This article reviews the late Colin Gunton’s Trinitarian engagement of creation and culture in The One, the Three and the Many. The thread which runs through the book as a whole is, as the title suggests, the problem of the one and the many—a problem that had its source in ancient Greek philosophy in the conflict between the Heraclitean and Parmenidean descriptions of the “real.” For Gunton, the concept of the Trinity provides relational space to mediate between the One, championed in classical times by Parmenides, and the Many, championed historically by Heraclitus. Gunton does not make a convincing case for claiming that the overarching influence of the Parmenidean account of the One inevitably leads to political absolutism. The solution to political absolutism is to move past a Parmenidean view of God as beyond knowing and toward the knowledge of God rooted in Jesus Christ, for where God is truly known in Jesus Christ, there a leveling process occurs. In the course of discussion, consideration is also given to Gunton’s theological methodology and use of terms like perichoresis, hypostasis and sociality in context, which he terms “open transcendentals.” Originally presented to the Reformed Theology and History Group at the American Academy of Religion Annual Meeting in Atlanta, Georgia, November 2003, the essay evaluates as well Gunton’s contribution to Reformed theology and his enduring significance for the theological enterprise. Here it is claimed that Gunton’s legacy for Reformed theology has less to do with his doctrinal proposals than it does with his theological style.
