And so under the first head is shown what unholy views they hold about the Divine Trinity: they affirm that the person of the Father, the Son, and the Holy Ghost is one and the same, as if the same God were named now Father, now Son, and now Holy Ghost: and as if He who begot were not one, He who was begotten, another, and He who proceeded from both, yet another; but an undivided unity must be understood, spoken of under three names, indeed, but not consisting of three persons. This species of blasphemy they borrowed from Sabellius, whose followers were rightly called Patripassians also: because if the Son is identical with the Father, the Son’s cross is the Father’s passion (patris-passio): and the Father took on Himself all that the Son took in the form of a slave, and in obedience to the Father. Which without doubt is contrary to the catholic faith, which acknowledges the Trinity of the Godhead to be of one essence (ὁμοούσιον) in such a way that it believes the Father, the Son, and the Holy Ghost indivisible without confusion, eternal without time, equal without difference: because it is not the same person but the same essence which fills the Unity in Trinity.
