Hilary of Poitiers (c300–368), who was instrumental in shaping the development of pro-Nicene theology in the West, combined two separate works, a treatise on faith (De Fide) and a treatise against the “Arians” (Adversus Arianos), to create De Trinitate; his chief theological contribution to the 4th-century Trinitarian debates. Scholars have long recognized the presence of these two treatises in Hilary's De Trinitate but have been unable to settle the questions of when and why Hilary did this. This book addresses these questions concerning the structure and chronology of De Trinitate by situating Hilary's treatise in its historical and theological context and offering a close reading of the text. It is argued that De Fide was written in 356 following Hilary's condemnation at the synod of Béziers and prior to receiving a decision on his exile from the Emperor. When Hilary arrived in exile, he wrote a second work, Adversus Arianos. Following the synod of Sirmium in 357 and his collaboration with Basil of Ancyra in early 358, Hilary recast his efforts and began to write De Trinitate. He decided to incorporate his two earlier works, De Fide and Adversus Arianos, into this project. Toward that end, he returned to his earlier works and drastically revised their content by adding new prefaces and new theological and exegetical material to reflect his mature pro-Nicene theology. These revisions and textual alterations have never before been acknowledged in the scholarship on De Trinitate.
