This is the Body of Christ, this teaching is "the flesh" of Jesus. No one who does not fulfill the law as Jesus did can have the life promised for compliance in them. "Unless you eat my flesh you can have no life in you."
The subject of Kosher law is not about food. Thats what Jesus was referring to when he said "eat my flesh".
The Law doesn't prevent anyone from doing anything but does warn that if you eat the flesh of unclean creatures that DO NOT RUMINATE you will surely die the death and devolve into an unclean creature that can't RUMINATE.
Same goes for bottom feeders, wolves, vultures, parasites, worms, talking serpents, dogs, teeming vermin who go down on all fours, creepy things that creep, are equivalent to narcissists, sadists, thieves, liars, sorcerers, scumbags, hypocrites, etc. All the creatures described whether clean or unclean represent human archetypes.
Its not rocket science. Kosher law can be summed up by saying if you fill your head with garbage it will defile and contaminate your mind, the seat of your conscious existence and experience of life, and you will die, go insane.
