Roman Catholic Quotes Regarding the Pope
It would of course be a monstrous anachronism were we to attribute a belief in papal infallibility to Ante-Nicene Fathers.
[Addis and Arnold, Catholic Dictionary, The Catholic Publication Society, 1887, page 674]
The Pope in himself is subject to error like other men; his infallibility comes from the Spirit of God, which on certain occasions protects him from error in faith and morals. He has no infallibility in merely historical or scientific questions. Even in matters of faith and morals he has no inspiriation, and must use the same means of theological inquiry open to other men. He may err as a private doctor; nor is any immunity from error granted to books which he may write and publish. Even when he speaks with Apostolic authority he may err.
[Addis and Arnold, Catholic Dictionary, The Catholic Publication Society, 1887, page 677]
The number of texts infallibly interpreted by the Church is small; it has been estimated indeed that the total of such texts is under twenty.
[Catholic Commentary, page 59]
It would be an enormous mistake to suppose that the Pope is considered infallible, even on matters of faith, in his ordinary conversation; nor is he believed to be so in preaching; nor necessarily in his writings concerning matters of religion.
[George M. Searle, Plain Facts, Paulist Press, New York, page 38]
A pope is not infallible in proceedings such as those of Honorius who contributed unintentionally to the increase of heresy.
