Don't they keep a big repository of saints that each require at least two miracles to be considered saints?

EDIT: yes http://en.wikipedia.org/wiki/Canonization

> To be canonized a saint, at least two miracles must have been performed through the saint's intercession after his or her death

Doesn't matter if they're Catholic, Hindu, Muslim or whatever. This is religious fanaticism at its best.

The difference with Catholicism being that it has one indisputable leader.

Mostly indisputable. :-)

Which lead to mutual excommunication(as these things usually go).

"I don't remember Catholics being eager on self-proclaimed wonders."

Isn't seeing images of Jesus in toast and other silly stuff like that somewhat common? I feel like I see that kind of thing in the news in _America_ from time to time typically associated with Catholicism.

Very of those few are taken seriously by anyone. The Vatican is supposed to confirm miracles, and from what I remember it's not exactly an efficient or easy process. In this case I sincerely doubt they'd call it a miracle.
