The Divine Institutes

But with reference to the cross, it has great force and meaning, which I will now endeavour to show. For God (as I have before explained), when He had determined to set man free, sent as His ambassador to the earth a teacher of virtue, who might both by salutary precepts train men to innocence, and by works and deeds before their eyes might open the way of righteousness, by walking in which, and following his teacher, man might attain to eternal life. He therefore assumed a body, and was clothed in a garment of flesh, that He might hold out to man, for whose instruction He had come, examples of virtue and incitements to its practice. But when He had afforded an example of righteousness in all the duties of life, in order that He might teach man also the patient endurance of pain and contempt of death, by which virtue is rendered perfect and complete, He came into the hands of an impious nation, when, by the knowledge of the future which He had, He might have avoided them, and by the same power by which He did wonderful works He might have repelled them. Therefore He endured tortures, and stripes, and thorns. At last He did not refuse even to undergo death, that under His guidance man might triumph over death, subdued and bound in chains with all its terrors. But the reason why the Most High Father chose that kind of death in preference to others, with which He should permit Him to be visited, is this. For some one may perchance say: Why, if He was God, and chose to die, did He not at least suffer by some honourable kind of death? Why was it by the cross especially? Why by an infamous kind of punishment, which may appear unworthy even of a man if he is free, although guilty? First of all, because He, who had come in humility that He might bring assistance to the humble and men of low degree, and might hold out to all the hope of safety, was to suffer by that kind of punishment by which the humble and low usually suffer, that there might be no one at all who might not be able to imitate Him. In the next place, it was in order that His body might be kept unmutilated, since He must rise again from the dead on the third day.

Nor ought any one to be ignorant of this, that He Himself, speaking before of His passion, also made it known that He had the power, when He willed it, of laying down His life and of taking it again. Therefore, because He had laid down His life while fastened to the cross, His executioners did not think it necessary to break His bones (as was their prevailing custom), but they only pierced His side. Thus His unbroken body was taken down from the cross, and carefully enclosed in a tomb. Now all these things were done lest His body, being injured and broken, should be rendered unsuitable for rising again. That also was a principal cause why God chose the cross, because it was necessary that He should be lifted up on it, and the passion of God become known to all nations. For since he who is suspended upon a cross is both conspicuous to all and higher than others, the cross was especially chosen, which might signify that He would be so conspicuous, and so raised on high, that all nations from the whole world should meet together at once to know and worship Him. Lastly, no nation is so uncivilized, no region so remote, to which either His passion or the height of His majesty would be unknown. Therefore in His suffering He stretched forth His hands and measured out the world, that even then He might show that a great multitude, collected together out of all languages and tribes, from the rising of the sun even to his setting, was about to come under His wings, and to receive on their foreheads that great and lofty sign. And the Jews even now exhibit a figure of this transaction when they mark their thresholds with the blood of a lamb. For when God was about to smite the Egyptians, to secure the Hebrews from that infliction He had enjoined them to slay a white lamb without spot, and to place on their thresholds a mark from its blood. And thus, when the first-born of the Egyptians had perished in one night, the Hebrews alone were saved by the sign of the blood: not that the blood of a sheep had such efficacy in itself as to be the safety of men, but it was an image of things to come. For Christ was the white lamb without spot; that is, He was innocent, and just, and holy, who, being slain by the same Jews, is the salvation of all who have written on their foreheads the sign of blood— that is, of the cross, on which He shed His blood. For the forehead is the top of the threshold in man, and the wood sprinkled with blood is the emblem of the cross. Lastly, the slaying of the lamb by those very persons who perform it is called the paschal feast, from the word “paschein,” because it is a figure of the passion, which God, foreknowing the future, delivered by Moses to be celebrated by His people. But at that time the figure was efficacious at the present for averting the danger, that it may appear what great efficacy the truth itself is about to have for the protection of God's people in the extreme necessity of the whole world. But in what manner or in what region all will be safe who have marked on the highest part of their body this sign of the true and divine blood, I will show in the last book.
