Association with Non-Christians; Judging Others

I wrote you in my letter not to associate with immoral people; I did not at all mean with the immoral people of this world, or with the covetous and swindlers, or with idolaters, for then you would have to go out of the world. But actually, I wrote to you not to associate with any so-called brother if he is an immoral person, or covetous, or an idolater, or a reviler, or a drunkard, or a swindler - not even to eat with such a one. For what have I to do with judging outsiders? Do you not judge those who are within the church? But those who are outside, God judges. Remove the wicked man from among yourselves. 1 Corinthians 5:9-13

Random thought: as I re-read this, I couldn't help remembering the case of Ms. Kessmann, until yesterday leader of Germany's protestants, who resigned in the wake of a drunk driving episode. Lots of people were declaring that she alone could make her decision, or that she should not resign. "The drunkard"... "remove the wicked man." Maybe God does think this is a bigger deal than some people would like to believe.

Nonetheless, my real reason for posting this were the themes of, "don't rip [sinners] for acting like [sinners]" (anybody ever read 1 John 3?), and "quit judging others - that's God's job."
