5 But why this? Because He “scourges every son whom He receives.” Why this? Because to men sinning was it said, “In the sweat of your face shall you eat bread.” Therefore because all these chastisements, in which all our bed is turned in our infirmity, man ought to acknowledge that he suffers for sin; let him turn himself, and say what follows: “I said, Lord, be merciful unto me; heal my soul, for I have sinned against You”. O Lord, by tribulations do Thou exercise me; to be scourged You judge every son whom You will receive, who spared not even the Only-Begotten. He indeed without sin was scourged; but I say, “I have sinned against You.”...
6. “Mine enemies speak evil of Me, When He shall die, then shall His Name perish”. Of this we have already spoken, and from this began.
7. “And entered in to see”. What Christ suffered, that suffers also the Church; what the Head suffered, that suffer also the Members. “For the disciple is not above his Master, nor the servant above his Lord.”...
If to Christ's Members you belong, come within, cling to the Head. Endure the tares if you are wheat, endure the chaff if you are grain. Endure the bad fish within the net if you are a good fish. Wherefore before the time of winnowing do you fly away? Wherefore before the time of harvest, do you root up the grain also with yourself? Wherefore before you have come to the shore, have you broken the nets? “They go abroad, and tell it.”
8. “All mine enemies whisper against Me unto the same thing”. Against Me all unto the same thing. How much better with me unto the same thing, than against me “unto the same thing.” What is, “Against me unto the same thing”? With one counsel, with one conspiring. Christ then speaks unto you, You consent against Me, consent ye to Me: why against Me? Wherefore not with Me? That same thing if you had always had, you had not divided you into schisms. For, says the Apostle, “I beseech you, brethren, that you all speak the same thing, and that there be no division among you.” “All mine enemies whisper against Me unto the same thing:” against Me do they “devise evil to Me.” To themselves rather, for “they have gathered iniquity to themselves;” but therefore to Me, because by their intention they are to be weighed: for not because to do nothing was in their power, to do nothing was in their will. For the devil lusted to extinguish Christ, and Judas would slay Christ; yet Christ slain and rising again, we are made alive, but to the devil and to Judas is rendered the reward of their evil will, not of our salvation....The intention wherewith they spoke, not what they spoke, did He consider, who related that they spoke evil of Him, “Against Me they devised evil to Me.” And what evil to Christ, to the Martyrs what evil? All has God turned to good.
9. “An ungodly word do they set forth against Me”. What sort of ungodly word? Listen to the Head Itself. “Come, let us kill Him, and the inheritance shall be ours.” Fools! How shall the inheritance be yours? Because ye killed Him? Lo! You even killed Him; yet shall not the inheritance be yours. “Shall not He that sleeps add this also, that He rise again”? When ye exulted that you had slain Him, He slept; for He says in another Psalm, “I slept.” They raged and would slay Me; “I slept.” If I had not willed, I had not even slept. “I slept,” because “I have power to lay down My life, and I have power to take it again.” “I laid Me down and slept, and rose up again.” Rage then the Jews; be “the earth given into the hands of the wicked,” be the flesh left to the hands of persecutors, let them on wood suspend it, with nails transfix it, with a spear pierce it. “Shall He that sleeps, not add this, that He rise up again?” Wherefore slept He? Because “Adam is the figure of Him that was to come.” And Adam slept, when out of his side was made Eve. Adam in the figure of Christ, Eve in the figure of the Church; whence she was called “the mother of all living.” When was Eve created? While Adam slept. When out of Christ's side flowed the Sacraments of the Church? While He slept upon the Cross....
10. “The man of My peace, in whom I trusted, which did eat of My bread, has enlarged his heel against Me”: has raised up his foot against Me: would trample upon Me. Who is this man of His peace? Judas. And in him did Christ trust, that He said, “in whom I trusted”? Did He not know him from the beginning? Did He not before he was born know that he would be? Had He not said to all His disciples, “I have chosen you twelve, and one of you is a devil”? How then trusted He in him, but that He is in His Members, and that because many faithful trusted in Judas, the Lord transferred this to Himself?...“The man of My peace, in whom I trusted, which did eat of My bread.” How showed He him in His Passion? By the words of His prophecy: by the sop He marked Him out, that it might appear said of him, “Which did eat of My bread.” Again, when he came to betray Him, He granted him a kiss, that it might appear said of him, “The man of My peace.”
11. “But You, O Lord, be merciful unto Me”. This is the person of a servant, this is the person of the needy and poor: for, “Blessed is he that understands upon the needy and poor One.” See, as it was spoken, “Be merciful unto Me, and raise Me up, and I will requite them,” so is it done. For the Jews slew Christ, lest they should lose their place. Christ slain, they lost their place. Rooted out of the kingdom were they, dispersed were they. He, raised up, requited them tribulation, He requited them unto admonition, not yet unto condemnation. For the city wherein the people raged, as a ramping and a roaring lion, crying out, “Crucify Him, Crucify Him,” the Jews rooted out therefrom, has now Christians, by not one Jew is inhabited. There is planted the Church of Christ, whence were rooted out the thorns of the synagogue. For truly this fire blazed “as the fire of thorns.” But the Lord was as a green tree. This said Himself, when certain women mourned Christ as dying....“For if they do these things in a green tree, what shall be done in a dry?” When can a green tree be consumed by the fire of thorns? For they blazed as fire among thorns. Fire consumes thorns, but whatsoever green tree it is applied to, is not easily kindled....Yet lest ye think that God the Father of Christ could raise up Christ, that is, the Flesh of His Son, and that Christ Himself, though He be the Word equal with the Father, could not raise up His own Flesh; hear out of the Gospel, “Destroy this temple, and in three days I will raise it up.” “But,” said the Evangelist (lest even after this we should doubt), “He spoke of the temple of His Body. Raise Me up, and I will requite them.”
