Pelagius — on Rom 12:2 (PELAGIUS'S COMMENTARY ON ROMANS)

“Do not be like the children of the world, you who have been made children of God, but renew your mind, by which the body is governed and all the members are directed. Thus even the movements of the body will be renewed, so that you may be able to recognize the will of God and his mind, for these are revealed only to a renewed mind.”
