"It's about the Benjamins, not about Christ."
Unfortunately thats the way it is in many churches and not just PCUSA. Churches are made up of people and people generally suck. In this case the PCUSA denomination keeps ministers from leaving by holding them hostage financially.
Other stats that are depressing are roughly 2/3rds of ministers in general don't beleive Jesus is the Son of God. Somewhere around there also don't necessarily beleive the Bible is the pure word of God.
These people generally became ministers because they wanted to help people and not because of their faith.
I find this oddly reassuring. I *had* been afraid that the local minister was a glib, personable, closet anti-semite. Now I see him as a somewhat pitiful figure, beholden to the folks who'll authorize his pension.
