And hence, Judas, you are proved more criminal and unhappier than all; for when repentance should have called you back to the Lord, despair dragged you to the halter. You should have awaited the completion of your crime, and have put off your ghastly death by hanging, until Christ's Blood was shed for all sinners. And among the many miracles and gifts of the Lord's which might have aroused your conscience, those holy mysteries, at least, might have rescued you from your headlong fall, which at the Paschal supper you had received, being even then detected in your treachery by the sign of Divine knowledge. Why do you distrust the goodness of Him, Who did not repel you from the communion of His body and blood, Who did not deny you the kiss of peace when you came with crowds and a band of armed men to seize Him. But O man that nothing could convert, O "spirit going and not returning ," you followed your heart's rage, and, the devil standing at your right hand, turned the wickedness, which you had prepared against the life of all the saints, to your own destruction, so that, because your crime had exceeded all measure of punishment, your wickedness might make you your own judge, your punishment allow you to be your own hangman.
Leo I, Sermon 54, On the Passion.
