For some reason this popped into mind.
Charlie Brown: I think there must be something wrong with me, Linus. Christmas is coming, but I'm not happy. I don't feel the way I'm supposed to feel.
Charlie Brown: I just don't understand Christmas, I guess. I like getting presents and sending Christmas cards and decorating trees and all that, but I'm still not happy. I always end up feeling depressed.
Linus Van Pelt: Charlie Brown, you're the only person I know who can take a wonderful season like Christmas and turn it into a problem. Maybe Lucy's right. Of all the Charlie Browns in the world, you're the Charlie Browniest.

Catholics can take a wonderful passage like John 20:31 and become Charlie Brown.
And they ALWAYS seem to fall for Lucy when she jerks the football of salvation away from them each time.
