St. Paul Quite in Accordance with St. Peter and Other Apostles of the Circumcision. His Censure of St. Peter Explained, and Rescued from Marcion's Misapplication. The Strong Protests of This Epistle Against Judaizers. Yet Its Teaching is Shown to Be in Keeping with the Law and the Prophets. Marcion's Tampering with St. Paul's Writings Censured
For he remembered that the time had come of which the Psalm spoke, “Let us break their bands asunder, and cast off their yoke from us;” since the time when “the nations became tumultuous, and the people imagined vain counsels;” when “the kings of the earth stood up, and the rulers were gathered together against the Lord, and against His Christ,” in order that thenceforward man might be justified by the liberty of faith, not by servitude to the law, “because the just shall live by his faith.” Now, although the prophet Habakkuk first said this, yet you have the apostle here confirming the prophets, even as Christ did.
The object, therefore, of the faith whereby the just man shall live, will be that same God to whom likewise belongs the law, by doing which no man is justified. Since, then, there equally are found the curse in the law and the blessing in faith, you have both conditions set forth by the Creator: “Behold,” says He, “I have set before you a blessing and a curse.” You cannot establish a diversity of authors because there happens to be one of things; for the diversity is itself proposed by one and the same author.
Why, however, “Christ was made a curse for us,” is declared by the apostle himself in a way which quite helps our side, as being the result of the Creator's appointment. But yet it by no means follows, because the Creator said of old, “Cursed is every one that hangs on a tree,” that Christ belonged to another god, and on that account was accursed even then in the law. And how, indeed, could the Creator have cursed by anticipation one whom He knew not of? Why, however, may it not be more suitable for the Creator to have delivered His own Son to His own curse, than to have submitted Him to the malediction of that god of yours—in behalf, too, of man, who is an alien to him?
Now, if this appointment of the Creator respecting His Son appears to you to be a cruel one, it is equally so in the case of your own god; if, on the contrary, it be in accordance with reason in your god, it is equally so— nay, much more so— in mine. For it would be more credible that that God had provided blessing for man, through the curse of Christ, who formerly set both a blessing and a curse before man, than that he had done so, who, according to you, never at any time pronounced either.
“We have received therefore, the promise of the Spirit,” as the apostle says, “through faith,” even that faith by which the just man lives, in accordance with the Creator's purpose. What I say, then, is this, that that God is the object of faith who prefigured the grace of faith. But when he also adds, “For you are all the children of faith,” it becomes clear that what the heretic's industry erased was the mention of Abraham's name; for by faith the apostle declares us to be “children of Abraham,” and after mentioning him he expressly called us “children of faith” also.
But how are we children of faith? And of whose faith, if not Abraham's? For since “Abraham believed God, and it was accounted to him for righteousness;” since, also, he deserved for that reason to be called “the father of many nations,” while we, who are even more like him in believing in God, are thereby justified as Abraham was, and thereby also obtain life— since the just lives by his faith—it therefore happens that, as he in the previous passage called us “sons of Abraham,” since he is in faith our (common) father, so here also he named us “children of faith,” for it was owing to his faith that it was promised that Abraham should be the father of (many) nations.
As to the fact itself of his calling off faith from circumcision, did he not seek thereby to constitute us the children of Abraham, who had believed previous to his circumcision in the flesh? In short, faith in one of two gods cannot possibly admit us to the dispensation of the other, so that it should impute righteousness to those who believe in him, and make the just live through him, and declare the Gentiles to be his children through faith. Such a dispensation as this belongs wholly to Him through whose appointment it was already made known by the call of this self-same Abraham, as is conclusively shown by the natural meaning.
