You can backout of the discussion; but for the record I never said that the scriptures were something that one could never have a confident, justified interpretation of. I merely pointed out some of the errors of MAD and why it is a bad interpretation.
You want things simple; but Paul is not easily understood, as Peter testifies. If you aren't willing to dig deep and really study these matters then you won't understand Paul's meaning.
For instance - you think "law" only carries one meaning/reference: the Mosaic Law. This is not true for Paul; he uses the term freely for many things - like one's conscience, and even temptation/sin. More relevant to the discussion - he uses it to distinguish the customs and traditions of the Jews from God's will (the law vs God's Law/Christ's Law/the Law of Faith).
