Crap. I thought I'd answered all of them. Sure they can be used by God. God used a donkey. But according to scripture we're to remove them. These are so simple.
I think my typo may have misled you. The question was not whether some sick pervert priest can be used as an agent of God but whether you can be. And whether that means that you are perfect and free from sin.

Sure I can be. God used a donkey. And if God wants to see me as perfect and free from sin who am I to kick against the goads? But if I'm (God forbid) pokin' a 12 year old I expect to be delivered over to Satan for the destruction of the flesh so that my sould will someday be saved. Being turned over doesn't mean doing a communion service and delivering a sermon.
