Satis cognitum is an encyclical of Pope Leo XIII dated 29 June 1896 on the unity of the Church, and some heresies of his time.
The document contains an extensive articulation of and apologia for Catholic ecclesiology as it relates to the Church's unity, one of the four marks of the Church according to the Niceno-Constantinopolitan Creed, which professes belief in "one, holy, catholic, and apostolic Church." In the second half of the text, Pope Leo strongly defends the primacy of the Roman Pontiff as taught at the First Vatican Council as a corollary of the Church's unity. The encyclical concludes with an appeal to non-Catholic Christians and others for reunion with the Catholic Church.
