A good look at the Josephite movement will show a group of "organized" (man that term is evil, a necessary one though) believers that were far from self righteous. Most of them died for their faith, soon after the communist revolution in Russia. They are the unknown martyrs of their generation.

Secondly the Christian religion is based on infused righteousness. Anyone practicing self righteousness is at best worthy of discipline and at worst a lying hypocrite in the very eyes of organized religion.
