'the true circumcision defines the true jew' THIS distinction is the clue to understanding the key verse GAL 3:10 where according to my interpretation paul argues that those who 'do' the law are not 'fulfilling' the law
I assume that the 'upholding' of the deuteronomy quotation is semantically [or perhaps theologically] roughly equivalent to 'fulfilled' in GAL 5:14 the hebrew 'mekajam' of the verse certainly means 'to fulfill the requirement of' as well as 'to preserve' men of works of the law those who hold that works justify and practice accordingly are accursed by the law itself because of their misunderstanding of the true import of the law it is these to whom paul will later refer in ROM as 'you who have the written code & circumcision but break the law' THIS interpretation is supported as well by paul's own usage in other places for instance ROM 3:27 where he explicitly contrasts 'doing' which equals 'the law of works' with 'the law of faith' ~*~ THE NEXT VERSE is also quite simply understood as a midrashic argument although from the rabbinic point of view surely a 'midrash of lies' paul wishes to prove that 'nobody is justified before "G*D" by law' he first cites the verse of chavakuk which reads that the 'righteous live by faith' it follows from this that those who live by faith are the righteous i.e. the justified! he then argues that those who live by the law do NOT live by faith since the verse in LEV explicitly reads 'he who does them lives by them' i.e. one who does the commandments lives by them and NOT by faith SINCE then we know from chavakuk that the righteous live by faith he who lives by them and NOT by faith [and thereby does NOT fulfill the law] is NOT righteous - is NOT justified paul has then a perfect proof that 'nobody is justified before "G*D" by law' THIS interpretation obviates S.'s claim that paul is here denying the truth of a verse of the torah paul is using methods of interpretation that would not surpise any rabbi or pharisee [I suspect] although the results he arrives at would of course SHOCK them to their depths ] the phrase 'does them' in the LEV verse is precisely the same as 'to do them' in the verse of DEUT so this argument is a direct sequel to the previous one FINALLY it IS highly significant that in the LEV context the law which one does is specifically marked as that which marks jews off from gentiles: "YOU shall not act according to the way of life of egypt in which you lived! and you shall not act according to the way of life of cana'an into which I will cause you to go and you shall NOT live by their laws * YOU shall do my statutes [mishpatim] and keep MY laws and LIVE by them: I AM the LORD your "G*D" and you shall keep ALL my laws and all my statutes and DO THEM which if a man DOES WILL LIVE by them"
