Hans Urs von Balthasar's discourse on the descent of Christ into hell and its implications for the Triune God have been disputed for half a century. One of the Trinity has Suffered evaluates and revises von Balthasar's theology of divine suffering in a way that interacts with and significantly enriches contemporary Catholic theology.

In this book, Joshua R. Brotherton engages twentieth-century Thomistic theology, as well as the thought of Pope Emeritus Benedict XVI (Joseph Ratzinger) and Pope St. John Paul II. Drawing from the vast secondary literature on von Balthasar, Brotherton offers a balanced assessment of his work on the topic of divine suffering, both critical and appreciative.

Recognizing von Balthasar's laudable attempt to integrate mystical spirituality and systematic theology, Brotherton seeks to distinguish valid insights from confused mixtures of metaphorical, meta-symbolic, and philosophical (metaphysical) discourse on God, particularly with respect to the classical problem of how the Creator who willed to become incarnate may be said to suffer. Truly, "One of the Trinity has suffered" and yet this mystery of faith must be carefully explained and understood in conformity with sustained Catholic reflection on divine immutability and simplicity, the dual nature and unique personhood of Christ, the Trinity of divine subsistent relations, the freedom of God in creating and becoming man, the analogy of being, the problem of evil, and the immensity and infinite value of Christ's redemptive suffering.
