How can the Church speak of the God who transcends all thought and speech? This book is a comprehensive retrieval of Thomas Aquinas's theological epistemology of the divine names, which is his profound contribution to that perennial question. His theology of the divine names is a rich and complex tapestry that weaves together the twin themes of negative and positive theology. Tempering any extreme agnosticism, Aquinas sets out a multi-layered negative theology respectful of God's incomprehensibility, while he also proposes a view of theological analogy that places it at the heart of his positive theology. Finally, he grounds his epistemology in the fundamental theological truth that God is the infinitely perfect and self-subsistence Creator.

Gregory Rocca's nuanced discussion prevents Aquinas's thought from being capsulised in familiar slogans and is an antidote to unilateralist or monochrome views about God-talk. Rocca laces Aquinas's negative and positive theology together, because only that intertwining can do justice to the mystery of God. This study finds that, contrary to the views of some, Aquinas's analogy is more a matter of judgement and truth than of concept and meaning; despite his own presuppositions, Aquinas bases his theological analogy more on the insights of faith than those of reason.

Aquinas's theology of the divine names encourages contemporary dialogue to keep the tensioned truth of God in view and to remember that only a fruitful interplay of positive and negative theology can do justice to the Elusive One who evades our linguistic capture and yet desires to be acknowledged and worshipped as Creator and Sustainer. The book will prove helpful to specialists in Aquinas and to others who are interested in the God-talk dialogue and can profit from an in-depth retrieval of Aquinas.
