I think we need to be careful not to get caught up in “experiences.” ANY “experience” becomes routine after repeated exposure, causing the person to seek more fulfilling “experiences.” That’s one reason why Catholics convert to Protestantism, and why Protestants do the “church hop” searching for better churches–because they are seeking a more transcendent “experience” of God.
I think it’s important that we constantly remind ourselves and others that we walk by faith, not sight (or “experience”). God is just as real in a boring Mass as He is in an ethereal, beautiful, inspiring Mass.
That being said, I do believe that it’s a noble goal to try to make our Masses more appealing by bringing in “excellent” music of all styles, training our priests to be better homilists, creating a more uplifting architecture, making sure that the worship space is physically comfortable (not too cold or hot), making sure that the worship space sound system enables everyone to clearly hear what is being said or sung, etc.
I’ve said it many times on CAF–we do not cease to be human beings when we are at Mass. Human beings respond to those things that are perceived through their senses–a beautiful hymn, a clearly-heard and understood Scripture reading, a riveting homily, inspiring works of art, a comfortable seat, the appropriate temperature, etc.
There are certainly times in life where we should practice “mortification of the flesh” so that we can free ourselves from the “need” to have pretty music, exciting homilies, etc. There is great value in sitting through a “boring” Mass because it helps us to recognize that we walk by faith, and that our lack of an uplifting “experience” is not a measure of Christ’s True Presence.
But I think as a general rule, we should strive to make our Masses as appealing to frail human beings as we can. There is certainly no “sin” in offering up excellent music, a beautiful worship space, proper temperature in the room, etc. And these “human” things really do help many people to recognize that Jesus is Truly Present.
