1 Corinthians 10:14
2 “Wherefore, my brethren, flee from idolatry.”
Again he courts them by the name of kindred, and urges them to be rid of this sin with all speed. For he did not say, simply, depart, but “flee;” and he calls the matter “idolatry,” and no longer bids them quit it merely on account of the injury to their neighbor, but signifies that the very thing of itself is sufficient to bring a great destruction.
