Christianity came from John, Paul, and Simon the stumbling stone (petros), their writings compared to the original church, established a cult mentality, of placing the followers under the charismatic leader.

Since the Muslims spent so long arguing with the Christianized cult mentality, they've become Muhammadans, instead of studying the world's religion as one.

Baha'i, Krishna Consciousness deifies its leader, and follows a cult mentality.

There are many religions that instead of being spiritually empowering, put the followers under some charismatic leader, instead of a direct connection to the divine.
