Did the Mosaic Law not also prohibit eating pork? But since we're no longer under the law we can now eat pork. Isn't it kinda the same thing? (it's like saying "since the Mosaic Law once prohibited pork we should still not eat it) Does that make sense?
I hear you and it is something to reason on. Regarding pork you might want to consider that it is notorious for having worms and being a health hazzard. So, the nation of Israel at that time, was governed by Jehovah and as a nation had entered into a covenant with him. The Law Covenant did give health regulations. I don’t think that not eating pork was a spiritual issue as much as a health issue and medical therapies were mostly rudimentary. These were things that made the nation of Israel different and likely healthier than the surrounding nations. In today’s world pork is mostly mass produced and generally isn’t as “wormy” as wild pork. But the tattoo in my opinion is more of a spiritual matter because it brands you. So, here are more sciptures that may help you.
Romans 12:1-2: “Therefore, I appeal to you by the compassions of God, brothers, to
present your bodies as a living sacrifice, holy and acceptable to God, a sacred service with your power of reason. And stop being molded by this system of things, but be transformed by making your mind over, so that you may prove to yourselves the good and acceptable and perfect will of God.”
1 Corinthians 10:31: “Therefore, whether you are eating or drinking or doing anything else,
do all things for God’s glory.“
