Irenaeus

But as many as separate from the Church, and give heed to such old wives' fables as these, are truly self-condemned; and these men Paul commands us, "after a first and second admonition, to avoid." And John, the disciple of the Lord, has intensified their condemnation, when he desires us not even to address to them the salutation of "good-speed;" for, says he, "He that bids them be of good-speed is a partaker with their evil deeds;" and that with reason, "for there is no good-speed to the ungodly," saith the Lord.
