People do not understand what you call the sacred mystery...Otherwise there is no mystery...Some just accept it because they are told to believe it...Most don't believe it but accept it as part of the bigger religious propaganda...
But you are right...without the pomp there would be no draw to the Catholic religion...
Life itself is a mystery.
Of course people do not understand it. There is no propoganda involved unless one considers the bible to be propoganda?
