So...your church does not teach that you have to follow the 10 commandments? Your church considers them the 10 strong suggestions? Are you an albigensian?
Actually, the Ten Commandments aren't the Old Law. Everything after them is (circumcision and such)
Jesus proclaimed the 10 Commandments. He even pointed out His favorite. I don't recall him doing the same about the laws for tatoos.
Nice try though. It may pay to read a little more.
