The Council of Jerusalem is particularly troublesome for Rome as they relied upon Scripture for their ruling. They did not introduce anything new.
Of course, we have about sliced and diced the injunction against blood almost every way possible, yet Rome continues to insist otherwise.
The council also doesn't support Peter as being the pope as he was not in charge of the council.
I don’t even think Peter was head of the Jerusalem church. I think it was James, the half brother of Jesus, the son of Mary and Joseph. You know, the children of Mary and Joseph, that members of that other religion, think were his cousins. 😁
