Papertyger, Thanks for the explanation. I do see what you are saying now and can somewhat agree.
BTW.... My “specific authorization from God” is the Holy Scriptures (the Bible) which is the living WORD of God.... nothing less and nothing more. And even there, I guess we have to account for possible mis-translations from the original manuscripts.
And don't forget all the doctrines that, despite the rhetoric, are NOT specifically, positively, enunciated in the Scriptures such as baptism.
Those divisions run long and deep, and show absolutely no sign of resolving themselves.
