It is all too easy and too simple to disdain as "superstition" everything one cannot understand, but the ancients themselves knew very well what they meant when they used symbolic language...the Spirit can always come back to breathe fresh life into the symbols and rites and give them back their lost meaning and the fullness of their original virtue.
I can't think of any way to explain the existence of art other than as a means to express something greater than ourselves. I can't reach a single musícal decision except wíth the goal of making a connectíon to God. If I separated the religious goal from the musical one, music would have no meaning for me.
