15. If, then, any one wishes to please all, he must strive in everything to do, not what is useful for himself, but what is useful for many, as also Paul strove to do. For this is “to be conformed to the image of Christ,” Rom. viii. 29. namely, when one does not strive for what is another’s, and does not deprive another of something so as to gain it for oneself. For Christ our Lord, Phil. ii. 6, 7. though He was in the form of God, emptied Himself so as to take on Himself the form of man, which He wished to enrich with the virtue of His works. Wilt thou, then, spoil him whom Christ has put on? Wilt thou strip him whom Christ has clothed? For this is what thou art doing when thou dost attempt to increase thine own advantage at another’s loss.
