NT: 

Paul instructed the gentiles wanting to turn to God that they must:

Love neighbor as themselves (Lev 19:18)

Not commit sexual immorality (Lev 18)

Not use idols (Ex 20:4)

Not murder (Ex 20:13)

Not steal (Ex 20:15)

Not to lie (Ex 20:16)

Not envy (Ex 20:17)

Christian tradition: Paul left Judaism and taught Gentiles a brand new religion and way of life.
