Tertullian

“ Two human beings were formed by the angels—Cain and Abel. On their account arose great contentions and discords among the angels; for this reason, that Virtue which was above all the Virtues—which they style the Mother—when they said [17] that Abel had been slain, willed this Seth of theirs to be conceived and born in place of Abel, in order that those angels might be escheated who had created those two former human beings, while this pure seed rises and is born. For they say that there had been iniquitous permixtures of two angels and human beings ”

“ Because the powers of this world [15] were unwilling that Christ should suffer, lest through His death salvation should be prepared for mankind, he, consulting for the salvation of mankind, betrayed Christ, in order that there might be no possibility at all of the salvation being impeded, which was being impeded through the Virtues which were opposing Christ’s passion; and thus, through the passion of Christ, there might be no possibility of the salvation of mankind being retarded. ”

“ To these are added those heretics likewise who are called Ophites: [1] for they magnify the serpent to such a degree, that they prefer him even to Christ Himself; for it was he, they say, who gave us the origin of the knowledge of good and of evil. ”
