A crisis of faith is a personal thing, and really nobody else's business. Mother Teresa did what she did, and if others stuck her on some kind of pedestal, is that her fault?

Don't know what Catholics teach about saints, but from what I know about them, a great many of them had backgrounds that were anything but admirable, and their redemption and humility in the face of it was a large part of their makeup.

Saul of Tarsus comes to mind.

The underlying theme of Christianity, if it's anything, is that it's the sick who need the physician the most. Others may have put Mother Teresa on that pedestal, but I'm sure that's not how she viewed herself.
