John Gray Quote

Christianity struck at the root of pagan tolerance of illusion. In claiming that there is only one true faith, it gave truth a supreme value it had not had before. It also made disbelief in the divine possible for the first time. The long-delayed consequence of Christian faith was an idolatry of truth that found its most complete expression in atheism. If we live in a world without gods, we have Christianity to thank for it.
