You might want to take a look at “The Apostle Paul and Moral Absolutes.” Don’t be put off by it’s brevity. It asks a simple question, “Does acknowledging the impossibility of moral perfection, in Pauline phrasing “meeting the demands of the Law,” necessarily require Redemption? Is the Redemption necessary?

Why fetishize verbal formulas, phrasings, stories, beliefs at all? The psychological appeal is simple fetishizing verbal formulas (convictions, formulas of faith, the Apostle’s Creed or the Nicene Creed, for example) turns avoidance of inconveniences (the place of women, minorities, or consider the treatment of the Jews by the “Religion of Love” throughout its history).
