Pontificalia is an essential element of the religious circus. Without the fancy dress would Jesus-magic still enthrall the gullible, enthuse the pious and comfort the desolate? The showman needs his ensemble of silk and satin, his purple and gold livery, his dashing headgear, his rings, sashes and baubles. Such unworldly apparel is surely evidence of his divine calling, his proximity to the celestial throne and the Majesty of God Himself?
Then again, it might all be a charade, a masterful con-trick as old as the hills, a circus that the caesars found so useful, medieval clerics so enriching, and even the 21st century a spectacle so bewitching.
