Tertullian

“ Let us servants, therefore, follow our Lord closely; and be cursed patiently, that we may be able to be blessed. If I hear with too little equanimity some wanton or wicked word uttered against me, I must of necessity either myself retaliate the bitterness, or else I shall be racked with mute impatience. When, then, on being cursed, I smite (with my tongue,) how shall I be found to have followed the doctrine of the Lord, in which it has been delivered that “a man is defiled, [11] not by the defilements of vessels, but of the things which are sent forth out of his mouth.” ”

“ Chapter VIII.—Of Patience Under Personal Violence and Malediction.
We who carry about our very soul, our very body, exposed in this world [1] to injury from all, and exhibit patience under that injury; shall we be hurt at the loss [2] of less important things? [3] Far from a servant of Christ be such a defilement as that the patience which has been prepared for greater temptations should forsake him in frivolous ones. If one attempt to provoke you by manual violence, the monition of the Lord is at hand: “To him,” He saith, “who smiteth thee on the face, turn the other cheek likewise.” ”
