Hippolytus

“ Noetus asserts that there is one Father and God of the universe, and that He made all things, and was imperceptible to those that exist when He might so desire. Noetus maintained that the Father then appeared when He wished; and He is invisible when He is not seen, but visible when He is seen. And this heretic also alleges that the Father is unbegotten when He is not generated, but begotten when He is born of a virgin; as also that He is not subject to suffering, and is immortal when He does not suffer or die. ”

“ For Spirit, as the Deity, is, he says, not any being different from the Logos, or the Logos from the Deity; therefore this one person, (according to Callistus,) is divided nominally, but substantially not so. He supposes this one Logos to be God, and affirms that there was in the case of the Word an incarnation. And he is disposed (to maintain) , that He who was seen in the flesh and was crucified [2] is Son, but that the Father it is who dwells in Him. Callistus thus at one time branches off into the opinion of Noetus, but at another into that of Theodotus, and holds no sure doctrine. ”
