I was always told, by several Christians, growing up that Jesus released Christians from adhering to Mosaic Law, but still upheld the spirit of it.
Always cited with;
Galatians 3:10-13
10 For all who rely on the works of the law are under a curse, as it is written: “Cursed is everyone who does not continue to do everything written in the Book of the Law.”[e] 11 Clearly no one who relies on the law is justified before God, because “the righteous will live by faith.”[f] 12 The law is not based on faith; on the contrary, it says, “The person who does these things will live by them.”[g] 13 Christ redeemed us from the curse of the law by becoming a curse for us, for it is written: “Cursed is everyone who is hung on a pole.”
