Writing in the London Review of Books, Keith Thomas says of sacred space and the Church:
All these practices presuppose that divinity is immanent in the world, but in a localized way. The demarcation and protection of holy spaces becomes one of the means by which religious institutions assert their claim to supernatural authority. It is, therefore, all the more remarkable that the first Christians should have rejected the whole notion of sacred space. Whereas the Greek and Roman world had been full of holy places, the early Christians were encouraged to see themselves, not buildings or sanctuaries, as the temple of the living God (II Corinthians 6.16). For them, God was ubiquitous, rather than located in some particular spot. Only in the fourth century did Christians begin to construct their own sacred topography. The driving force as the cult of the martyrs and the building of urban churches to contain their relics. It set in motion a long process by which Catholic Christianity would construct a new geography of the sacred.
This same glorification of space still exists in Protestant circles with regard to Jerusalem, the “Holy City” which is thought of as somehow closer to God than Ames, Iowa or anywhere else. The fact is that all the land is now sacred.
