 Some Christian commentators have sought to identify a similar middle ground by acknowledging that Christian categories, and the Christian liturgy, are likely to be experienced as strange or even alien by many in modern western societies. The evangelisation of such people may well depend then, in the first instance, not so much upon exposure to specifically Christian concepts as upon experiences of transcendence mediated through encounters with the beauty or majesty of the natural world, or of church or other buildings. These experiences serve then as a propaedeutic for Christian teaching. (Compare Brown 2004, pp. 407–408.)
