The higher Christian churches—where, if anywhere, I belong—come at God with an unwarranted air of professionalism, with authority and pomp, as though they knew what they were doing, as though people in themselves were an appropriate set of creatures to have dealings with God. I often think of the set pieces of liturgy as certain words which people have successfully addressed to God without their getting killed. In the high churches they saunter through the liturgy like Mohawks along a strand of scaffolding who have long since forgotten their danger. If God were to blast such a service to bits, the congregation would be, I believe, genuinely shocked. But in the low churches you expect it any minute. This is the beginning of wisdom.

Annie Dillard, Holy the Firm. Not sure I buy this take but it is thought-provoking.
