In some circles, yes, every Christian has an amazing amount of authority. People in my former church, Fundamentalist independent Baptist, felt perfectly comfortable in dismissing what any other person believed or taught if it disagreed with a personal interpretation. I often heard lines like “Well, he hasn’t read Whateverbook 14:3.” The only authority other than our verse slinging was saying the preacher didn’t believe that way. If we disagreed with out pastor, finding a verse to support our position was not too hard. You can prove pretty much anything if you use quotes absent context.
I suppose the ultimate proof is in how we hired pastors. An advertisement would be placed in a publication geared toward people with our belief system. A selection committee would invite finalists to preach on successive Sunday mornings. The committee would pick one to whom an offer would be made. If he accepted, the church would vote to ratify the hiring. Even though we were nominally Baptist, any potential pastor crossing the invisible lines of our own interpretation, even though it may fit with other Baptist churches, could forget hearing from the committee.
That said, any member of our church would think nothing of getting out a Scofield Bible, following the references, and thinking himself fully capable of discerning the full span of Christian faith.We never once heard a sermon about the origin of the Bible, so there was no fall-back on authority.
Going to Sunday School, Sunday morning preaching, Training Union, Sunday night service, Wednesday night service, and even to jail services, I never once thought about the origin of the Bible until I started talking to a priest. It was sort of a given that the Bible had been around since day one and that private interpretation was totally valid.
If you operate that way, with the Bible independent of its background, you really don’t know what has been believed past your own experiences. Truly, I had no idea how limited rapture theory is until I crossed the Tiber.
All my friends and relatives in my home town are at least culturally attached to the church where I grew up. If the topic of the end times comes up when I visit, some are very much surprised to hear that rapture theory is a historically recent development. They have never once heard that there is an alternative to that belief.
