It is clear in the Bible that women are not to have leadership positions in the church, and in the home. It is very specific about the man being the "decider". However, the Bible also tells men to respect their wives.
For this specific question on whether this applies to teachers is up to individual denominations, and indeed, individual churches within denominations. I'll ask God later who is correct, because I certainly don't know.
To me, this seemed like a crappy thing to do to this lady, but it is up to her now to accept it or find another church.
She apparantly made a mistake 46 years ago, or whatever, about the doctrinal purity of the First. She shouldn't waste her time, patience or knowledge on such people. Just kick the dust from her feet and hat up!
