It takes courage to be a considered atheist. Many of us are agnostic in that we don't want to be troubled by issues of faith too often, but it seems that relatively few people are prepared to abandon altogether a belief in something divine. We are more comfortable even with the possibility of a malevolent god,  than of no god. 

So you have to commend this person for her outlook, and for working for a non-faith-based movement or meeting place. Still, are the United Church people in the wrong for saying that she cannot represent their church?
