As a non-denominational christian who's parents are catholic and I have been to numerous Catholic Services I could never imagine becoming catholic. I have been to Mennonite Services and Evangelicals, nothing seems to fit me but to me the most confusing and difficult to understand is catholicism, I do not understand how being a follower of Christ would require all the show and imagery the Catholics need.
But that's like saying all you need for a meal is crackers.
God is transcendant AND immanent.
They don't have them at the church I go to but I like the idea of a traditional Mass --- it's not just show and imagery, it's about "communion", --- something that unites Catholics of the present day with those of 200 years ago, 800 years ago, 1000 years ago. There's nothing like Frankencense, the Gregorian chants, gothic arches to makes you feel the presence of your religious ancestors. Maybe what looks like show and imagery is something like fireworks, flags, parades, and picnics on the 4th of July.
