From W. David O. Taylor, at this post:
It is a shame that conservative Protestantism exhibits such an allergic tendency to mystery. It is a shame that our corporate worship often makes the most minimal space for mystery. We prefer to hear sermons that explain things definitely. We like to sing songs whose meaning we can account for on rational grounds. The architectural and artistic shape of our sanctuaries, whatever they may be, err on the utilitarian side, and if symbols are employed they tend to be safe ones–that’s a fish, that’s a cup, that’s a flame. End of exchange.
