Maybe this is where I first gained an appreciation for religious art. In my home town there were lots of outdoor statues of the Virgin Mary. They pretty much looked exactly like this one from Flatbush Gardener's blog. But What I love here is the flower garland. It shows such devotion on the part of the owner. And the plexi-glass protecting her too.
I grew up in a "low-church" Episcopal church in New England. There was very little decoration. Just two stained glass windows, all the rest were plain glass. That suited my parents just fine, who are both "made very uncomfortable by the 'high church' services that I attend" (their words).
I don't know enough about liturgy yet to be able to speak meaningfully on the subject. All I can say is that I like what I perceive to be the more emotional-ness of the church I attend now. There is more movement, music, color, sounds, and yes, even smells (smells and bells). But what I really enjoy is being surrounded each Sunday by such amazing religious art. I understand on a deeper level the love, suffering and awesomeness of God.
