The church has been an evolution of revelation. The catholics started the ball rolling, Luther exposed many of their false doctrines hence seperation from the catholic church. The baptists don't believe in speaking in tongues, or prophesy as the pentecostals do.
As god reveals his Word and reveals accordingly so must new branches of belief arise. Many new churches are opting out of the familiar denominational name tags.
I wouldn't be surprised to see churches in the future not preaching satan or hell and this would please me greatly.
As god has asked each person to discover that church where god would have them planted, and be faithful there and learn and edify and mature. God will work all the rest out to his glory and honor. The church has had a role to fulfill and has done well inspite of mans fleshly attempts to dominate and rule it and bad press from the unsaved without understanding.
We only know of what we experience. Churches around the world are completely different that the apathetic and laodecian type churches we get in "fat cat" north america. We think we are elite but we are not. Typically churches that are persecuted and oppressed have followers of such faith and dedication that would put 90% of north american believers to shame.
