Christ also healed on the Sabbath (apparently, because we know Christ can do no wrong) breaking Levitical law. “Do you not know that the Sabbath was made for man, not man for the Sabbath?” It would not be the first time Christ set things on their head.
We have a new covenant and the old dietary laws were specifically done away with in the NT. And if the life is in the blood, then we have the life of Christ in us when we drink His blood at His command. I’m sorry, your argument does not hold water.
How does the ‘literal blood’ in the cup at catholic Eucharist get spread upon the Mercy Seat in the living Temple of God?
