Found this lovely little book which explains the different items proper to the dignity of prelates in the Catholic Church.
I think perhaps that one of the reasons we so dislike ceremony is that we must recollect ourselves. To remember the dignity of others, including ourselves, in solemn events. It's so much easier to dare others to despise our slouchiness, "Despise me, if you dare" than to take care of our manners of dress and addressing others.
Anyway, I had fun reading through this book.
