It is very probable that the diocese of Acqui was erected at the end of the fourth century, about the same time, it would appear, as the dioceses of Novara, Turin, Ivrea, Aosta and perhaps, Asti and Alba.
The first undoubted bishop of Acqui is Ditarius. A tablet found in 1753 in the church of St. Peter, informs us that Ditarius, the bishop, died on the 25 January, 488, in the Consulate of Dinamias and Syphidius. Popular tradition gives Deusdedit, Andreas Severus Masimus, and, earliest of all, Majorinus, as bishops prior to him.
Majorinus probably lived either at the end of the fourth, or in the beginning of the fifth, century. The name was very common in the third, fourth, and fifth centuries. Augustine of Hippo (De Haereses, I, 69) speaks of two bishops of this name; two others appear as signers of the Letter of the Synod of Carthage to Pope Innocent I (401-417) against Pelagius (Ep. St. Aug., II, 90). Veneration was offered to the saint from time immemorial by the church in Acqui, shown by his statues and relics. This veneration, however, has ceased since a decree of the Congregation of Rites (8 April 1628) prohibited the veneration of saints whose sanctity had not been declared by the Holy See.
In the list of the bishops of Acqui, Saint Guido (1034–70) was of the Counts of Acquesana under whose government the cathedral was erected. He is the patron saint of Acqui.
