Cappadocian Fathers

Overview

The Cappadocian Fathers are Basil of Caesarea (known as Basil the Great, d. 379), his younger brother Gregory of Nyssa, bishop of Nyssa from 372, and Gregory of Nazianzus, called “the Theologian.” Historians of doctrine group the three as “the three Cappadocian bishops” who argued the Holy Spirit was not a created being but had existed eternally alongside the Father and the Son, sharing full deity with them.1 Together with Basil and Gregory of Nyssa’s answer to the subordinationist theologian Eunomius, that argument supplied terms the wider church adopted at the Council of Constantinople in 381.2 Scholarship warns, though, against treating the three as a single, uniform voice.3

Historical Context

Basil held the bishopric of Caesarea in Cappadocia; his own writings can be dated from their content, including Against Eunomius (364) and On the Holy Spirit (around 376).4 He appointed his younger brother Gregory of Nyssa bishop of the nearby see of Nyssa in 372.5 Gregory of Nazianzus, meanwhile, presided as bishop of Constantinople during the council held there in 381 and addressed the assembled bishops directly: his Oration 42, “Final Farewell,” was “originally delivered in Constantinople in 381 before the bishops attending the council and before Nazianzen’s own flock.”6

Modern scholarship’s habit of treating the three together is, on one telling, a convenience rather than a historical given. John McGuckin warns “against the contemporary overstatement that their theology was united and the same,” and Keith Goad notes “there is much evidence to show that the Cappadocians did not agree always fully with one another.”3 The clearest case is the Constantinopolitan creed itself: Gregory of Nazianzus argued more directly for calling the Spirit homoousios with the Father and the Son, but “Nazianzen’s articulation of the Spirit’s deity (with the confession of homoousios) was rejected in favor of Basil’s,” whose wording was more cautious.7 Assessments of Gregory of Nazianzus’s own place among the three have varied sharply: G. L. Prestige called him a mere “dignified popularizer” of Basil’s theology, while R. P. C. Hanson judged his articulation of Trinitarian doctrine “clearer, rather more forceful and expressive” than that of his two colleagues.3

Theological Contribution

Answering Eunomius

Eunomius of Cyzicus held that only the Father could be simple, reasoning that if the Son shared the Father’s being, divine simplicity itself would be compromised, and so called the Son heteroousios, “of a being that is other than or different from the Father.”2 Basil and Gregory of Nyssa “did more than anyone else to address this problem,” and “the solution they offered became the basis for the triumph of the Nicene ὁμοούσιον” at Constantinople in 381.2

The ousia/hypostasis grammar

Part of that solution was a settled distinction between ousia (“essence” or “substance”) and hypostasis (“person”), worked out in a letter traditionally numbered among Basil’s correspondence (Letter 38) but now generally attributed by patristic scholarship to Gregory of Nyssa; Basil makes the same distinction independently in his own uncontested letters.5 The tidy formula later generations used to summarize that grammar, “one ousia, three hypostases,” is a modern convenience rather than a phrase the Cappadocians themselves coined: Joseph Leinhard’s study finds it “is not found in Cappadocians’ writing precisely” and traces its first appearance instead to Augustine’s On the Trinity 5.8.10.8

Historical Significance

The Council of Constantinople in 381 condemned Eunomius and accepted “the doctrine of the ὁμοούσιον of the Father, Son, and Spirit,” building on the vocabulary Basil and Gregory of Nyssa had developed against him.9 The ousia/hypostasis distinction associated with Basil’s letters became one of the grammars later Trinitarian theology continued to draw on for stating how three persons share one divine essence.10
