Matthew Poole and continuators on Romans 3:27

27. Where is boasting then ? It is excluded. By what law? of works ? Nay but by the law of faith .

The Apostle doth, as it were, insult over them. q. d. Where is now the former Boasting of the Iews, as if they were so much better than the Gentiles; Or what is become of the ground of Boasting, that they, or either of them might think they had in the Law, or Philosophy, or any Moral Performances, vid. Ier. 9.23, 24.

If it be enquir'd upon what account this Boasting is excluded? We Answer plainly, It cannot be by that Law that Commands Works, as the condition of Acceptance and Justification; and tells us nothing by whom that Condition should be fulfilled; the Law being become weak to us, for such a purpose, by reason of Sin, Chap. 8.3.

i. e. The Gospel-Law which requires Faith, by which the Righteousness of Christ is imputed to us, and Attained by us. And this is call'd a Law of Faith, as some think, in Condescention to the Iews custome of Speaking, who are much delighted with the Name of the Law; and so that he might not be suspected of Novelty: But as most, it is an Hebraisme, denoting no more than the Doctrine or Prescript of Faith.
