The present Greek text has ἐκ δύο φύσεων while the old Latin translation has, in duabus naturis. After what had been repeatedly said in this session on the difference between “in two natures” and “of two natures,” and in opposition to the latter formula, there can be no doubt whatever that the old Latin translator had the more accurate text before him, and that it was originally ἐν δύο φύσεσιν. This, however, is not mere supposition, but is expressly testified by antiquity: (1) by the famous Abbot Euthymius of Palestine, a contemporary of the Council of Chalcedon, of whose disciples several were present as bishops at our Council (cf. Baron. ad. ann. 451, n. 152 sq.). We still have a judgment of his which he gave respecting the decree of Chalcedon concerning the faith, and in which he repeats the leading doctrine in the words of the Synod itself. At our passage he remarks: ἐν δύο φύσεσι γνωρίζεσθαι ὁμολογεῖ τὸν ἕνα Χριστὸν κ.τ.λ. The fragment of his writings on the subject is found in the Vita S. Euthymii Abbatis, written by his pupil Cyril in the Analecta Græca of the monks of St. Maur, t. i., p. 57, printed in Mansi, t. vii., p. 774 sq. (2) The second ancient witness is Severus, from a.d. 513 Monophysite patriarch of Antioch, who represents it as a great reproach and an unpardonable offence in the fathers of Chalcedon that they had declared: ἐν δύο φύσεσιν ἀδιαιρέτοις γνωρίζεσθαι τον Χριστὸν (see the Sententiæ Severi in Mansi, t. vii., p. 839). (3) Somewhat more than a hundred years after the Council of Chalcedon, Evagrius copied its decree concerning the faith in extenso into his Church History (lib. ii., 4), and, in fact, with the words: ἐν δύο φύσεσιν ἀσυγχύτως κ.τ.λ. (ed. Mog., p. 294). (4) In the conference on religion held between the Severians and the orthodox at Constantinople, a.d. 553, the former reproached the Synod of Chalcedon with having put in duabus naturis, instead of ex duabus naturis, as Cyril and the old fathers had taught (Mansi, t. viii., p. 892; Hardouin, t. ii., p. 1162). (5) Leontius of Byzantium maintains quite distinctly, in the year 610, in his work De Sectis, that the Synod taught ἕνα Χριστὸν ἐν δύο φύτεσιν ὰσυγχύτως κ.τ.λ.
