Continuity, Naturalism, and Contingency: A Theology of Evolution Drawing on the Semiotics of C. S. Peirce and Trinitarian Thought

The starting point for this article is the question of the relationship between Darwinism and Christian theology. I suggest that evolutionary theory presents three broad issues of relevance to theology: the phenomena of continuity, naturalism, and contingency. In order to formulate a theological response to these issues I draw on the semiotics (theory of signs) and cosmology of the American philosopher Charles Sanders Peirce. Peirce developed a triadic theory of signs, underpinned by a threefold system of metaphysical categories. I propose a semiotic model of the Trinity based on Peirce's semiotics and categories. According to this model the sign‐processes (such as the genetic “code”) that are fundamental to life may be understood as vestiges of the Trinity in creation. I use the semiotic model to develop a theology of nature that addresses the issues raised by evolutionary theory. The semiotic model amounts to a proposal for a new metaphysical framework within which to understand the relationship between God and creation and between theology and science.
