Within the parameters of the Christian tradition, humanity is to be seen as the height of God’s creation, whose life is shaped by the overwhelming radiance of the vision of God. The church is called into being through its apprehension of this vision of God, which it is called to pursue in its theology, spirituality, and ethics. Theology begins within this community of faith as it seeks to give an account of its communal beholding of the vision of God. Indeed, it could be argued that the supreme task of theology is to keep this sense of wonder alive as the process of unfolding the object of wonder and worship proceeds – in other words, as apprehension gives way to reflection and, supremely, the formulation of theory. The Christian community regards itself as being under an obligation to tell what it has seen, like the appointed observers at the great festivals of classical Greece. To behold is to report. Theory is an attempt to render in words the great wonders and mysteries of faith.
