Prescription against Heretics 6

No more on this, if it is the same Paul who elsewhere, writing to the Galatians, counts heresies among the sins of the flesh, and who advises Titus that a heretical man should be refused after a first rebuke, because such a man is perverted and sins, being self-condemned. Indeed, in almost every letter, pressing that adulterous doctrines be shunned, he censures heresies. Their works are adulterous doctrines, called heresies by a Greek word, in the sense of the choice that a person makes either in founding them or in taking them up. That is why he called the heretic self-condemned: because he has chosen for himself that in which he is condemned. For us, however, it is not lawful to indulge anything of our own choosing, nor to choose what someone else has introduced of his own choosing. We have the apostles of the Lord as our authorities, who did not themselves choose anything of their own will to introduce, but faithfully delivered to the nations the teaching they had received from Christ. So even if an angel from heaven preached a different gospel, he would be called anathema by us. The Holy Spirit had already foreseen that there would be, in a certain virgin Philumene, an angel of seduction transforming himself into an angel of light, led by whose signs and illusions Apelles introduced a new heresy.
