The words for which I have given the original Greek, are not mentioned by Canon Bright in his Article on St. Cyril in Smith and Wace’s Dictionary of Christian Biography; nor by Ffoulkes in his article on the Council of Ephesus in Smith and Cheetham’s Dictionary of Christian Antiquities. They do not appear in Canon Robertson’s History of the Church. And strangest of all, Dean Milman cites the sentence in English in the text and in Greek in a note but in each case omits all mention of the letter of the Pope, marking however in the Greek that there is an omission. (Lat. Chr., Bk. II., Chap. III.) I also note that the translation in the English edition of Hefele’s History of the Councils (Vol. III., p. 51) is misleading and inaccurate, “Urged by the canons, and in accordance with the letter etc.” The participle by itself might mean nothing more than “urged” (vide Liddell and Scott on this verb and also ἐπείγω) but the adverb which precedes it, ἀναγκαίως , certainly is sufficient to necessitate the coacti of the old Latin version which I have followed, translating “compelled thereto.” It will also be noticed that while the prepositions used with regard to the “canons” and the “letter” are different, yet that their grammatical relation to the verb is identical is shewn by the τε—καὶ, which proves the translation cited above to be utterly incorrect.
