Ah so.
He makes no mention of seminary school or other training, so I'd only be guessing.
My wife's best friend is the daughter of a very strict Church of Christ (no musical instruments) preacher. She has suffered tremendously over the years, mostly verbally although when they were young there was a lot of physcial violence. It doesn't make the institution wrong, I know. But as the daughter of a very pompous man, she has put up with a heavier cross than the Lord gives to a lot of us.
Expectations are set very high for a PK. Add to that a father who's often dealing with other families' problems rather than his own, and it's perhaps no surprise that PKs often "go bad." And an overbearing father to boot... I am really sorry to hear this.
