The prohibition against eating blood stands OUTSIDE the Law.
It both pre and post dates it.
It is one of the FOUR commands given to the church at the Council at Jerusalem given by the Holy Spirit Himself.
The prohibition against eating blood has never been rescinded.
.
Only the eating of the fruit of the forbidden tree pre-dates the covenant law.
The saga of Cain and Abel demonstrates that fact well.
And how did Noah know which animals were “clean” 900 years later?
Many of those ‘blanks’ are filled in by Enoch.
.
Does the Catholic practice violate that prohibition?
When Christ said take and drink from this chalice, this IS MY BLOOD.....what do you suppose that He meant?????
