I was reading about Yom Kippur, and I came across this in a translation of the traditional recitation of the Kol Nidre: 

>"By the authority of the Court on High and by authority of the court down here, by the permission of One Who Is Everywhere and by the permission of this congregation, **we hold it lawful to pray with sinners**."

Isn't everyone a sinner?  If so, doesn't this mean that whenever you pray with other people, you are praying with sinners?  Is it not lawful to pray with sinners at other times?
