John 19:31

The Jews who strained at a gnat and swallowed a camel after their audacious wickedness, reason scrupulously about the day: The Jews therefore because it was the preparation, that the bodies should not remain upon the cross on the Sabbath.

Parasceue, i.e. preparation: the sixth day was so called because the children of Israel prepared twice the number of loaves on that day. For that Sabbath day was an high day, i. e. on account of the feast of the passover. Besought Pilate that their legs might be broken.

Not in order to take away the legs, but to cause death, that they might be taken down from the cross, and the feast day not be defiled by the sight of such horrid torments.

For it was commanded in the Law that the sun should not set on the punishment of anyone; or they were unwilling to appear tormentors and homicides on a feast day.

How forcible is truth: their own devices it is that accomplish the fulfillment of prophecy: Then came the soldiers and broke the legs of the first, and of the other which was crucified with Him. But when they came to Jesus, an saw that He was dead already, they broke not His legs: but one of the soldiers with a spear pierced His side.

To please the Jews, they pierce Christ, thus insulting even His lifeless body. But the insult issues in a miracle: for a miracle it is that blood should flow from a dead body.

The Evangelist has expressed himself cautiously; not struck, or wounded, but opened His side: whereby was opened the gate of life, from whence the sacraments of the Church flowed, without which we cannot enter into that life which is the true life: And forthwith came thereout blood and water. That blood was shed for the remission of sins, that water tempers the cup of salvation. This it was which was prefigured when Noah was commanded to make a door in the side of the ark, by which the animals that were not to perish by the deluge entered; which animals prefigured the Church. To shadow forth this, the woman was made out of the side of the sleeping man; for this second Adam bowed His head, and slept on the cross, that out of that which came therefrom, there might be formed a wife for Him. O death, by which the dead are quickened, what can be purer than that blood, what more salutary than that wound!

This being the source whence the holy mysteries are derived, when you approach the awful cup, approach it as if you were about to drink out of Christ’s side.

Shame then upon them who mix not water with the wine in the holy mysteries: they seem as if they believed not that the water flowed from the side. Had blood flowed only, a man might have said that there was some life left in the body, and that that was as why the blood flowed. But the water flowing is an irresistible miracle, and therefore the Evangelist adds, And he that saw it bare record.

As if to say, I did not hear it from others, but saw it with mine own eyes. And his record is true, he adds, not as if he had mentioned something so wonderful that his account would be suspected, but to stop the mouths of heretics, and in contemplation of the deep value of those mysteries which he announces. And he knows that he says true, the you might believe.

He that saw it knows; let him that saw not believe his testimony. He gives testimonies from the Scriptures to each of these two things he relates. After, they brake not His legs, He adds, For these things were done, that the Scripture should be fulfilled, A bone of Him shall not be broken, a commandment which applied to the sacrifice of the paschal lamb under the old law, which sacrifice foreshadowed our Lord’s. Also after, One of the soldiers with a spear opened His side, then follows another Scripture testimony; And again another Scripture said, They shall look on Him whom they pierced, a prophecy which implies that Christ will come in the very flesh in which He was crucified.

This testimony is taken from Zacharias.

Now, from whom comes this grace, but from Him who proclaimed the promise thereof? Who is (our) Father, but He who is also our Maker? Therefore, after such affluence (of grace), they should not have returned “to weak and beggarly elements.” By the Romans, however, the rudiments of learning are wont to be called elements . He did not therefore seek, by any depreciation of the mundane elements, to turn them away from their god, although, when he said just before, “Howbeit, then, ye serve them which by nature are no gods,” he censured the error of that physical or natural superstition which holds the elements to be god; but at the God of those elements he aimed not in this censure. …

But after His public ministry He did not eat of the lamb, but Himself suffered as the true Lamb in the Paschal feast, as John, the divine and evangelist, teaches us in the Gospel written by him, where he thus speaks: “Then led they Jesus from Caiaphas unto the hall of judgment: and it was early; and they themselves went not into the judgment-hall, lest they should be defiled, but that they might eat the passover.” And after a few things more. “When Pilate therefore heard that saying, he brought Jesus forth, and sat down in the judgment-seat, in a place that is called the Pavement, but in the Hebrew, Gabbatha. …

16. Wherefore, since the spirit is to be preferred to the body, and the death of the spirit means that God has left it, but the death of the body that the spirit has left it; and since herein lies the punishment in the death of the body, that the spirit leaves the body against its will, because it left God willingly; so that, whereas the spirit left God because it would, it leaves the body although it would not; nor leaves it when it would, unless it has offered violence to itself, whereby the body itself is slain: the spirit of the Mediator showed how it was through no punishment of sin that He came to the death of the flesh, because He did not leave it against His will, but because He willed, when He willed, as He willed. For because He is so commingled [with the flesh] by the Word of God as to be one, He says: “I have power to lay down my life, and I have power to take it again. …

6. In short, that ye may know that the words refer, not to the necessity of His dying, but to His power, I speak this for the sake of some who, when they hear “His hour was not yet come,” are determined on believing in fate, and their hearts become infatuated; that ye may know, then, that it was His power of dying, recollect the passion, look at Him crucified. While hanging on the tree, He said, “I thirst.” They, having heard this, offered to Him on the cross vinegar by a sponge on a reed. He received it, and said, “It is finished;” and, bowing His head, gave up the ghost. You see His power of dying, that He waited for this, until all things should be fulfilled that had been foretold concerning Him, to take place before His death. …

Ver. 31 . “Because it was the Preparation, that the bodies should not remain upon the cross, they besought Pilate that their legs might be broken.”
