I believe you’re misinterpreting Resty’s point.
The LDS Church agrees with the rest of Christianity that the Law of Moses was fulfilled in Christ; it was the lower law, and has been superceded.
The Abrahamic Covenant is a different matter. It applies to all of Israel - a word with several different valid definitions - and is still in quite full force.
I love my Church.
I never mention Moses!
Sorry this was for MHGinTN I never mention Moses!
