John 5:46 For if you believed Moses, you would believe Me; for he wrote about Me. 47 But if you do not believe his writings, how will you believe My words?
Any doctrine that teaches that Moses was done away with, that Messiah came to start a new religion or that claims Messiah/YHVH gave the church the authority to change YHVH's everlasting divine doctrine is out right blasphemy.
Are you disputing the New Testament?
Are you saying that Christians are bond to OT circumcision and dietary laws?
