2 You should not therefore hold fast things earthly, although God does bestow them....See ye how that in fearing to lose things earthly, the Jews slew the King of Heaven. And what was done to them? They lost even those very things earthly: and in the place where they slew Christ, there they were slain: and when, being unwilling to lose the land, they slew the Giver of life, that same land being slain they lost; and at that very time when they slew Him, in order that by that very time they might be admonished of the reason wherefore they suffered these things. For when the city of the Jews was overthrown, they were celebrating the Passover, and with many thousands of men the whole nation itself had met together for the celebration of that festival. In that place God (through evil men indeed, but yet Himself good; through unjust men, but Himself just and justly) did so take vengeance upon them, that there were slain many thousands of men, and the city itself was overthrown. Of this thing in this Psalm “the understanding of Asaph” does complain, and in the very plaint the understanding as it were does distinguish things earthly from things heavenly, does distinguish the Old Testament from the New Testament: in order that you may see through what things you are passing, what you should look for, what to forsake, to what to cleave. Thus then he begins.
3. “Wherefore have You repelled us, O God, unto the end?”. “Have repelled unto the end,” in the person of the congregation which is properly called Synagogue. “Wherefore have You repelled us, O God, unto the end?” He censures not, but inquires “wherefore,” for what purpose, because of what have You done this? What have You done? “You have repelled us unto the end.” What is, “unto the end”? Perchance even unto the end of the world. Have You repelled us unto Christ, who is the End to every one believing? For, “Wherefore have You repelled us, O God, unto the end?” “Your spirit has been angry at the sheep of Your flock.” Wherefore were You angry at the sheep of Your flock, but because to things earthly we were cleaving, and the Shepherd we knew not?
4. “Remember Your congregation, which You have possessed from the beginning”. Can this by any means be the voice of the Gentiles? Hath He possessed the Gentiles from the beginning? Nay, but He has possessed the seed of Abraham, the people of Israel even according to the flesh, born of the Patriarchs our fathers: of whom we have become the sons, not by coming out of their flesh, but by imitating their faith. But those, possessed by God from the beginning, what befell them? “Remember Your congregation which You have possessed from the beginning. You have redeemed the rod of Your inheritance.” That same congregation of Yours, being the rod of Your inheritance, You have redeemed. This same congregation he has called “the rod of the inheritance.” Let us look back to the first thing that was done, when He willed to possess that same congregation, delivering it from Egypt, what sign He gave to Moses, when Moses said to Him, “What sign shall I give that they may believe me, that You have sent me? And God says to him, What do you bear in your hand? A rod. Cast it on to the ground,” etc. What does it intimate? For this was not done to no purpose. Let us inquire of the writings of God. To what did the serpent persuade man? To death. Therefore death is from the serpent. If death is from the serpent, the rod in the serpent is Christ in death. Therefore also when by serpents in the desert they were being bitten and being slain, the Lord commanded Moses to exalt a brazen serpent in the desert, and admonish the people that whosoever by a serpent had been bitten, should look thereupon and be made whole. Thus also it was done: thus also men, bitten by serpents, were made whole of the venom by looking upon a serpent. To be made whole of a serpent is a great Sacrament. What is it to be made whole of a serpent by looking upon a serpent? It is to be made whole of death by believing in one dead. And nevertheless Moses feared and fled. What is it that Moses fled from that serpent? What, brethren, save that which we know to have been done in the Gospel? Christ died and the disciples feared, and withdrew from that hope wherein they had been....But, at that time some thousands of the Jews themselves, the crucifiers of Christ, believed: and because they had been found at hand, they so believed as that they sold all that they had, and the price of their goods before the feet of the Apostles they laid. Because then this thing was hidden, and the redemption of the rod of God was to be more conspicuous in the Gentiles: he explains of what he says that which he has said, “You have redeemed the rod of Your inheritance.” This he has said not of the Gentiles in whom it was evident. But of what? “Mount Sion.” Yet even Mount Sion can be otherwise understood. “That one which You have dwelled in the same.” In the place where the People was aforetime, where the Temple was set up, where the Sacrifices were celebrated, where at that time were all those necessary things giving promise of Christ. A promise, when the thing promised is bestowed is now become superfluous....
5. “Lift up Your hand upon their pride at the end”. As You repelled us at the end, so “lift up Your hand upon the pride of them at the end.” The pride of whom? Of those by whom Jerusalem was overthrown. But by whom was it, but by the kings of the Gentiles? Well was the hand of Him lifted up upon the pride of them at the end: for they too have now known Christ. “For the end of the Law is Christ for righteousness to every one believing.” How well does he wish for them! As if angry he is speaking, and he is seeming to speak evil: and O that there would come to pass the evil which he speaks: nay now in the name of Christ that it is coming to pass let us rejoice. Now they holding the sceptre are being made subject to the Word of the Cross: now is coming to pass that which was foretold, “there shall adore Him all the kings of the earth, all nations shall serve Him.” Now on the brows of kings more precious is the sign of the Cross, than the jewel of a crown. “Lift up Your hand upon the pride of them at the end. How great things has the enemy of malice wrought in Your holy places!” In those which were Your holy places, that is, in the temple, in the priesthood, in all those sacraments which were at that time. In good truth the enemy at that time wrought. For the Gentiles at that time who did this, were worshipping false Gods, were adoring idols, were serving demons: nevertheless they wrought many evil things on the Saints of God. When could they if they had not been permitted? But when would they have been permitted, unless those holy things, at first promised, were no longer necessary, when He that had promised was Himself holden? Therefore, “how great things has the enemy of malice wrought in Your holy places!”
