65 At the pouring forth, then, of this ointment all rejoice; Judas alone speaks against it. So, too, now he who is a sinner speaks against it, he who is a traitor blames it, but he is himself blamed by Christ, as he knows not the remedy of the Lord's death, and understands not the mystery of that so great burial. For the Lord both suffered and died that He might redeem us from death. This is manifest from the most excellent value from His death, which is sufficient for the absolution of the sinner, and his restoration to fresh grace; so that all may come and wonder at his sitting at table with Christ, and may praise God, saying: “Let us eat and feast, for he was dead and is alive again, had perished and is found.” But any one devoid of faith objects: “Why does He eat with publicans and sinners?” This is his answer: “They that are whole have no need of the physician, but they that are sick.”
