The Latin text of this difficult but important clause is, “Ad hanc enim ecclesiam propter potiorem principalitatem necesse est omnem convenire ecclesiam.” Both the text and meaning have here given rise to much discussion. It is impossible to say with certainty of what words in the Greek original “potiorem principalitatem” may be the translation. We are far from sure that the rendering given above is correct, but we have been unable to think of anything better. [A most extraordinary confession. It would be hard to find a worse; but take the following from a candid Roman Catholic, which is better and more literal: “For to this Church, on account of more potent principality, it is necessary that every Church (that is, those who are on every side faithful) resort; in which Church ever, by those who are on every side, has been preserved that tradition which is from the apostles.” (Berington and Kirk, vol. i. p. 252.) Here it is obvious that the faith was kept at Rome, by those who resort there from all quarters. She was a mirror of the Catholic World, owing here orthodoxy to them; not the Sun, dispensing her own light to others, but the glass bringing their rays into a focus. See note at end of book iii.] A discussion of the subject may be seen in chap. xii. of Dr. Wordsworth’s St. Hippolytus and the Church of Rome.
