Basil of Caesarea (ca. 330–378) spent most of his ecclesiastical career combating what he took to be the triple threat of the Heteroousian theology of Eunomius, the Pneumatomachian theology of Eustathius of Sebasteia, and the modalist theology of Marcellus of Ancyra, in the course of which he played a seminal role in the development of the doctrine of the Trinity declared orthodox at the Council of Constantinople in 381. He has generally not been recognized for his Christological contributions. While it is true that the controversy over Apollinarius emerged in the last few years of his life, he did not leave behind a specifically anti-Apollinarian work as did his fellow Cappadocians Gregory of Nazianzus and Gregory of Nyssa. Nonetheless, Basil’s Christology is important because it is a witness to the Christological concerns in the mid-fourth century before the controversy over Apollinarius came to dominate the Christological agenda in the East for the next generation or two. Unfortunately, his Christology has to be pieced together from various comments scattered throughout his corpus.
