I have had correspondence with a woman whose family left our church recently. I wrote to express that I missed them and hoped they had landed in a good place. They have landed in place I know a little about, and most of what I do know is not good. They were very big on being nearly a King James only church, allowing other translations for devotional purposes, "but not recommended for study." They had a scandal of badly mistreating an underage girl who had had sex with one of the pillars of the church (a deacon? a pastor? I don't recall), so that she ended up being blamed equally with him, and over time, more than him. I have known about a dozen people who went there - more than half of them were quite decent folks, but four were difficult, accusing sorts who could find no good in any congregation but their own, and not much of that. Hectoring sorts.
That data is all a decade old or more, so perhaps things have moderated there. She did make a comment much like one I have heard for years. "They really get into the Bible there during service, not just reading it off the screen in front." (Our current church puts the scriptures for the day up on the screens.)
Ah yes. The preacher says at those churches. I WANT you to bring your Bibles to church. I WANT you to look up the verses that I'm using so that you know we're not trying to deceive you here. You'll see that we are only preaching what it says right there in Scripture. You can see it for yourself. I expect to be held to account.
It is a deceptive practice. I am not doubting the sincerity of the preacher in saying this. He in all likelihood deceiving himself as much as his hearers. Yet no one has ever questioned for a moment that he might be switching the words around or putting in verses that aren't there. I daresay he has never been to such a church nor heard a credible report of one. The issue is that what he believes is "just what the plain meaning of Scripture is" is in fact the product of a hundred assumptions he does not know he is making. While having people follow along might spark their attentiveness and cause them to notice what they otherwise might have missed, I think it more often dulls this sense. The mechanics of getting to the page and verse, of listening and reading at the same time, and the automatic brief reflection on what has just been said conflicting with paying attention to the current sentence all work to prevent objective thought.
At the very moment when the listeners are most at the mercy of the preacher the preacher is telling them they are most independent of him. They have the illusion of checking his work when they are in fact swallowing it whole. He might as well ask them to prove his doctrine by checking his spelling.
