1 Before the festival day of the pasch, Jesus knowing that his hour was come, that he should pass out of this world to the Father: having loved his own who were in the world, he loved them unto the end.
Augustine: The Greek word to suffer being paschein, pascha has been thought to mean passion, as being derived from the above word. But in Hebrew, pascha is a passing over; the feast deriving its name from the passing, of the people of God over the Red Sea into Egypt. All was now to take place in reality, of which that passover was the type. Christ was led as a lamb to the slaughter; whose blood sprinkled upon our doorposts, i.e. whose sign of the cross marked on our foreheads, delivers us from the dominion of this world, as from Egyptian bondage. And we perform a most wholesome journey or passover, when we pass over from the devil to Christ, from this unstable world to His sure kingdom.
Chrysostom: He left nothing undone which one who greatly loved should do. He reserved this for the last, that their love might be increased by it, and to prepare them by such consolation for the trials that were coming. His own He calls them, in the sense of intimacy. . . . His own which were in the world, He loved all along, and at the last manifested His love in completeness: He loved them unto the end.
Augustine: He loved them unto the end, i.e. that they themselves too might pass out of this world, by love, to Him their head. For what is unto the end, but to Christ? For Christ is the end of the law for righteousness to everyone that believeth [Rom 10:4]. . . . God forbid that He should end His love by death, who is not ended by death.
