The "Ten Commandments" (`Aseret HaDibberot) do not and have never applied to non-Jews, who are bound by the Seven Noachide Laws.
We Christians ...are grafted in to the root... of the teaching about god ,His commandments, His instructions on how to live an obedient life to please Him: (being God’s covenants, promises and Jesus (the expected Messiah)fulfilled the law, and brought liberty by His Spirit.
We honor and love the whole Bible. It is the Word of God.
Have you read the New Testament? Read it for yourself and find the lies, distortions, false teaching in it ... (there aren’t any). Not a light reading with an already made up mind. Rather a thoughtful study of the old testament Torah along side it.
Peace. May God be with you. Sorry this may not be as clear as I intended. Huge subject.
