Well, in my church experience, if someone starts the "Law of Christ" stuff - they mean "Everything but the 10 commandments is moot, no good, and I don't know why we even have this other 3/4ths of the book - it doesn't apply to me and it makes no sense".
Some say that I have a narrow view when I bring that up, but that is the bulk of the Christian outlook on this in the South where I have lived (VA, SC/GA, AL, MS, TX) and also overseas (Spain/Germany). There have been very rare exceptions to that. It doesn't mean
there aren't any who disagree, there just aren't many at all where I've been and the thousands of people I've met in
my life
