Jews considered Gentiles to be unclean regardless of belief in God. The food laws still remain valid, as much as the 4th Commandment still remains valid. I covered this on page 9 of this thread already, though I don’t expect new people to the thread to read all the previous posts.
Yahushua did not do away with the Law, He said it Himself, (5:17-20). The Torah is our standard to live by, it teaches us what sin is (Romans 7:7). Yahushua had the penalty of breaking the Torah nailed to the upright pole, the penalty of separation from Yahuweh. He had the penalty nailed because it’s impossible for us to keep the Torah perfectly, this does not any way mean that we can disregard the Torah now.
The Law still stands! I have been crucified with Yahushua. Why? So that I might upright and sinless before God. Does this this mean I no longer sin? No, it just means God cannot see my sin. I am perfect in His eyes, He forgets my sin and remembers it no more (Isaiah 43:25). I am covered with the Spirit’s Garment. It allows me to stand before Him and be His friend.
His food laws are for our benefit, to help us live healthier lives.
Leviticus 19 lists a number of laws, for example do not hate your brother, do not steal, do not lie, do not deceive one another, respect his [read: your] mother and father, and you must observe my Sabbaths (4th Commandment, and mentioned twice in Leviticus 19). Then it comes to verse 28 which says “do not cut your bodies for the dead or put tattoo marks on yourselves.” To understand this we need to understand context. Though I’m not a Karaite I still think they provide some good insight into Torah, it’s not as heavy as what it seems to please read it if you get the chance. Pretty insightful stuff!
