Jesus is the leader of the TRUE church--His rule in the hearts and minds of those who put their faith and trust in Jesus Christ and His finished work on the cross ONLY for their salvation, great and free. Not in your popes, membership in your church, or in Mary.
The main problem with YOUR argument is that YOUR church no more dates back to Jesus Christ and the Apostles than the Mormon church does! That is a lie your church has arrogantly declared for centuries! But we who know history know better!
