John Chrysostom
Catena Aurea · Lukasevangelium 23
Then said Jesus, Father, forgive them; for they know not what they do. And they parted his raiment, and cast lots. And the people stood beholding. And the rulers also with them derided him, saying, He saved others; let him save himself, if he be Christ, the chosen of God. And the soldiers also mocked him, coming to him, and offering him vinegar, And saying, If thou be the king of the Jews, save thyself.
Because the Lord had said, Pray for them that persecute you, (Matt. 5:44.) this likewise He did, when He ascended the cross, as it follows, Then said Jesus, Father, forgive them, not that He was not able Himself to pardon them, but that He might teach us to pray for our persecutors, not only in word, but in deed also. But He says, Forgive them, if they should repent. For He is gracious to the penitent, if they are willing after so great wickedness to wash away their guilt by faith.
