"...here is the first statement about justification in Romans, and lo and behold it affirms justification according to works! The doers of the law, he says, will be justified (2.13). Shock, horror; Paul cannot (so many have thought) have really meant it. So the passage has been treated as a hypothetical position which Paul then undermines by showing that nobody can actually achieve it; or, by Sanders for instance, as a piece of unassimilated Jewish preaching which Paul allows to stand even though it conflicts with other things he says. But all such theories are undermined by exegesis itself, not least by observing the many small but significant threads that stitch Romans 2 into the fabric of the letter as a whole. Paul means what he says. Granted, he redefines what ‘doing the law’ really means; he does this in chapter 8, and again in chapter 10, with a codicil in chapter 13. But he makes the point most compactly in Philippians 1.6: he who began a good work in you will bring it to completion on the day of Christ Jesus. The ‘works’ in accordance with which the Christian will be vindicated on the last day are not the unaided works of the self-help moralist. Nor are they the performance of the ethnically distinctive Jewish boundary-markers (sabbath, food-laws and circumcision). They are the things which show, rather, that one is in Christ; the things which are produced in one’s life as a result of the Spirit’s indwelling and operation."
