Catholics do not think of their traditions as the traditions of men. So your challenge doesn’t seem to address the issue. For us the issue is whether God is with the Church or not, and whether the Council at Jerusalem was right to say, “It seems good to the Holy Spirit and to us ....”
What matters is not what you or I or anyone else thinks. What matters is what God thinks.
The Lord is always with His church. Whether she reciprocates or not is a daily issue of the heart.
