Christianity was the basis of European civilization, and now it is dead save for a remnant smaller than mustard seed. Civilizations die with their animating religion, being devoured by demons.As with other topics, we have plowed this ground before:
Progressivism wears the religions it has devoured like a monster that dresses itself in the skins of people it has eaten. It has consumed Judaism, Christianity, and most of Islam, though the worst and most harmful religion, Islam, still lives and is fighting back. The martial Christianity of Charles the Hammer would serve our civilization well. The pragmatic, realistic, and cynical Christianity of restoration Anglicanism would serve our civilization very well, though it proved vulnerable to people whose beliefs were dangerously sincere, being reluctant to martyr them properly for reasons of mere pragmatism. Counter Reformation Catholicism would serve our civilization well. But none of these live, and their revival is unlikely.
Traditionalism's unprincipled exception
Christians, like most redoubts of like-minded people, are generally not self-aware. What is to us our touch with the metaphysical is to others empty ritual, archaic and useless in technological society, or antithetical to their own traditions. Having been rebuffed by their atheist, Jewish, Muslim, and Mormon neighbors, Christians look wistfully to the cultural followers of Africa in fulfillment of the Great Commission. As the Radix essay points out, Christians, from conservative "Anglicans" fleeing cultural relativism to Protestant liberals handing out counterproductive foreign aid, use Africa as a totem to compensate for the death of faith and lack of moral urgency in the West.
My message on this is known to readers, and is banned on Christian blogs elsewhere: time for the Church to feed Her sheep.
