As a seminary teacher and one who is very aware of church history warts (or potential warts) I try to teach in such a way that the students become aware of these things in a normal, comfortable manner. Last week I taught the translation process and no one batted an eye when I mentioned the above translation fact. Now, if someone tries to blindside them in the future this fact in a faith discouraging manner, they will already know and be prepared. While working on one of next week's lessons, I came across the following verse that never stood out to me like it did today and relates well to this issue.
D&C 38:30 I tell you these things because of your prayers; wherefore, treasure up wisdom in your bosoms, lest the wickedness of men reveal these things unto you by their wickedness, in a manner which shall speak in your ears with a voice louder than that which shall shake the earth; but if ye are prepared ye shall not fear.
I feel bad for those whose church history learning was out of sync and created some cognitive dissonance for them when the more accurate information was learned. I know I've been there a time or two.
