Victorinus of Pettau — on Rev 2:6 (Commentary on the Apocalypse of the Blessed John)

“"This thou hast also, that thou hatest the deeds of the Nicolaitanes." But because thou thyself hatest those who hold the doctrines of the Nicolaitanes, thou expectest praise. Moreover, to hate the works of the Nicolaitanes, which He Himself also hated, this tends to praise. But the works of the Nicolaitanes were in that time false and troublesome men, who, as ministers under the name of Nicolaus, had made for themselves a heresy, to the effect that what had been offered to idols might be exorcised and eaten, and that whoever should have committed fornication might receive peace on the eighth day. Therefore He extols those to whom He is writing; and to these men, being such and so great, He promised the tree of life, which is in the paradise of His God.”
