If you instruct the brothers of these things, you will be a good servant of Christ Jesus, nourished in the words of the faith, and of the good doctrine which you have followed.

 The heretics of Ephesus were propagating a heresy with very definite consequences for life. As we have already seen, these heretics were Gnostics; and the essence of Gnosticism was that spirit is altogether good and matter altogether evil. One of the consequences was that there were men who preached that everything to do with the body was evil and that everything in the world was evil. In Ephesus this issued in two definite errors. The heretics insisted that men must, as far as possible, abstain from food, for food was material and therefore evil; food ministered to the body and the body was evil. They also insisted that a man must abstain from marriage, for the instincts of the body were evil and must be entirely suppressed.
