Baptist,Atheist,buddeist,Catholic,Mormon,Scientologest,Pentecostal,7th Day advent.These are some of the Religions of the world.If they were Christian's they would not have separate titles.There is no such thing as a Christian-Baptist and so forth.
These religions are created by men and women of the world.
Christianity is a Salvation and was not created by humankind.
As it is written:THERE IS NO OTHER NAME UNDER HEAVEN THAT IS GIVEN AMONG MEN WHEREBY WE MUST BE SAVED.
You can not claim the Christian name and another title of church worship at the same time.
