Hello everyone!
I've recently been punchsucked into the spn fandom again and I'm looking for a quite old fanfiction I think I red on fanfiction.net (or AO3?) some time ago. It was an AU, destiel, and Castiel was a highly devoted priest who tried to save Dean (a young hooker) from perdition.
I don't really remember everything about the fic, but I can tell there was an exchange between Cas and Dean somewhere at the beginning of the story, in which Cas told Dean in a confessional something like "Son, that's your problem: you have no faith." To which Dean replied "How could I acquire faith? Faith is a gift, isn't it? I have no faith because it wasn't given to me, so were is my guilt?".
I know it's not much to work with, I'm really sorry. ;_; But I hope someone will remember this particular story.
Thank you in advance for everything.  (´ ▽｀).。ｏ♡
