I think perhaps the better question might be liturgical Christians versus non-liturgical Christians. An evangelical Anglican priest pointed out to me once, that for all the talk by the non-liturgical lot about how they focus on the Bible more, we liturgical Christians generally have much lengthier Scripture readings at our services. It’s gone even more in that direction with the happy-clappy movement coming in.
The newer Roman liturgy, as well as the Church of England’s ‘Common Worship’, typically have an Old Testament reading, an Epistle and a Gospel, as well as a Psalm read before the Eucharist is celebrated. I went to a rock and roll church down the road and they have one very short reading, an admittedly very good 10 minute sermon expounding on it, a few prayers (I was literally the only person in the room to join the preacher in saying the Lord’s Prayer) and 40 minutes of Christian rock music, with people swaying in the aisles and what have you.
I have to say that I was treated very kindly by these people and all my dealings with them have been very pleasant. But it’s about as far removed from my style of worship as can be.
