I’m trying to understand your position?
The “law” is not applied to Christians today, you’re saying, maybe since it was given by angels and not God. But the Ten Commandments are cooking along because they were given to Moses directly?
Maybe a quick glance at James 2:10–11 would be helpful. Sinai commandments are listed and called ‘law’.
The ‘angel’ discussion regarding Sinai- by Stephen in Acts 7:53 and Paul in Galatians 3:19- don’t seem to be marking out which rules are to be followed and which aren’t.
I’m not sure why you can’t accept the “commandment” of John 13:34 — “Love one another.”
