19 “They tempted Me, and mocked Me with mocking”. That is, they derided Me, they insulted Me; this of the Head, this of the Body. Consider, Brethren, the glory of the Church which now is; remember its past dishonours, remember how once were Christians everywhere put to flight, and wherever found, mocked, beaten, slain, exposed to beasts, burned, men rejoicing against them. As it was to the Head, so it is also to the Body. For as it was to the Lord on the Cross, so has it been to His Body in all that persecution which was made but now: nor even now cease the persecutions of the same. Wherever men find a Christian, they are wont to insult, to persecute, to deride him, to call him dull, senseless, of no spirit, of no knowledge. Do they what they will, Christ is in Heaven: do they what they will, He has honoured His punishment, already has He fixed His Cross in the foreheads of all; the ungodly is permitted to insult, to rage he is not permitted; but yet from that which the tongue utters, is understood what he bears in his heart: “They gnashed upon Me with their teeth.”
