If I had to choose one thing that has corrupted the Church in the United States, it would be government entanglement. I've written plenty here about the Catholic Campaign for Human Development (CCHD), but it's peanuts compared to Catholic Charities and Catholic Relief Services, both of which are knee deep in enabling government evil.
My friend Janet has a great post about Catholic Charities on her blog. It's a good reason to look for alternative charities that you know are solid. We have a non-negotiable responsibility to help Lazarus at the gate. We shouldn't have to finance government condom and needle exchange programs at the same time, not to mention enabling minors' abortions.
