I think it's one of
these. But can't be sure.
Absolutely not. That's slanderous (not libelous because this is not exactly print). When I went to a Christian school I was not only educated by their books, I was at a level far beyond my peers in the equivalent grade in public school.
Any idiot can tell that's fake because of the incorrect word usage (weather/whether) in the grammar section.
The Bob Jones University books were bad though. I remember a "Bible Truths" book in Bible class and the worksheet from one one lesson basically just tested weather (see what I did there?) or not you memorized the lesson word for word. "Jesus says that blank should blank, blank, blank, and blank." Ugh. I think my BJU science book also said that lemmings commit suicide on lemming runs.
