Did Christ assume a fallen human nature? "What is not assumed is not healed." So goes the Chalcedonian maxim articulated by Gregory of Nazianzus regarding the nature and extent of Christ's work in assuming a human nature. But what is the nature of that assumption? If Christ is to stand in solidarity with us, must he have assumed not merely a human nature, but specifically a fallen human nature? In Sinless Flesh: A Critique of Karl Barth's Fallen Christ, Rafael Bello argues against the assertion made by Karl Barth, T. F. Torrance, and those who follow them that Christ assumed a fallen nature. Through retrieval of patristic, medieval, and Reformed orthodox theologians, Bello argues that a proper understanding of human nature, trinitarian inseparable operations, and the habitual grace-grace of uniondistinction leads to the conclusion that the assertion that Christ assumed a fallen human nature is at odds with faithful theological and historical understandings of the incarnation. Readers interested in theological retrieval for issues in contemporary theology will find a faithful model and way forward for a thorny issue in modern dogmatics.
