And that may be the real tragedy. That compounds the problem. If persons know they're not thinking Christianly, then they know to take the time to learn to think Christianly. But if they don't even know the difference, the educational task becomes immense. And that is precisely the immense challenge that biblically literate pastors face in teaching their congregations.
Some pastors are, by self-designation, Bible teachers.
I applaud them. I admire them. The goal of a Bible teacher is for a student to know the Bible. Quite challenging, much of the time. But unfortunately, the distinctions are not always as clear as the Jerusalem-Babylonian distinction.
