Romans 15:8

Again, he is speaking of Christ's concern for us, still holding to the same topic, and showing what great things He hath done for us, and how "He pleased not Himself." And besides this, there is another point which he makes good, that those of the Gentiles are debtors to a larger amount unto God. And if to a larger amount, then they ought to bear with the weak among the Jews. For since he had spoken very sharply to such, lest this should make these elated, he humbles their unreasonableness, by showing that it was by "promise made to the fathers" that they had the good things given them, while they of the Gentiles had them out of pity and love toward man only. And this is the reason of his saying, "And that the Gentiles might glorify God for his mercy." But that what is said may be made plainer, it is well to listen once more to the words themselves, that you may see what Christ's having been made "a Minister of the circumcision for the truth of God, to confirm the promises made unto the fathers," means. What then is that which is stated? There had been a promise made to Abraham, saying, "Unto thee will I give the earth, and to thy seed, and in thy seed shall all the nations be blessed." But after this, they of the seed of Abraham all became subject to punishment. For the Law wrought wrath unto them by being transgressed, and thenceforward deprived them of that promise made unto the fathers. Therefore the Son came and wrought with the Father, in order that those promises might come true, and have their issue. For having fulfilled the whole Law in which He also fulfilled the circumcision, and having by it, and by the Cross, freed them from the curse of the transgression, He suffered not this promise to fall to the ground. When then he calls Him "a Minister of the circumcision," he means this, that by having come and fulfilled the Law, and been circumcised, and born of the seed of Abraham, He undid the curse, stayed the anger of God, made also those that were to receive the promises fit for them, as being once for all freed from their alienation. To prevent then these accused persons from saying, How then came Christ to be circumcised and to keep the whole Law? he turns their argument to the opposite conclusion. For it was not that the Law might continue, but that He might put an end to it, and free thee from the curse thereof, and set thee entirely at liberty from the dominion of that Law. For it was because thou hadst transgressed the Law, that He fulfilled it, not that thou mightest fulfil it, but that He might confirm to thee the promises made unto the fathers, which the Law had caused to be suspended, by showing thee to have offended, and to be unworthy of the inheritance. And so thou also art saved by grace, since thou wast cast off. Do not thou then bicker, nor perversely cling to the Law at this unsuitable time, since it would have cast thee also out of the promise, unless Christ had suffered so many things for thee. And He did suffer these, not because thou wast deserving of salvation, but that God might be true.
