God & spiritual anthropology

A central problem with arguments like that of Charles Taylor's in A Secular Age can be put like this: if man has an inherent appetite for God and transcendence, how come we (i.e. man) lost him (i.e. God)? It follows that, if we are to accept a spiritual anthropology that assumes mankind's hunger for the transcendent, the story of human secularization can only be told coherently from God's side not from man's. It needs to be told as God's plot for man.
And so it must belong theology, not to historical sociology. And a strictly theological account of secularization can only be in dialogue with secular thought, if at all, under strict limits since it needs to believe, against reason and the evidence, in a God who actively concerns himself with man.
