Luke 6:29

(ubi sup.) Now He said not, Bear humbly the rule of thy persecutor, but, Go on wisely, and prepare thyself to suffer what he desires thee to do; overcoming his insolence by thy great prudence, that he may depart with shame at thy excellent endurance. But some one will say, How can this be? When thou hast seen God made man, and suffering so many things for thee, dost thou still ask and doubt how it is possible to pardon the iniquities of thy fellow servants? Who has suffered what thy God has, when He was bound, scourged, enduring to be spat upon, suffering death?

(de Ser. Dom. lib. 1. c. 19.) He says this of garments, houses, farms, beasts of burdens, and generally of all property. But a Christian ought not to possess a slave as he does a horse or money. If a slave is more honourably governed by thee than by him who desires to take him from thee, I know not whether any one would dare to say, that he ought to be despised, as a garment (ut vestimentum.)

But this way of life was well adapted to the holy teachers who were about to preach throughout the earth the word of salvation, and if it had been their will to take vengeance upon their persecutors, had failed to call them to the knowledge of salvation. Now the old law commanded us not to injure one another; or if we are first injured, not to extend our wrath beyond the measure of the injurer, but the fulfilling of the law is in Christ and in His commands. Hence it follows, And unto him that smiteth thee on the one cheek, offer also the other. But the Lord would moreover have us to be despisers of property. As it follows, And him that taketh away thy cloak, forbid not to take thy coat also. For this is the soul's virtue, which is altogether alien from feeling the pleasure of wealth. For it becomes him who is merciful even to forget his misfortunes, that we may confer the same benefits upon our persecutors, whereby we assist our dear friends.
