Chapter 11.--Distinction Between the Children of the Old and of the New Testaments.
But there is plainly this great difference, that they who are established under the law, whom the letter killeth, do these things either with the desire of gaining, or with the fear of losing earthly happiness; and that thus they do not truly do them, since fleshly desire, by which sin is rather bartered or increased, is not healed by desire of another kind. These pertain to the old testament, which genders to bondage; because carnal fear and desire make them servants, gospel faith and hope and love do not make them children. But they who are placed under grace, whom the Spirit quickens, do these things of faith which worketh by love in the hope of good things, not carnal but spiritual, not earthly but heavenly, not temporal but eternal; especially believing on the Mediator, by whom they do not doubt but that a Spirit of grace is ministered to them, so that they may do these things well, and that they may be pardoned when they sin. These pertain to the new testament, are the children of promise, and are regenerated by God the Father and a free mother. Of this kind were all the righteous men of old, and Moses himself, the minister of the old testament, the heir of the new,--because of the faith whereby we live, of one and the same they lived, believing the incarnation, passion, and resurrection of Christ as future, which we believe as already accomplished,--even until John the Baptist himself, as it were a certain limit of the old dispensation, who, signifying that the Mediator Himself would come, not with any shadow of the future or allegorical intimation, or with any prophetical announcement, but pointing Him out with his finger, said: "Behold the Lamb of God; behold Him who taketh away the sin of the world." [2720] As if saying, Whom many righteous men have desired to see, on whom, as about to come, they have believed from the beginning of the human race itself, concerning whom the promises were spoken to Abraham, of whom Moses wrote, of whom the law and the prophets are witnesses: "Behold the Lamb of God, who taketh away the sin of the world." From this John and afterwards, all those things concerning Christ began to become past or present, which by all the righteous men of the previous time were believed, hoped for, desired, as future. Therefore the faith is the same as well in those who, although not yet in name, were in fact previously Christians, as in those who not only are so but are also called so; and in both there is the same grace by the Holy Spirit. Whence says the apostle: "We having the same Spirit of faith, according as it is written, I believed, therefore have I spoken; we also believe, and therefore speak." [2721]

Chapter 12.--The Old Testament is Properly One Thing--The Old Instrument Another.
Therefore, by a custom of speech already prevailing, in one way the law and all the prophets who prophesied until John are called the "Old Testament;" although this is more definitely called the "Old Instrument" rather than the "Old Testament;" but this name is used in another way by the apostolical authority, whether expressly or impliedly. For the apostle is express when he says, "Until this day, as long as Moses is read, remaineth the same veil in the reading of the old testament; because it is not revealed, because it is made of no effect in Christ." [2722] For thus certainly the old testament referred to the ministry of Moses. Moreover, he says, "That we should serve in the newness of the Spirit, and not in the oldness of the letter," [2723] signifying that same testament under the name of the letter. In another place also, "Who also hath made us able ministers of the new testament; not of the letter, but of the Spirit: for the letter killeth, but the Spirit maketh alive." [2724] And here, by the mention of the new, he certainly meant the former to be understood as the old. But much more evidently, although he did not say either old or new, he distinguished the two testaments and the two sons of Abraham, the one of the bondwoman, the other of the free, as I have above mentioned. For what can be more express than his saying, "Tell me, ye that desire to be under the law, have ye not heard the law? For it is written, that Abraham had two sons, the one by a bondmaid, the other by a freewoman. But he who was of the bondwoman was born after the flesh; but he of the freewoman was by promise. Which things are in allegory; for these are the two testaments; the one in the Mount Sinai, gendering to bondage, which is Agar. For Sinai is a mountain in Arabia, which is associated with Jerusalem which now is, for it is in bondage with her children. But Jerusalem that is above is free, which is our mother?" [2725] What is more clear, what more certain, what more remote from all obscurity and ambiguity to the children of the promise? And a little after, "Now we, brethren, as Isaac was, are the children of promise." [2726] Also a little after, "But we, brethren, are not children of the bondwoman, but of the free," [2727] with the liberty with which Christ has made us free. Let us, therefore, choose whether to call the righteous men of old the children of the bondwoman or of the free. Be it far from us to say, of the bondwoman; therefore if of the free, they pertain to the new testament in the Holy Spirit, whom, as making alive, the apostle opposes to the killing letter. For on what ground do they not belong to the grace of the new testament, from whose words and looks we convict and rebut such most frantic and ungrateful enemies of the same grace as these?
