NINTH ARTICLE [III, Q. 46, Art. 9]
Whether Christ Suffered at a Suitable Time?
Objection 1: It would seem that Christ did not suffer at a suitable time. For Christ's Passion was prefigured by the sacrifice of the Paschal lamb: hence the Apostle says (1 Cor. 5:7): "Christ our Pasch is sacrificed." But the paschal lamb was slain "on the fourteenth day at eventide," as is stated in Ex. 12:6. Therefore it seems that Christ ought to have suffered then; which is manifestly false: for He was then celebrating the Pasch with His disciples, according to Mark's account (14:12): "On the first day of the unleavened bread, when they sacrificed the Pasch"; whereas it was on the following day that He suffered.
Obj. 2: Further, Christ's Passion is called His uplifting, according to John 3:14: "So must the Son of man be lifted up." And Christ is Himself called the Sun of Justice, as we read Mal. 4:2. Therefore it seems that He ought to have suffered at the sixth hour, when the sun is at its highest point, and yet the contrary appears from Mk. 15:25: "It was the third hour, and they crucified Him."
Obj. 3: Further, as the sun is at its highest point in each day at the sixth hour, so also it reaches its highest point in every year at the summer solstice. Therefore Christ ought to have suffered about the time of the summer solstice rather than about the vernal equinox.
Obj. 4: Further, the world was enlightened by Christ's presence in it, according to John 9:5: "As long as I am in the world I am the light of the world." Consequently it was fitting for man's salvation that Christ should have lived longer in the world, so that He should have suffered, not in young, but in old, age.
On the contrary, It is written (John 13:1): "Jesus, knowing that His hour was come for Him to pass out of this world to the Father"; and (John 2:4): "My hour is not yet come." Upon which texts Augustine observes: "When He had done as much as He deemed sufficient, then came His hour, not of necessity, but of will, not of condition, but of power." Therefore Christ died at an opportune time.
I answer that, As was observed above (A. 1), Christ's Passion was subject to His will. But His will was ruled by the Divine wisdom which "ordereth all things" conveniently and "sweetly" (Wis. 8:1). Consequently it must be said that Christ's Passion was enacted at an opportune time. Hence it is written in De Qq. Vet. et Nov. Test., qu. lv: "The Saviour did everything in its proper place and season."
Reply Obj. 1: Some hold that Christ did die on the fourteenth day of the moon, when the Jews sacrificed the Pasch: hence it is stated (John 18:28) that the Jews "went not into Pilate's hall" on the day of the Passion, "that they might not be defiled, but that they might eat the Pasch." Upon this Chrysostom observes (Hom. lxxxii in Joan.): "The Jews celebrated the Pasch then; but He celebrated the Pasch on the previous day, reserving His own slaying until the Friday, when the old Pasch was kept." And this appears to tally with the statement (John 13:1-5) that "before the festival day of the Pasch . . . when supper was done" . . . Christ washed "the feet of the disciples."
But Matthew's account (26:17) seems opposed to this; that "on the first day of the Azymes the disciples came to Jesus, saying: Where wilt Thou that we prepare for Thee to eat the Pasch?" From which, as Jerome says, "since the fourteenth day of the first month is called the day of the Azymes, when the lamb was slain, and when it was full moon," it is quite clear that Christ kept the supper on the fourteenth and died on the fifteenth. And this comes out more clearly from Mk. 14:12: "On the first day of the unleavened bread, when they sacrificed the Pasch," etc.; and from Luke 22:7: "The day of the unleavened bread came, on which it was necessary that the Pasch should be killed."
