John Chrysostom

"And shun profane novelties of speech." For they will not stop there. For when anything new has been introduced, it is ever producing innovations, and the error of him who has once left the safe harbor is infinite, and never stops. "For they will increase unto more ungodliness," he says, "And their word will eat as doth a canker." It is an evil not to be restrained, not curable by any medicine, it destroys the whole frame. He shows that novelty of doctrine is a disease, and worse than a disease. And here he implies that they are incorrigible, and that they erred not weakly but willfully.
