Does all knowledge of God come through Christ alone, or can human beings discover truths about God philosophically? The Analogy of Being assembles essays by expert Catholic, Protestant, and Orthodox theologians to examine the relationship between divine revelation in the person of Jesus Christ and the philosophical capacities of natural reason. These essays were inspired by the lively, decades-long debate between Karl Barth and Erich Przywara, which was first sparked in 1932 when Barth wrote that the use of natural theology in Roman Catholic thinking was the invention of the Antichrist. The contributors to The Analogy of Being analyze and reflect on both sides of Barth and Przywaras spirited discourse, offering diverse responses to a controversy reaching to the very core of Christian faith and theology. It would be difficult to match the range and quality of commentators on this historic exchange between a Catholic philosopher and a renowned Reformed theologian on a subject of enduring significance, given the centrality of analogy to any issue in philosophical theology. Moreover, the contributions exhibit how the issues have come to span ecclesial boundaries as their import has progressively evolved. A splendid collection! David Burrell, C.S.C. Uganda Martyrs University A profound testimony to the enduring significance of the analogia entis debate between Erich Przywara and Karl Barth. Hans Boersma Regent College In a fresh ecumenical context, this extraordinary volume rekindles the mid-twentieth-century encounter between ressourcement thinkers and metaphysical theology.
