‘We shall be like him,for we shall see him’: Augustine's De Trinitate and the Purification of the Mind

Contemporary re‐examinations of Augustine's De Trinitate have made the case for the coherence and consistency of the work based on the material content of its trinitarian theology. I propose that Augustine's understanding of De Trinitate's function also ties the work together as a whole. Rather than just talking about purification, De Trinitate attempts to participate in and correspond to God's economically grounded, eschatological purification of humanity. By undertaking a close reading of Book 1, followed by a brief overview of Books 2–15, I make the case that reading De Trinitate as a participation in purification holds all 15 books together.
