Derek Leman bases the so-called ethnic-ethical distinction on the theory that some laws in the Bible are moral and some laws are not moral. No, seriously, that's what he says. For example:
"The blood prohibition is not a moral law. It is a priestly law," from:http://www.derekleman.com/musings/moral-law-revealed-torah-noah/ (cached)By the way, just for the record, something is considered "moral" if it is "good." The opposite of moral is therefore something that is "bad."
So, according to Derek's view, once a Gentile distinguishes between Biblical laws which are moral (and therefore universal) and Biblical laws which are immoral (and therefore intended only for Israel), then a Gentile is able to live his calling as a righteous Gentile.
Does that sound like a good guideline to follow? Or does this sound like the kind of thinking that might lead someone astray?
But, as of 9/16/2015, the UMJC apparently thinks that Derek Leman's analysis is correct because this is the teacher to whom they cite in their position papers (e.g. "Gentiles and Torah").
