Hilary of Poitiers (c300-368), Bishop and Theologian, was instrumental in shaping the development of pro-Nicene theology in the West. Carl Beckwith engages the extensive scholarship on the fourth-century Trinitarian debates and brings new light on the structure and chronology of Hilary's monumental
