The early Church did not admit that the Pope was infallible, nor did any Pope before Pius EX. claim such a privilege.

The doctrine is contained in Christ’s words to St. Peter, and the early Church was well aware of the fact. TertuUian, about the year 200 A.D. wrote concerning St. Paul’s rebuke to St. Peter, “If Peter was rebuked by Paul, it was certainly for a fault in conduct, not in teaching.” St. Cyprian, about 256, wrote of the See of Rome, “Would heretics dare to come to the very seat of Peter whence Apostolic faith is derived and whither no errors can come.” St. Augustine in the 4th century gives us the famous expression, “Rome has spoken; the cause is finished.” The early Popes had little need to insist often upon a doctrine which was denied by none of the faithful. The Council of Ephesus in 431 thus expressed its firm convictions, “No one doubts, nay it is known to all ages, that Peter, the chief and head of the Apostles, the pillar of the faith and foundation of the Catholic Church, received the keys of the kingdom from Our Lord Jesus Christ …. Peter, who even to these our own days, and always in his successors, lives and exercises his authority.” In 451 Pope Leo wrote his decision to the Bishops of the Church assembled at Chalcedon, and when the letter was read all cried out, “Peter has spoken through Leo.”
