consciousness of the Primacy of the Roman bishops, and of the recognition of the Primacy by the other churches appear at the end of the 1st century. L. Ott

Pope St. Clement of Rome, c. 99, stated in a letter to the Corinthians: "Indeed you will give joy and gladness to us, if having become obedient to what we have written through the Holy Spirit, you will cut out the unlawful application of your zeal according to the exhortation which we have made in this epistle concerning peace and union." (Denziger §41, emphasis added)

St. Clement of Alexandria wrote on the primacy of Peter c. 200: "the blessed Peter, the chosen, the pre-eminent, the first among the disciples, for whom alone with Himself the Savior paid the tribute..." (Jurgens §436).

The existence of an ecclesiastical hierarchy is emphasized by St. Stephan I, 251, in a letter to the bishop of Antioch: "Therefore did not that famous defender of the Gospel [Novatian] know that there ought to be one bishop in the Catholic Church [of the city of Rome]? It did not lie hidden from him..." (Denziger §45).

St. Julius I, in 341 wrote to the Antiochenes: "Or do you not know that it is the custom to write to us first, and that here what is just is decided?" (Denziger §57a, emphasis added).

Catholicism holds that an understanding among the apostles was written down in what became the scriptures, and rapidly became the living custom of the Church, and that from there, a clearer theology could unfold.

St. Siricius wrote to Himerius in 385: "To your inquiry we do not deny a legal reply, because we, upon whom greater zeal for the Christian religion is incumbent than upon the whole body, out of consideration for our office do not have the liberty to dissimulate, nor to remain silent. We carry the weight of all who are burdened; nay rather the blessed apostle PETER bears these in us, who, as we trust, protects us in all matters of his administration, and guards his heirs" (Denziger §87, emphasis in original).

Many of the Church Fathers spoke of ecumenical councils and the Bishop of Rome as possessing a reliable authority to teach the content of scripture and tradition.

Theological history

Klaus Schatz asserts that "it is impossible to fix a single author or era as the starting point" for the doctrine of papal infallibility. Others such as Brian Tierney have argued that the doctrine of papal infallibility was first proposed by Peter Olivi in the Middle Ages. Schatz and others see the roots of the doctrine as going much further back to the early days of Christianity.

Brian Tierney argued that the 13th-century Franciscan priest Peter Olivi was the first person to attribute infallibility to the pope. Tierney's idea was accepted by August Bernhard Hasler, and by Gregory Lee Jackson, It was rejected by James Heft, and by John V. Kruse. Klaus Schatz says Olivi by no means played the key role assigned to him by Tierney, who failed to acknowledge the work of earlier canonists and theologians, and that the crucial advance in the teaching came only in the 15th century, two centuries after Olivi; and he declares that, "It is impossible to fix a single author or era as the starting point." Ulrich Horst criticized the Tierney view for the same reasons. In his Protestant evaluation of the ecumenical issue of papal infallibility, Mark E. Powell rejects Tierney's theory about 13th-century Olivi, saying that the doctrine of papal infallibility defined at Vatican I had its origins in the 14th century—he refers in particular to Bishop Guido Terreni—and was itself part of a long development of papal claims.

Schatz points to "...the special esteem given to the Roman church community [that] was always associated with fidelity in the faith and preservation of the paradosis (the faith as handed down)." Schatz differentiates between the later doctrine of "infallibility of the papal magisterium" and the Hormisdas formula in 519, which asserted that, "The Roman church has never erred (and will never err)." He emphasizes that Hormisdas formula was not meant to apply so much to, "...individual dogmatic definitions but to the whole of the faith as handed down and the tradition of Peter preserved intact by the Roman Church." Specifically, Schatz argues that the Hormisdas formula does not exclude the possibility of individual popes become heretics because the formula refers "...primarily to the Roman tradition as such and not exclusively to the person of the pope."

Ecumenical councils

The 12th-century Decretum Gratiani contained the declaration by Pope Gregory I (590–604) that the first four ecumenical councils were to be revered "...like the four gospels," because they had been "established by universal consent," and also Gratian's assertion that, "The holy Roman Church imparts authority to the sacred canons but is not bound by them." Commentators on the Decretum, known as the Decretists, generally concluded that a pope could change the disciplinary decrees of the ecumenical councils but was bound by their pronouncements on articles of faith, in which field the authority of a general council was higher than that of an individual pope. Unlike those who propounded the 15th-century conciliarist theories, they understood an ecumenical council as necessarily involving the pope, and meant that the pope plus the other bishops was greater than a pope acting alone.

Middle Ages

Several medieval theologians discussed the infallibility of the pope when defining matters of faith and morals, including Thomas Aquinas.

The Dictatus papae have been attributed to Pope Gregory VII (1073–1085) in the year 1075, but some have argued that they are later than 1087. They assert that no one can judge the pope (Proposition 19) and that "the Roman church has never erred; nor will it err to all eternity, the Scripture bearing witness" (Proposition 22). This is seen as a further step in advancing the idea that "...had been part of church history and debate as far back as 519 when the notion of the Bishop of Rome as the preserver of apostolic truth was set forth in the Formula of Hormisdas."

In the early years of the 14th century, the Franciscan Order found itself in open conflict about the form of poverty to observe, with the Spirituals (so called because associated with the Age of the Spirit that Joachim of Fiore had said would begin in 1260) pitched against the Conventual Franciscans. The Spirituals, who in the 13th century were led by the Joachimist Peter Olivi, adopted extremist positions that eventually discredited the notion of apostolic poverty and led to its condemnation by Pope John XXII. This pope determined to suppress what he considered to be the excesses of the Spirituals, who contended eagerly for the view that Christ and his apostles had possessed absolutely nothing, either separately or jointly. In March 1322, he commissioned experts to examine the idea of poverty based on belief that Christ and the apostles owned nothing. The experts disagreed among themselves, but the majority condemned the idea on the grounds that it would condemn the Church's right to have possessions. The Franciscan chapter held in Perugia in May 1322 declared on the contrary: "To say or assert that Christ, in showing the way of perfection, and the Apostles, in following that way and setting an example to others who wished to lead the perfect life, possessed nothing either severally or in common, either by right of ownership and dominium or by personal right, we corporately and unanimously declare to be not heretical, but true and catholic." One argument used by them was that John XXII's predecessors had declared the absolute poverty of Christ to be an article of faith and that therefore no pope could declare the contrary. Appeal was made in particular to the 14 August 1279 bull Exiit qui seminat, in which Pope Nicholas III stated that renunciation of ownership of all things "...both individually but also in common, for God's sake, is meritorious and holy; Christ, also, showing the way of perfection, taught it by word and confirmed it by example, and the first founders of the Church militant, as they had drawn it from the fountainhead itself, distributed it through the channels of their teaching and life to those wishing to live perfectly."

By the bull Ad conditorem canonum of 8 December of the same year, John XXII, declaring it ridiculous to pretend that every scrap of food given to the friars and eaten by them belonged to the pope, forced them to accept ownership by ending the arrangement according to which all property given to the Franciscans was vested in the Holy See, which granted the friars the mere use of it. He thus demolished the fictitious structure that gave the appearance of absolute poverty to the life of the Franciscan friars, a structure that "...absolved the Franciscans from the moral burden of legal ownership, and enabled them to practise apostolic poverty without the inconvenience of actual poverty." This document was concerned with disciplinary rather than doctrinal matters, but leaders of the Franciscans reacted with insistence on the irreformability of doctrinal papal decrees, with special reference to Exiit. A year later, John XXII issued the short 12 November 1323 bull Cum inter nonnullos, which declared "erroneous and heretical" the doctrine that Christ and his apostles had no possessions whatever.

The next year, the Pope responded to continued criticisms with the bull Quia quorundam of 10 November 1324, He denied the major premise of an argument of his adversaries, "What the Roman pontiffs have once defined in faith and morals with the key of knowledge stands so immutably that it is not permitted to a successor to revoke it." He declared that there was no contradiction between his own statements and those of his predecessors; that it could not be inferred from the words of the 1279 bull that Christ and the apostles had nothing: "indeed, it can be inferred rather that the Gospel life lived by Christ and the Apostles did not exclude some possessions in common, since living 'without property' does not require that those living thus should have nothing in common"; that there were many things in the Franciscan rule "...which Christ neither taught nor confirmed by his example," and that there was neither merit nor truth in pretending Christ and the apostles had no rights in law.

In his book on the First Vatican Council, August Hasler wrote, "John XXII didn't want to hear about his own infallibility. He viewed it as an improper restriction of his rights as a sovereign, and in the bull Qui quorundam (1324) condemned the Franciscan doctrine of papal infallibility as the work of the devil."

Brian Tierney has summed up his view of the part played by John XXII as follows:

Pope John XXII strongly resented the imputation of infallibility to his office – or at any rate to his predecessors. The theory of irreformability proposed by his adversaries was a 'pestiferous doctrine', he declared; and at first he seemed inclined to dismiss the whole idea as 'pernicious audacity'. However, through some uncharacteristic streak of caution or through sheer good luck (or bad luck) the actual terms he used in condemning the Franciscan position left a way open for later theologians to re-formulate the doctrine of infallibility in different language.

In 1330, the Carmelite bishop Guido Terreni described the pope's charism of infallibility in terms very similar to those that the First Vatican Council was to use in 1870.

Post-Counter-Reformation

In the period following the Counter-Reformation the Dominican school of theology at the Roman College of Saint Thomas in Rome, the future Pontifical University of Saint Thomas Aquinas, Angelicum was active in defending the doctrine of Papal infallibility. Vincentius Ferre (+1682), Regent of College of St. Thomas from 1654 to 1672. writes in his De Fide in defense of Papal Infallibility that Christ said "I have prayed for thee, Peter; sufficiently showing that the infallibility was not promised to the Church as apart from (seorsum) the head, but promised to the head, that from him it should be derived to the Church." Dominic Gravina, professor of theology at the College of St. Thomas in Rome wrote concerning Papal infallibility: "To the Pontiff, as one (person) and alone, it was given to be te head," and again, "The Roman Pontiff for the time being is one, therefore he alone has infallibility." Vincenzo Maria Gatti, also a professor of theology at the College of st. Thomas defended papal infallibility says of Christ's words "I have prayed for thee," etc., that "indefectibity is promised to Peter apart from (seorsum) the Church, or from the Apostles; but it is not promised to the Apostles, or to the Church. apart (seorsum) the head, or with the head," adding "Therefore Peter, even apart from (seorsum) the Church, is infallible."

Dogmatic definition of 1870

The infallibility of the pope was formally defined in 1870, although the tradition behind this view goes back much further. In the conclusion of the fourth chapter of its Dogmatic Constitution on the Church Pastor aeternus, the First Vatican Council declared the following, with bishops Aloisio Riccio and Edward Fitzgerald dissenting:

We teach and define that it is a dogma Divinely revealed that the Roman pontiff when he speaks ex cathedra, that is when in discharge of the office of pastor and doctor of all Christians, by virtue of his supreme Apostolic authority, he defines a doctrine regarding faith or morals to be held by the universal Church, by the Divine assistance promised to him in Blessed Peter, is possessed of that infallibility with which the Divine Redeemer willed that his Church should be endowed in defining doctrine regarding faith or morals, and that therefore such definitions of the Roman pontiff are of themselves and not from the consent of the Church irreformable.

According to Catholic theology, this is an infallible dogmatic definition by an ecumenical council. Because the 1870 definition is not seen by Catholics as a creation of the Church, but as the dogmatic revelation of a truth about the papal magisterium, papal teachings made prior to the 1870 proclamation can, if they meet the criteria set out in the dogmatic definition, be considered infallible. Ineffabilis Deus is an example of this.

A British Prime Minister, William Ewart Gladstone, publicly attacked Vatican I, stating that Roman Catholics had "...forfeited their moral and mental freedom." He published a pamphlet called The Vatican Decrees in their Bearing on Civil Allegiance in which he described the Catholic Church as "an Asian monarchy: nothing but one giddy height of despotism, and one dead level of religious subservience." He further claimed that the Pope wanted to destroy the rule of law and replace it with arbitrary tyranny, and then to hide these "...crimes against liberty beneath a suffocating cloud of incense." Cardinal Newman famously responded with his Letter to the Duke of Norfolk. In the letter he argues that conscience, which is supreme, is not in conflict with papal infallibility—though he toasts, "I shall drink to the Pope if you please—still, to conscience first and to the Pope afterwards." He stated later that, "The Vatican Council left the Pope just as it found him," satisfied that the definition was very moderate, and specific in regards to what specifically can be declared as infallible.

Lumen gentium

The dogmatic constitution Lumen gentium of the Second Vatican Ecumenical Council, which was also a document on the Church itself, explicitly reaffirmed the definition of papal infallibility, so as to avoid any doubts, expressing this in the following words:

This Sacred Council, following closely in the footsteps of the First Vatican Council, with that Council teaches and declares that Jesus Christ, the eternal Shepherd, established His holy Church, having sent forth the apostles as He Himself had been sent by the Father;(136) and He willed that their successors, namely the bishops, should be shepherds in His Church even to the consummation of the world. And in order that the episcopate itself might be one and undivided, He placed Blessed Peter over the other apostles, and instituted in him a permanent and visible source and foundation of unity of faith and communion. And all this teaching about the institution, the perpetuity, the meaning and reason for the sacred primacy of the Roman Pontiff and of his infallible magisterium, this Sacred Council again proposes to be firmly believed by all the faithful.

Instances of infallible declarations

The Catholic Church does not teach that the pope is infallible in everything he says; official invocation of papal infallibility is – apart from canonizations of saints – extremely rare.

Catholic theologians agree that both Pope Pius IX's 1854 definition of the dogma of the Immaculate Conception of Mary and Pope Pius XII's 1950 definition of the dogma of the Assumption of Mary are instances of papal infallibility, a fact confirmed by the Church's magisterium. However, theologians disagree about what other documents qualify.

Regarding historical papal documents, Catholic theologian and church historian Klaus Schatz made a thorough study, published in 1985, that identified the following list of ex cathedra documents (see Creative Fidelity: Weighing and Interpreting Documents of the Magisterium, by Francis A. Sullivan, chapter 6):

1. Tome to Flavian, Pope Leo I, 449, on the two natures in Christ, received by the Council of Chalcedon;
2. Letter of Pope Agatho, 680, on the two wills of Christ, received by the Third Council of Constantinople;
3. Benedictus Deus, Pope Benedict XII, 1336, on the beatific vision of the just after death rather than only just prior to final judgment;
4. Cum occasione, Pope Innocent X, 1653, condemning five propositions of Jansen as heretical;
5. Auctorem fidei, Pope Pius VI, 1794, condemning seven Jansenist propositions of the Synod of Pistoia as heretical;
6. Ineffabilis Deus, Pope Pius IX, 1854, defining the Immaculate Conception;
7. Munificentissimus Deus, Pope Pius XII, 1950, defining the Assumption of Mary.

There is no complete list of papal statements considered infallible. A 1998 commentary on Ad Tuendam Fidem issued by the Congregation for the Doctrine of the Faith published on L'Osservatore Romano in July 1998 listed a number of instances of infallible pronouncements by popes and by ecumenical councils, but explicitly stated (at no. 11) that this was not meant to be a complete list.

One of the documents mentioned is Pope John Paul II's apostolic letter Ordinatio Sacerdotalis on reserving priestly ordination to men alone, which the Congregation earlier stated to be infallible, although not taught ex cathedra (i.e., although not a teaching of the extraordinary magisterium), clarifying that the content of this letter has been taught infallibly by the ordinary and universal magisterium. This was confirmed in a commentary by the same Congregation and in commentaries by Cardinals Joseph Ratzinger and Tarcisio Bertone. Many eminent theologians dispute that this is truly infallible, including Nicholas Lash, an ex-priest and Emeritus Professor of Divinity at the University of Cambridge. The Catholic Theological Society of America in a report, "Tradition and the Ordination of Women", concluded that Ordinatio Sacerdotalis is mistaken with regard to its claims on the authority of this teaching and its grounds in Tradition.

As well as popes, ecumenical councils have made pronouncements that the Church considers infallible.

Denial by Catholics

Examples of Catholics who before the First Vatican Council disbelieved in papal infallibility are French abbé François-Philippe Mesenguy (1677–1763), who wrote a catechism denying the infallibility of the pope, and the German Felix Blau (1754–1798), who as professor at the University of Mainz criticized infallibility.

In 1822, Bishop Baine declared: "In England and Ireland I do not believe that any Catholic maintains the Infallibility of the Pope."

A 1989–1992 survey of young people of the 15 to 25 age group (81% of whom were Catholics, 84% were younger than 19, and 62% were male) chiefly from the United States, but also from Austria, Canada, Ecuador, France, Ireland, Italy, Japan, Korea, Peru, Spain and Switzerland, found that 36.9% affirmed that, "The Pope has the authority to speak with infallibility," 36.9% (exactly the same proportion) denied it, and 26.2% said they didn't know.

In addition, before 1870, belief in papal infallibility was not a defined requirement of Catholic faith. The Church therefore accepted the oath required of Catholics in Ireland from 1793 for admittance to certain positions and stated that, "It is not an article of the Catholic Faith, neither am I thereby required to believe or profess that the Pope is infallible." The Irish bishops repeated their acceptance in a 25 January 1826 pastoral address to the Catholic clergy and laity in Ireland, stating: "The Catholics of Ireland not only do not believe, but they declare upon oath ... that it is not an article of the Catholic faith, neither are they required to believe, that the Pope is infallible, and that they do not hold themselves 'bound to obey any order in its own nature immoral', though the Pope or any ecclesiastical power should issue or direct such an order; but, on the contrary, that it would be sinful in them to pay any respect or obedience thereto."

In the Declaration and Protestation signed by the English Catholic Dissenters in 1789, the year of the French Revolution, the signatories state:

We have also been accused of holding, as a Principle of our Religion, That implicit Obedience is due from us to the Orders and Decrees of Popes and General Councils; and that therefore if the Pope, or any General Council, should, for the Good of the Church, command us to take up Arms against the Government, or by any means to subvert the Laws and Liberties of this Country, or to exterminate Persons of a different Persuasion from us, we (it is asserted by our Accusers) hold ourselves bound to obey such Orders or Decrees, on pain of eternal Fire:

Whereas we positively deny, That we owe any such Obedience to the Pope and General Council, or to either of them; and we believe that no Act that is in itself immoral or dishonest can ever be justified by or under Colour that it is done either for the Good of the Church, or in Obedience to any ecclesiastical Power whatever. We acknowledge no Infallibility in the Pope, and we neither apprehend nor believe, that our Disobedience to any such Orders or Decrees (should any such be given or made) could subject us to any Punishment whatever.

Sparrow Simpson remarked that, "All works reprinted since 1870 have been altered into conformity with Vatican ideas. In some cases the process of reducing to conformity was begun at an earlier date. It is therefore with works printed before 1870 that we are now concerned." He therefore cites editions prior to that date.

In his theological works published in 1829, Professor Delahogue asserted that the doctrine that the Roman Pontiff, even when he speaks ex cathedra, is possessed of the gift of inerrancy or is superior to General Councils may be denied without loss of faith or risk of heresy or schism.

In his 1829 study On the Church, Delahogue stated: "Ultramontane theologians attribute infallibility to the Bishop of Rome considered in this aspect and when he speaks, as the saying is, ex cathedra. This is denied by others, in particular by Gallicans."

The 1830 edition of Berrington and Kirk's Faith of Catholics stated: "Papal definitions or decrees, in whatever form pronounced, taken exclusively from a General Council or acceptance of the Church, oblige no one under pain of heresy to an interior assent."

The 1860 edition of Keenan's Catechism in use in Catholic schools in England, Scotland and Wales attributed to Protestants the idea that Catholics were obliged to believe in papal infallibility:

(Q.) Must not Catholics believe the Pope himself to be infallible?
(A.) This is a Protestant invention: it is no article of the Catholic faith: no decision of his can oblige under pain of heresy, unless it be received and enforced by the teaching body, that is by the bishops of the Church.

Sparrow Simpson quotes also from the 1895 revision:

(Q.) But some Catholics before the Vatican Council denied the Infallibility of the Pope, which was also formerly impugned in this very Catechism.

(A.) Yes; but they did so under the usual reservation – 'in so far as they could then grasp the mind of the Church, and subject to her future definitions' ...

In 1861, Professor Murray of the major Irish Catholic seminary of Maynooth wrote that those who genuinely deny the infallibility of the pope "are by no means or only in the least degree (unless indeed some other ground be shown) to be considered alien from the Catholic Faith."

Critical works such as Roman Catholic Opposition to Papal Infallibility (1909) by W. J. Sparrow Simpson have thus documented opposition to the definition of the dogma during the First Vatican Council even by those who believed in its teaching but felt that defining it was not opportune.

Following the 1869–1870 First Vatican Council, dissent arose among a few Catholics, almost exclusively German, Austrian, and Swiss, over the definition of papal infallibility. The dissenters, while holding the General Councils of the Church infallible, were unwilling to accept the dogma of papal infallibility, and thus a schism arose between them and the Church, resulting in the formation of communities in schism with Rome, which became known as the Old Catholic Churches. The vast majority of Catholics accepted the definition.

Before the First Vatican Council, John Henry Newman, while personally convinced, as a matter of theological opinion, of papal infallibility, opposed its definition as dogma, fearing that the definition might be expressed in over-broad terms open to misunderstanding. He was pleased with the moderate tone of the actual definition, which "affirmed the pope's infallibility only within a strictly limited province: the doctrine of faith and morals initially given to the apostolic Church and handed down in Scripture and tradition."

A few present-day Catholics, such as Hans Küng, author of Infallible? An Inquiry, and historian Garry Wills, author of Papal Sin, refuse to accept papal infallibility as a matter of faith. Küng has been sanctioned by the Church by being excluded from teaching Catholic theology. Brian Tierney agrees with Küng, whom he cites, and concludes: "There is no convincing evidence that papal infallibility formed any part of the theological or canonical tradition of the church before the thirteenth century; the doctrine was invented in the first place by a few dissident Franciscans because it suited their convenience to invent it; eventually, but only after much initial reluctance, it was accepted by the papacy because it suited the convenience of the popes to accept it." Garth Hallett, "drawing on a previous study of Wittgenstein's treatment of word meaning," argued that the dogma of infallibility is neither true nor false but meaningless; in practice, he claims, the dogma seems to have no practical use and to have succumbed to the sense that it is irrelevant.

Catholic priest August Bernhard Hasler (d. 3 July 1980) wrote a detailed analysis of the First Vatican Council, presenting the passage of the infallibility definition as orchestrated. Roger O'Toole described Hasler's work as follows:

1. It weakens or demolishes the claim that papal infallibility was already a universally accepted truth, and that its formal definition merely made de jure what had long been acknowledged de facto.
2. It emphasizes the extent of resistance to the definition, particularly in France and Germany.
3. It clarifies the 'inopportunist' position as largely a polite fiction and notes how it was used by Infallibilists to trivialize the nature of the opposition to papal claims.
4. It indicates the extent to which 'spontaneous popular demand' for the definition was, in fact, carefully orchestrated.
5. It underlines the personal involvement of the pope who, despite his coy disclaimers, appears as the prime mover and driving force behind the Infallibilist campaign.
6. It details the lengths to which the papacy was prepared to go in wringing formal 'submissions' from the minority even after their defeat in the Council.
7. It offers insight into the ideological basis of the dogma in European political conservatism, monarchism and counter-revolution.
8. It establishes the doctrine as a key contributing element in the present 'crisis' of the Roman Catholic Church.

Mark E. Powell, in his examination of the topic from a Protestant point of view, writes: "August Hasler portrays Pius IX as an uneducated, abusive megalomaniac, and Vatican I as a council that was not free. Hasler, though, is engaged in heated polemic and obviously exaggerates his picture of Pius IX. Accounts like Hasler's, which paint Pius IX and Vatican I in the most negative terms, are adequately refuted by the testimony of participants at Vatican I."

Objections

Those opposed to papal infallibility such as Geisler and MacKenzie say that it is contrary to Scripture and to the teaching of the early Church.

Eastern Orthodoxy

The dogma of papal infallibility is rejected by Eastern Orthodoxy. Orthodox Christians hold that the Holy Spirit will not allow the whole Body of Orthodox Christians to fall into error but leave open the question of how this will be ensured in any specific case. Eastern Orthodoxy considers that the first seven ecumenical councils were infallible as accurate witnesses to the truth of the gospel, not so much on account of their institutional structure as on account of their reception by the Christian faithful.

Additionally, Orthodox Christians do not believe that any individual bishop is infallible or that the idea of papal infallibility was taught during the first centuries of Christianity. Orthodox historians often point to the condemnation of Pope Honorius I as a heretic by the Sixth Ecumenical council as a significant indication. However, it is debated whether Honorius' letter to Sergius met (in retrospect) the criteria set forth at Vatican I. Other Orthodox scholars argue that past papal statements that appear to meet the conditions set forth at Vatican I for infallible status presented teachings in faith and morals are now acknowledged as problematic.

Anglican churches

The Church of England and its sister churches in the Anglican Communion reject papal infallibility, a rejection given expression in the Thirty-Nine Articles of Religion (1571):

XIX. Of the Church. The visible Church of Christ is a congregation of faithful men, in which the pure Word of God is preached, and the Sacraments be duly ministered according to Christ's ordinance, in all those things that of necessity are requisite to the same. As the Church of Jerusalem, Alexandria, and Antioch, have erred, so also the Church of Rome hath erred, not only in their living and manner of Ceremonies, but also in matters of Faith.

XXI. Of the Authority of General Councils. General Councils may not be gathered together without the commandment and will of Princes. And when they be gathered together, (forasmuch as they be an assembly of men, whereof all be not governed with the Spirit and Word of God,) they may err, and sometimes have erred, even in things pertaining unto God. Wherefore things ordained by them as necessary to salvation have neither strength nor authority, unless it may be declared that they be taken out of holy Scripture.

Methodism

John Wesley amended the Anglican Articles of Religion for use by Methodists, particularly those in America. The Methodist Articles omit the express provisions in the Anglican articles concerning the errors of the Church of Rome and the authority of councils, but retain Article V, which implicitly pertains to the Roman Catholic idea of papal authority as capable of defining articles of faith on matters not clearly derived from Scripture:

V. Of the Sufficiency of the Holy Scriptures for Salvation. The Holy Scripture containeth all things necessary to salvation; so that whatsoever is not read therein, nor may be proved thereby, is not to be required of any man that it should be believed as an article of faith, or be thought requisite or necessary to salvation...

Reformed churches

Presbyterian and Reformed churches reject papal infallibility. The Westminster Confession of Faith, which was intended in 1646 to replace the Thirty-Nine Articles, goes so far as to label the Roman pontiff "Antichrist"; it contains the following statements:

(Chapter one) IX. The infallible rule of interpretation of Scripture is the Scripture itself: and therefore, when there is a question about the true and full sense of any Scripture (which is not manifold, but one), it must be searched and known by other places that speak more clearly.

(Chapter one) X. The supreme judge by which all controversies of religion are to be determined, and all decrees of councils, opinions of ancient writers, doctrines of men, and private spirits, are to be examined, and in whose sentence we are to rest, can be no other but the Holy Spirit speaking in the Scripture.

(Chapter Twenty-Five) VI. There is no other head of the Church but the Lord Jesus Christ. Nor can the Pope of Rome, in any sense, be head thereof; but is that Antichrist, that man of sin, and son of perdition, that exalts himself, in the Church, against Christ and all that is called God.

Evangelical churches

Evangelical churches do not believe in papal infallibility for reasons similar to those of Methodist and Reformed Christians. Evangelicals believe that the Bible alone is infallible or inerrant. Most evangelical churches and ministries have statements of doctrine that explicitly say that the Bible, composed of the Hebrew Scriptures and the New Testament, is the sole rule for faith and practice. Most of these statements, however, are articles of faith that evangelicals affirm in a positive way, and contain no reference to the papacy or other beliefs that are not part of evangelical doctrine.

According to Raffaele De Cesare:

The first idea of convening an Ecumenical Council in Rome to elevate the temporal power into a dogma, originated in the third centenary of the Council of Trent, which took place in that city in December, 1863, and was attended by a number of Austrian and Hungarian prelates.

However, following the Austro-Prussian War, Austria had recognized the Kingdom of Italy. Consequently, because of this and other substantial political changes: "The Civiltà Cattolica suggested that the papal infallibility should be substituted for the dogma of temporal power..."

Moritz Busch's Bismarck: Some secret pages of his history, Vol. II, Macmillan (1898) contains the following entry for 3 March 1872 in pp. 43–44.

Bucher brings me from upstairs instructions and material for a Rome despatch for the Kölnische Zeitung. It runs as follows: "Rumours have already been circulated on various occasions to the effect that the Pope intends to leave Rome. According to the latest of these the Council, which was adjourned in the summer, will be reopened at another place, some persons mentioning Malta and others Trient. [...] Doubtless the main object of this gathering will be to elicit from the assembled fathers a strong declaration in favour of the necessity of the Temporal Power. Obviously a secondary object of this Parliament of Bishops, convoked away from Rome, would be to demonstrate to Europe that the Vatican does not enjoy the necessary liberty, although the Act of Guarantee proves that the Italian Government, in its desire for reconciliation and its readiness to meet the wishes of the Curia, has actually done everything that lies in its power."

Bismarck's reaction

According to F.B.M. Hollyday, Chancellor Otto von Bismarck feared that Pius IX and future popes would use the infallibility dogma as a weapon for promoting a potential "papal desire for international political hegemony":

Bismarck's attention was also riveted by fear of what he believed to be the desire of the international Catholic church to control national Germany by means of the papal claim of infallibility, announced in 1870. If, as has been argued, there was no papal desire for international political hegemony and Bismarck's resistance to it may be described as shadowboxing, many statesmen of the time were of the chancellor's persuasion. The result was the Kulturkampf, which, with its largely Prussian measures, complemented by similar actions in several other German states, sought to curb the clerical danger by legislation restricting the Catholic church's political power. [F.B.M. Hollyday, Bismarck, (Great Lives Observed, Prentice-Hall (1970) p. 6]

One example of the Catholic church's political actions, to add to the many that had occurred down the centuries, had already occurred in Italy on 29 February 1868, when the Sacred Penitentiary issued the decree Non Expedit, which declared that a Catholic should be "neither elector nor elected" in the Kingdom of Italy. The principal motive of this decree was that the oath taken by deputies might be interpreted as an approval of the spoliation of the Holy See, as Pius IX declared in an audience of 11 October 1874. Only in 1888 was the decree declared to be an absolute prohibition rather than an admonition meant for one particular occasion.

In 1872 Bismarck attempted to reach an understanding with other European governments, whereby future papal elections would be manipulated. He proposed that European governments should agree beforehand on unsuitable papal candidates, and then instruct their national cardinals to vote in the appropriate manner. This plan was circulated in ["Bismarck's confidential diplomatic circular to German representatives abroad," Berlin, 14 May 1872, as translated in: F.B.M. Hollyday, Bismarck, (Great Lives Observed, Prentice-Hall (1970) pp. 42–44], in which Bismarck wrote:

The concordats already concluded at the beginning of the century produced direct and, to some extent, intimate relations between the Pope and governments, but, above all, the Vatican Council, and both its most important statements about infallibility and about the jurisdiction of the Pope, also entirely altered his position in relation to the governments. Their interest in the election of the Pope increased to the greatest degree--but with that their right to concern themselves with it was also given a much firmer basis. For, by these decisions, the Pope has come into the position of assuming episcopal rights in every single diocese and of substituting papal for episcopal power. Episcopal has merged into papal jurisdiction; the Pope no longer exercises, as heretofore, individual stipulated special privileges, but the entire plenitude of episcopal rights rests in his hands. In principle, he has taken the place of each individual bishop, and, in practice, at every single moment, it is up to him alone to put himself in the former's position in relation to the governments. Further the bishops are only his tools, his officials without responsibility. In relation to the governments, they have become officials of a foreign sovereign, and, to be sure, a sovereign who, by virtue of his infallibility, is a completely absolute one--more so than any absolute monarch in the world. Before the governments concede such a position to a new Pope and grant him the exercise of such rights, they must ask themselves whether the election and person chosen offer the guarantees they are justified in demanding against the misuse of such rights. [p. 43]

When this scheme did not materialize, Bismarck accelerated his Kulturkampf against the Catholic Church in Germany.

Non-Christian equivalents

Islam stated the infallibility of the prophets and of tradition, but did not point a particular authority in present time as infallible. However, concepts of infallibility developed in some contemporary fundamentalist Islamic movements. In Judaism, the doctrine of Da'as Torah has grown some ideas regarding the infallibility of leading Ultra-Orthodox rabbis. These are far from being consented by all or even most of the Orthodox Jews, let alone others.
