Not defending tattoos and dont have any but Im a Christian and not under Levitical law either. You sort of quoted Leviticus 19 v. 28 did you read and do you obey Leviticus 19 v. 19?
Ye shall keep my statutes. Thou shalt not let thy cattle gender with a diverse kind: thou shalt not sow thy field with mingled seed: neither shall a garment mingled of linen and woollen come upon thee.
Or the Levitical law that says that you must build a battlement on your roof to keep people from falling off? Were you and your male children circumcised on the 8th day after being born?
