Greetings from the Mohonk Mountain House (www.mohonk.com) in the mountains of New York state. I am on a retreat run by the New Canaan Society (newcanaansociety.com), an evangelical men's group headquartered in, that's right, New Canaan, Connecticut.
I have been introduced to something called "freestyle" praise and worship. It can be moving, though in general I think it ought to be tempered by traditional devotion, i.e. to the Blessed Virgin, and to our Lord's sacramental Presence.
So far, I've heard talks on the transforming power of mercy, and something about "windows on the soul," both of which were pretty good. Sherry after High Mass is not to be scoffed at; but good old evangelicalism can remind one of what a blessing it can be actually to let oneself go a bit and get into some of the culturally lower forms of music.
