Against Heresies: Book IV
Chapter XXXIII.--Whosoever confesses that one God is the author of both Testaments, and diligently reads the Scriptures in company with the presbyters of the Church, is a true spiritual disciple; and he will rightly understand and interpret all that the prophets have declared respecting Christ and the liberty of the New Testament.
6.
He shall also judge false prophets, who, without having received the gift of prophecy from God, and not possessed of the fear of God, but either for the sake of vainglory, or with a view to some personal advantage, or acting in some other way under the influence of a wicked spirit, pretend to utter prophecies, while all the time they lie against God.
