He is unfortunately unclear on one point. He speaks of leaving quietly, without expounding on what he considers that to be. If he means slipping out the back door an disappearing, I'd disagree. If he means an orderly, non-disruptive departure, I'd agree. One should meet with leadership, confirm that there is a strong difference, and hopefully, if there is, the leadership would be able to suggest congregations closer to one's new views. And then quietly slip out the back door.
