The food laws were never done away with in Mark 7. That is a misunderstanding. Messiah was rebuking a HAND WASHING ordinance added to the Torah (this is a dogma)...Dogma is what Paul is referring to as abolished. Not the law, which Messiah clearly said he did not come to destroy (Matthew 5:17-20)...If what Narkosiss says is true, then Messiah was breaking down law when he said he didn't come to do so! He was breaking down traditions of men in Mark 7! Not God's laws... This is proved by the fact that by the time Peter in Acts 10 is told to "Kill and eat" he REJECTS the false idea, and is in the right in doing so! The message was not about food, but PEOPLE... (Acts 10:28)...
Paul still says that there are UNCLEAN things (2nd Corinthians 6:17) which goes along perfectly with Isaiah 65 and 66 which teach of the prophecy of false teachers who claim the law is done, and eat swine.
Shalom
