The Church has authority from God to teach regarding faith and morals, and in her teaching she is preserved from error by the special guidance of the Holy Ghost.
The prerogative of infallibility is clearly deduced from the attributes of the Church: the Church is One, Holy, Catholic, and Apostolic. Preaching the same creed everywhere and at all times; teaching holiness and truth, she is, of course, essentially unerring in her doctrine; for what is one, holy or unchangeable must be infallibly true.
That the Church was infallible in the Apostolic age is denied by no Christian. We never question the truth of the Apostles' declarations;(See Gal. 4:14; 1Thess. 2: 13.) they were, in fact, the only authority in the Church for the first century. The New Testament was not completed till the close of the first century. There is no just ground for denying to the Apostolic teachers of the twenty-first century in which we live a prerogative clearly possessed by those of the first, especially as the Divine Word nowhere intimates that this unerring guidance was to die with the Apostles. On the contrary, as the Apostles transmitted to their successors their power to preach, to baptize, to ordain, to confirm, etc., they must also have handed down to them the no less essential gift of infallibility.
