There have been so many "splits" in the Baptist Church, the Reformed Church, the Presbyterian Church, the Methodist Church, <insert other churches>

These have all gone through huge upheavals when something as controversial as letting women have their hair down. Or letting Gay/lesbian members participate in service proceeding (communion in one case). Or just acknowledging that Gays/Lesbian exist and need help...

Simply stated, it only takes one preacher/priest/pastor taking offense/exception and steering his congregation to split and form a new branch of the church
