It's pretty sad hearing non-Christians talk about Catholicism, Baptism, Methodism, Seventh Day Adventism, etc, as separate religions. It means that as Christians, we're failing dismally in our mission.
If we all believe in the same Holy Trinity, and the same Jesus, who died and rose again on the third day, loves everyone radically and unconditionally, and belief in whom is the only way to #Salvation, but we just have slightly different ways of expressing that belief, and slightly different styles of worship, then we're all Christians.
No denomination is better or more right or has more of the truth than any other. We need to stop fighting amongst ourselves, and start presenting a united front to the secular world.
