Romans 3:27

ποῦ οὖν, where, since this is the case, is boasting? ἐξεκλείσθη : for the use of the tense, cf. ἐβλήθη and ἐξηράνθη in John 15:6; it is equivalent to, “is peremptorily, or once for all, shut out”. διὰ ποίου νόμου; By what kind of law? In other words, How is the “law,” the divinely appointed spiritual order, or constitution, which excludes boasting, to be characterised? Is it by “the works” which it prescribes, and which those who live under it perform? No: its character is given when we call it a constitution or law of “faith”. Νόμος in these brief questions is evidently used in a wide sense to denote the religious order or system under which men live, regarded as established by God, and having His authority; the O.T. religion and the N.T. religion, unlike, and in some ways opposed, as they are, are alike νόμος divine institutes.
