Don't bring over into the new testament laws and commandments that were not carried over to the new testament. Back up your facts with scripture from the new testament. As I already said, Jesus did give a new commandment not to kill, not to kill ANYONE, but to love even your enemies. Where is the scripture please that overrides the cutting of the skin & marking of the body? I would like to read that.
Rom 13:8 Owe no one anything, except to love each other, for the one who loves another has fulfilled the law. 9 For the commandments, “You shall not commit adultery, You shall not murder, You shall not steal, You shall not covet,” and any other commandment, are summed up in this word: “You shall love your neighbor as yourself.” 10 Love does no wrong to a neighbor; therefore love is the fulfilling of the law.
