Eating pork IS a sin. Then Paul came around and altered the eternal Word of God which is meant to be ETERNAL and unchanging in any way shape or form.
****Then Paul came around and altered the eternal Word of God****
It was Peter who had the vision in Acts.
Actually, if you read Acts you will see that it was a vision of Peter that led to this change.
Paul didn’t change the Word of God. Did he rewrite Leviticus? Nope. He had a vision, a revelation, and he passed that on to us, as prophets are often instructed to do.
When Noah and his family were given a concession to eat meat after the flood, did Noah change the word of God? Or did God see fit to change what laws he held them to? Is that not within the purview of God? Is His sovereignty limited in that respect? If so, who has placed that limit on Him?
