Augustine of Hippo — as excerpted in the Catena Aurea on John 18:22-24

“(Tr. cxiii) What can be truer, gentler, kinder, than this answer? He Who received the blow on the face neither wished for him who struck it that fire from heaven should consume him, or the earth open its mouth and swallow him; or a devil seize him; or any other yet more horrible kind of punishment. Yet had not He, by Whom the world was made, power to cause any one of these things to take place, but that He preferred teaching us that patience by which the world is overcome? Some one will ask here, why He did not do what He Himself commanded, i. e. not make this answer, but give the other cheek to the smiter? But what if He did both, both answered gently, and gave, not His check only to the smiter, but His whole body to be nailed to the Cross? And herein He shews, that those precepts of patience are to be performed not by posture of the body, but by preparation of the heart: for it is possible that a man might give his cheek outwardly, and yet be angry at the same time. How much better is it to answer truly, yet gently, and be ready to bear even harder usage patiently.”
