Here's what can happen.
First, one of them starts a discussion about something theocraptic. Of course, at first it goes smoothly. But in time, they run into something that the Filthful and Disgraceful Slavebugger was not totally clear about. A heated argument ensues, and is ultimately settled when someone actually thinks. The solution goes against the Filthful and Disgraceful Slavebugger, but is totally in line with what the Bible actually says.
Now, when they go about their businesses, they are going to spread this "apostate" material into the congregations. People in the congregations are going to have to think, and eventually it will become transparent that there is a discrepency between what the hounder-hounder is now teaching and what the Filthful and Disgraceful Slavebugger wants them to teach. Result: More apostasy.
