Really, 52 Popes? The only one who counts is God.
The political maneuvers around AD 300-400 arrogantly labeled the Roman Bishop to the purportedly top lofty position. God was obviously not consulted. LOL. Nevertheless, the RC’s will never accept the more objective historical record unless God moves on their hearts and minds miraculously. And often, it just doesn’t seem to be God’s priority compared to other priorities for the individuals concerned.
