Jehovah Witness' are not regarded as a mainstream major Christian Church, Evangelical Churches are not all Literal Conservative in nature or considered a major unified Church either (many are only Churches in name, not in recognition) and Baptists, unless led by the resurgent Conservative Literalism are not Literalist either, ( there is a current schism in the SBC between liberal and conservative viewpoints)
There is significant difference between fundamentalist conservative literalism in American pastor led churches and what Spudbynight was referring to as Major Christian Faith.
Well that's the problem the minority churches think the mainstream churches are corrupt and don't reflect core Christian beliefs. The only true word is the literal word of god. And tbh I can see their point. You can't pick and choose what you believe because its convenient.
