The prohibition against making a tatoo applies to Jews. If you’re not Jewish, tatoo away!
Yes, I have read that opinion before by Albert Mohler Jr., president of The (SBC) Southern Baptist Theological Seminary in Louisville, KY, about the 600+ laws in the OT. And I remember reading in the NT the debate among the 12 disciples whether gentile males would have to submit to adult circumcision in order to become Jew/Christian. I guess the 10 Commandments don't fall in this category of Jewish law since they were passed directly to Moses by the heavenly Father?
