I've read St. Thomas Aquinas' theology and philosophy, but I've never stopped to wonder why he's considered a saint. I probably assumed that being the prolific and influential writer he was, establishing the basic conceptual foundations of Catholicism and thereby becoming one of the Doctors of the Church, was probably justification enough to endow him with such a title.
As it turns out, I was wrong. Being the Church's greatest theologian and philosopher of all time is not quite enough to get you to party with Jesus. For that, it seems, you need some incontrovertible evidence of a miracle, and if the following story doesn't convince you we're dealing with real transcendence here, I don't know what will :)
Of course, Aquinas should have been worshiping Mithras, not Jesus...
