In his blog, Pastor Tullian Tchividjian wrote this,
The only way to musically communicate God’s timeless activity in the life of the church is to blend the best of the past with the best of the present. In other words, we must remember in our worship that while “contemporary only” people operate with their heads fixed frontwards, never looking over their shoulder at the stock from which they have come, and “traditional only” people operate with their heads on backwards, romanticizing about the past and always wanting to go back, the Church, in contrast from both extremes, is called upon to be a people with swiveling heads: learning from the past, living in the present, and looking to the future. That’s the only way to avoid in worship what C.S. Lewis called “chronological snobbery.”
