Tracing John Webster’s later work on the doctrine of revelation provides a framework to answer both theological and philosophical issues regarding the doctrine. Theologians and philosophers have yet to agree on a myriad of overlapping issues, and epistemological and ontological questions surrounding revelation is of recent concern. “Revelation” in Christian theology is a multivalent term. In one sense, the term indicates an act of God, the economy of revelation, which describes how God reveals himself to his creation. In another sense, revelation is the content of that which God is communicating. Philosophical concerns arise concerning the ontology of revelation: Is it propositional, experiential, or some mix of the two? Epistemologically, if revelation has divine origins, how are non-divine beings like human persons able to apprehend the content of revelation considering its divine ontology? John Webster’s latest works trace both the economy of revelation and the substance of revelation in relation to the doctrines of inspiration and scripture. Webster approaches these questions as a theologian, but his careful method provides insight to the philosopher. We can construct a philosophy of revelation by tracing Webster’s theology of revelation and scripture, giving careful attention to Webster’s explication of God’s knowledge, God’s role as efficient cause in the economy of revelation, and the relation between revelation and Scripture. More common in Webster’s later works is the presence and reliance on post-reformed theologians and Thomas Aquinas which will give further precision in answering the philosopher’s questions concerning the ontology of revelation and the epistemological significance of revelation.
