The simple have no faith implied in that of the learned, except in so far as the latter adhere to the Divine teaching. Hence the Apostle says (1 Corinthians 4:16): “Be ye followers of me, as I also am of Christ.” Hence it is not human knowledge, but the Divine truth that is the rule of faith: and if any of the learned stray from this rule, he does not harm the faith of the simple ones, who think that the learned believe aright; unless the simple hold obstinately to their individual errors, against the faith of the universal Church, which cannot err, since Our Lord said (Luke 22:32): “I have prayed for thee,” Peter, “that thy faith fail not.”
