Many, probably most, commentators have considered this the most important and most interesting of all the Nicene canons, and a whole library of works has been written upon it, some of the works asserting and some denying what are commonly called the Papal claims. If any one wishes to see a list of the most famous of these works he will find it in Phillips’s Kirchenrecht (Bd. ii. S. 35). I shall reserve what I have to say upon this subject to the notes on a canon which seems really to deal with it, confining myself here to an elucidation of the words found in the canon before us.
