I think the correct answers are No and No.
Under the law of Moses, tattooing the flesh was a violation of that covenant.
1. Israel was under that covenant, therefore the marking of the flesh was not sinful.
2. Those who were not Israel were not under that covenant, therefore the marking of the flesh was not sinful.
Those who partake of the New Covenant are not under the Old Covenant, but our law is love and faith.
3. Under the New Covenant, what is not of faith is sin. Is the marking of the flesh harming your neighbor? If not, then judge for yourself on your own conscience whether marking your flesh represents sin.
Love and faith? Aaawww that is nice...
Love like the world loves its pagan ways? Or like Buddhists or muslims love?...or LOVE AS HE LOVED US...
Have a faith like demons and Satan have that He is the Son of God crying LORD LORD or a NOT DEAD faith with works...His works...DOING the Will of His Father...
So...indeed WWJD?...get a tattoo?
What He demonstrated and taught was His last will and testament for us (those whosoever ya dig?)...signed by His blood and sealed by His death...and can NOT be changed after the death of the testator...
...no matter how badly you torture or twist Paul’s epistles to the goyim as if they were required ONLY 4 things right? 3 of which dealt with kosher laws...just to be able to fellowship and hear the rest of Moses read every Sabbath...
That you think love and faith is all you need means you heeded jewish fables...dont do that Titus 1:14
Slandering jews claimed the law was changed even abolished at the cross...Luke was clear that was jewish false witness...
