The writings of Scottish Reformed theologian Thomas F. Torrance suggest that Christian assumptions in the areas of God, creation, and humanity have had an important influence on the development of Western scientific culture. Persons, Powers and Pluralities develops each of these areas to articulate a theology of culture rooted in a Christian understanding of God as triune, creation as contingent, and human beings created in the image of God. Drawn together, these three strands suggest that human culture and cultural plurality ultimately originate in the creative action of a God who constitutes a trinity in unity.
Flett develops a theology of culture that is equally Trinitarian in nature and harmonious with, yet an extension to, Torrance's overall thesis. The result is not only a unique contribution to the emerging secondary material on Torrance's work, but a contribution in its own right to the field of theology of culture.
