Tomus ad Antiochenos

⁶ The question of one Subsistence (Hypostasis) or three, not to be pressed.

Having accepted then these men's interpretation and defence of their language, we made enquiry of those blamed by them for speaking of One Subsistence, whether they use the expression in the sense of Sabellius, to the negation of the Son and the Holy Spirit, or as though the Son were non-substantial, or the Holy Spirit impersonal. But they in their turn assured us that they neither meant this nor had ever held it, but 'we use the word Subsistence thinking it the same thing to say Subsistence or Essence;' 'But we hold that there is One, because the Son is of the Essence of the Father, and because of the identity of nature. For we believe that there is one Godhead, and that it has one nature, and not that there is one nature of the Father, from which that of the Son and of the Holy Spirit are distinct.' Well, thereupon they who had been blamed for saying there were three Subsistences agreed with the others, while those who had spoken of One Essence, also confessed the doctrine of the former as interpreted by them. And by both sides Arius was anathematised as an adversary of Christ, and Sabellius, and Paul of Samosata, as impious men, and Valentinus and Basilides as aliens from the truth, and Manichæus as an inventor of mischief. And all, by God's grace, and after the above explanations, agree together that the faith confessed by the fathers at Nicæa is better than the said phrases, and that for the future they would prefer to be content to use its language.
