I'm not sure what his departure means, though. If it's a Jesuit publication aren't there many more where he came from?
If B16 is to restore the authority of Rome in America, I think he will have to pick something to make an example of.
The Jesuits are a reasonable place to start, but, as you point out, there are a lot of them, and many of them appear to share a commom purpose with Fr. Reeves.
Can the pope inhibit or discipline the whole Jesuit order in some way?
