I have ZERO tattoos. Not one. I’m 50 and spent 32 years in the military. However, I also know the difference between Judaism and Grace and what Paul preached. I know there were some in the early church trying to throw brothers and sisters under the yoke of the law that didn’t apply - and the Jerusalem council was VERY specific as to what they could NOT do...and Paul was very specific as to what applied to Gentiles and what did not.
We are under grace but that does not invalidate the law.
