Book excerpt: The Prologue of the Gospel of John identifies Jesus Christ as the eternal Word or Logos of the Father, who became flesh for the salvation of the world. Yet the world that Christ saves is his world from the beginning, for he is also the Logos of creation, the one “through whom all things were made” (John 1:3). This divinely revealed claim has profound implications not only for theology but also for metaphysics, whose relation to Christian doctrine was undermined over the course of the twentieth century, such that the Christian faith has become an increasingly private affair rather than a credible account of reality and an invitation to participate more fully in it. With Christ, the Logos of Creation, John Betz seeks to recover a Christ-centered, analogical metaphysics and to establish the indispensability of such metaphysics for Christian theology and the Christian vision of reality. In Part I, he dispels the fog of confusion about analogical metaphysics and addresses the ecumenical issues posed by Karl Barth’s famous rejection of the analogia entis. Part II demonstrates how analogical metaphysics helps to explain Christian doctrine and sheds new light on the interrelationship between individual doctrines, including Trinitarian theology, Christology and soteriology, and theological anthropology. In Part III, Betz explores how this analogical perspective can aid in resolving a number of theological disputes, including the metaphysical relationship between nature and grace and the issue of divine humility. Finally, Part IV outlines further directions toward a fully Christological metaphysics that is proportionate both to the challenges of modern theology and the reality of our life in Christ the Logos.
