The Athanasian Creed

What could have been more appropriate for Trinity Sunday than the Athanasian Creed? That's what our second candidate gave us -- a copy (not in this format and capitalized differently) passed out with the bulletin, and recited before the sermon. We're quite familiar with the Apostles' and Nicene Creeds, but I think this is the first time I've read the Athanasian Creed.
