Henri De Lubac played a major role in nearly all of the theological debates within Roman Catholicism during the twentieth century. Educated in the renewed Thomism of Blondel, Rousselot, and Marechal, he urged a return to the church fathers, cofounding Sources chretiennes, an important series of patristic texts with translations. The Discovery of God contains the guiding thread of all of de Lubac's work: the idea of God and the life of the spirit. In this important volume one finds the ultimate justification for de Lubac's positions against the atheism of East and West. The book stands as a gloss on this dictum of Thomas Aquinas: In every act of thought and will God is also thought and willed implicitly. Although his book provoked much controversy at the time of its original publications de Lubac insisted that its intention was simply to drawn on the double treasure of the philosophia perennis and Christian experience in order to lend a helping hand to a few people in their search for God.
