Mossa, a Jesuit steering toward ordination in 2008, hosts the You Duped Me Lord blog. I keep meaning to ask him about that blog name...
Update: He left an explanation in the comments, which I'm bumping up here:
Check out Jeremiah 20 in the New American Bible translation. That's where the name comes from. I love it because expresses the frustrating and wonderful truth about vocation that it never is quite what you imagined it would be, because God knows that if he told you what was going to happen, you probably wouldn't have done it. We have to grow into our vocations, and sometimes we might get a little angry at God in the process! But read on in that chapter and you'll see that Jeremiah has been inescapably captured by God in spite of everything. I can relate.
