Basil of Caesarea is considered one of the architects of the Pro-Nicene Trinitarian doctrine adopted at the Council of Constantinople in 381, which eastern and western Christians to this day profess as "orthodox." Nowhere is his Trinitarian theology more clearly expressed than in his first major doctrinal work, Against Eunomius, finished in 364 or 365 CE. Responding to Eunomius, whose Apology gave renewed impetus to a tradition of starkly subordinationist Trinitarian theology that would survive for decades, Basil's Against Eunomius reflects the intense controversy raging at that time among Christians across the Mediterranean world over who God is. In this treatise, Basil attempts to articulate a theology both of God's unitary essence and of the distinctive features that characterize the Father, Son, and Holy Spirit―a distinction that some hail as the cornerstone of "Cappadocian" theology. In Against Eunomius, we see the clash not simply of two dogmatic positions on the doctrine of the Trinity, but of two fundamentally opposed theological methods. Basil's treatise is as much about how theology ought to be done and what human beings can and cannot know about God as it is about the exposition of Trinitarian doctrine. Thus Against Eunomius marks a turning point in the Trinitarian debates of the fourth century, for the first time addressing the methodological and epistemological differences that gave rise to theological differences. Amidst the polemical vitriol of Against Eunomius is a call to epistemological humility on the part of the theologian, a call to recognize the limitations of even the best theology. While Basil refined his theology through the course of his career, Against Eunomius remains a testament to his early theological development and a privileged window into the Trinitarian controversies of the mid-fourth century.

Author
Basil of Caesarea (Arabic: باسيليوس الكبير; Greek: Ἅγιος Βασίλειος ὁ Μέγας), also called Saint Basil the Great, was the bishop of Caesarea Mazaca in Cappadocia, Asia Minor (modern-day Turkey). He was an influential 4th century Christian theologian and monastic. Theologically, Basil was a supporter of the Nicene faction of the church, in opposition to Arianism on one side and the followers of Apollinaris of Laodicea on the other. His ability to balance his theological convictions with his political connections made Basil a powerful advocate for the Nicene position. In addition to his work as a theologian, Basil was known for his care of the poor and underprivileged. Basil established guidelines for monastic life which focus on community life, liturgical prayer, and manual labor. Together with Pachomius he is remembered as a father of communal monasticism in Eastern Christianity. He is considered a saint by the traditions of both Eastern and Western Christianity. Basil, Gregory of Nazianzus, and Gregory of Nyssa are collectively referred to as the Cappadocian Fathers. The Eastern Orthodox Church and Eastern Catholic Churches have given him, together with Gregory of Nazianzus and John Chrysostom, the title of Great Hierarch. He is recognized as a Doctor of the Church in the Roman Catholic Church. He is sometimes referred to by the epithet Ouranophantor (Greek: Οὐρανοφάντωρ), "revealer of heavenly mysteries".
