The Church has never added a single teaching of dogmatic value Which was not contained in the original teachings of the Apostles. Where doubts have arisen, she has officially defined the right doctrine, not giving a new doctrine, but clearly expressing the exact significance of the old doctrine. And that is exactly what a teaching Church is for. Meantime the early Christians, by believing in the doctrines of Christ, believed these truths also at least implicitly, though they could quite well have been ignorant of the later terms used to describe them.
