Some interesting notes on this thread.
First, I apologize to Korean-American Christian for labeling him KAH. I have no idea how this was so solidly stuck in my mind.
Second, the only mandates and conditions and doctrines--unmarried clergy, abstaining from meat on Friday, for instance, have only been in place for the Roman Catholic Church. If anyone is interested in starting their own church, then there will have to be some rules put down. I hope that nobody tries to use any unbiblical doctrines to their rules.
Although I do know that several of such "do it yourself" churches have started, which mandate the use of King James Bible ONLY. And then there are the churches that while quoted in Scripture, do not use the quoted verses in context, but make it a demonic doctrine, such as snake handlers and such. Or the "Old Believers" of Russia that will not bury a man unless he has a full beard. Or the churches that forbid women to even speak in a church building, and they must wear skirts down to their ankles. I've been to more than a few churches in my years, and I have seen these things and many more.
Even some of the mainstream churches are using "Creator, Redeemer and Sanctifier" as the name of the Holy Trinity, instead of "Father, Son, and Holy Spirit," and that baptize adults in the name of the Father, the Son, and the Holy Spirit, the Lord Jesus Christ. Neither of these are Biblically correct. Here is the correct formula:“Go ye therefore, and teach all nations, baptizing them in the name of the Father, and of the Son, and of the Holy Ghost:” Mat 28:19.
It's not just Roman Catholics have a few (or many) "doctrines of demons"
