In this superb volume, Troconis serves as a true guide to Ratzinger's highly nuanced, broadly sourced and intellectually complex writings. Her book is at once an accessible yet trenchant. It provides precise analyses of Ratzinger's works and spells out numerous implications of the themes of ontology, time, salvation and history with acumen. The book attends to key Christian doctrinal loci that have preoccupied Ratzinger, in dialogue with other modern theologians. An illuminating and persuasive study!
