And Callistus, who was in the habit of always associating with Zephyrinus, and, as I have previously stated, of paying him hypocritical service, disclosed, by force of contrast, Zephyrinus to be a person able neither to form a judgment of things said, nor discerning the design of Callistus, who was accustomed to converse with Zephyrinus on topics which yielded satisfaction to the latter. Thus, after the death of Zephyrinus, supposing that he had obtained (the position) after which he so eagerly pursued, he excommunicated Sabellius, as not entertaining orthodox opinions. He acted thus from apprehension of me, and imagining that he could in this manner obliterate the charge against him among the churches, as if he did not entertain strange opinions. He was then an impostor and knave, and in process of time hurried away many with him. And having even venom imbedded in his heart, and forming no correct opinion on any subject, and yet withal being ashamed to speak the truth, this Callistus, not only on account of his publicly saying in the way of reproach to us, “Ye are Ditheists,” but also on account of his being frequently accused by Sabellius, as one that had transgressed his first faith, devised some such heresy as the following. Callistus alleges that the Logos Himself is Son, and that Himself is Father; and that though denominated by a different title, yet that in reality He is one indivisible spirit. And he maintains that the Father is not one person and the Son another, but that they are one and the same; and that all things are full of the Divine Spirit, both those above and those below. And he affirms that the Spirit, which became incarnate in the virgin, is not different from the Father, but one and the same. And he adds, that this is what has been declared by the Saviour: “Believest thou not that I am in the Father, and the Father in me?” For that which is seen, which is man, he considers to be the Son; whereas the Spirit, which was contained in the Son, to be the Father. “For,” says (Callistus), “I will not profess belief in two Gods, Father and Son, but in one. For the Father, who subsisted in the Son Himself, after He had taken unto Himself our flesh, raised it to the nature of Deity, by bringing it into union with Himself, and made it one; so that Father and Son must be styled one God, and that this Person being one, cannot be two.” And in this way Callistus contends that the Father suffered along with the Son; for he does not wish to assert that the Father suffered, and is one Person, being careful to avoid blasphemy against the Father. (How careful he is!) senseless and knavish fellow, who improvises blasphemies in every direction, only that he may not seem to speak in violation of the truth, and is not abashed at being at one time betrayed into the tenet of Sabellius, whereas at another into the doctrine of Theodotus.
