There was a point in the 60s (I believe) when church architecture in the Delta changed radically. It was, to me, the equivalent of fins on Chryslers and Cadillacs. Rejecting the gothic stretch to the sky, a whole series of "modern" looking buildings with their low roof lines and toy spires were enthusiasitcally adopted by many of the main line churches. The Pentacostals and some other denominations continue this trend of the "modern".
