I suppose you think that mega-million-dollar-vomit-colored-monstrosity off the 101 freeway in Los Angeles is a "monument to Christ?"
That being said, I think you must admit that many of the European Cathedrals are on the gaudy side. This goes for protestant and catholic. But the fact that they were built did provide many people with job opportunities that they might not otherwise have had. But my hat is off to the people who built them and designed them rather than the people who ordered them built. They are, IMO, monuments to human acheivement.
