“ It is not certain that they had their origin as a whole in the same age; but the judgment of learned men is that no part of them is older than the second half of the third century. The eighty-five so-called Apostolic Canons have prefixed to them the spurious title: "Ecclesiastical Rules of the Holy Apostles promulgated by Clement High Priest (Pontifex) of the Church of Rome." The origin of these canons is uncertain. They first appear as a collection with the above title in the latter part of the fifth century. How much older some of them may be cannot be determined with certainty. ”
