I think I had more than my fair share of bad seminary teachers. Maybe it is a problem worldwide; one was a professional seminary teacher in Utah and one was just a lady called from the ward when I lived overseas.
First of all, shouldn't the fact that there are professional seminary teachers raise a red flag? I'm not saying it's priestcraft, but it's probably the closest thing we've got to it. I guess the Church justifies it by paying these teachers as little as possible. It can't be priestcraft if the teachers are mending their pants with duct tape and shopping at the Bishop's Warehouse.
Anyway, this professional seminary teacher, let's call him Brother Duncan, was a very nice guy. He had just returned from his mission and was still in that super-excited mode. Unfortunately, he also was super-credulous and taught us every Mormon Legend story ever photocopied by an Elder as God's revealed word.
Seriously. I just found out last month that Red Robe Jesus is NOT a spitting image of the Savior, Japanese fighter pilots did NOT try to bomb the Hawaiian temple, and God did NOT destroy a laundry for displaying garments. Ok, I knew that last one had to be fake, but still. The disturbing part of this is that we were 14- and 15-year-old kids and these outlandish tales were presented to us not as stories, but as facts and in the same breath as our Old Testament reading.
These are just some of the better-known legends. He told us dozens more that haven't yet been debunked on a website. I have to admit that I felt a little betrayed when I discovered how full of it he had been.
I don't blame Brother Duncan (well, maybe a little); he just let his enthusiasm get the better of what little judgment he had. But why put someone so green in charge of hundreds of kids, and then even pay him for it? It just doesn't make any sense.
