Basil of Caesarea

← Encyclopedia

Basil of Caesarea, known in the Eastern churches as Basil the Great, was a fourth-century bishop, theologian, and ascetic whose work did much to settle the vocabulary in which the doctrine of the Trinity would afterward be stated. Born around 330 into a wealthy and devout Christian family of Cappadocia, in what is now central Turkey, he was educated in rhetoric and philosophy at Caesarea, Constantinople, and finally Athens, where he studied alongside his lifelong friend Gregory of Nazianzus. He, Gregory, and his younger brother Gregory of Nyssa are remembered together as the Cappadocian Fathers — the trio whose collective achievement, the Trinitarian grammar and the path of contemplative ascent, is treated under that heading; what follows is the man himself.

A Cappadocian house

The family was a small dynasty of sanctity, and Basil never forgot that he was its product. His grandmother, Macrina the Elder, had kept the faith through the persecution under the emperor Galerius, hiding in the forests of Pontus; from her, by his own account, he had the first form of the Christian doctrine he would later defend with the apparatus of the schools. His father, Basil the Elder, was a rhetor of Neocaesarea; his mother, Emmelia, bore ten children, of whom an unusual number entered the church’s history. His elder sister Macrina the Younger turned the family estate at Annesi, on the river Iris, into an ascetic community and ruled it as its mistress; she appears in Gregory of Nyssa’s writing as a philosopher who could instruct her brothers on the soul. Two more brothers became bishops — Gregory of Nyssa, the most daring mind of the three Cappadocians, and Peter of Sebaste. A fourth, the promising Naucratius, died young in a hunting accident, a loss that pressed the household further toward renunciation.

Into this world Basil brought the best secular education the empire could furnish. After Caesarea and a period at Constantinople he went up to Athens around 350 and stayed some five years, reading rhetoric and philosophy in the city that was still the prestige center of Greek learning. There he formed the friendship with Gregory of Nazianzus that would shape both their lives, and there, the sources say, he sat in the same lecture halls as the young man who would become the emperor Julian and try to turn the empire back to the old gods. Basil came home a polished rhetorician with, for a time, every prospect of a public career. What turned him was partly his sister: Macrina, Gregory of Nyssa reports, rebuked him for the vanity his learning had bred. He was baptized around 357, gave up the prospect of the schools, and after touring the monks of Egypt, Syria, Palestine, and Mesopotamia withdrew to Annesi to live the ascetic life he had seen practiced there.

The grammar of the Trinity

The decisive controversy of his life concerned how the unity and the threeness of God were to be spoken of at once. The dispute, generally called Arian after the Alexandrian presbyter Arius, turned on whether the Son was fully and eternally divine or a subordinate creature made by the Father. The Council of Nicaea in 325 had answered with a word — homoousios, of one substance — but a word is not yet a grammar, and for two generations the Greek-speaking churches argued over what the word could bear. The terms ousia (substance, essence) and hypostasis (subsistence, concrete existence) had long run together almost as synonyms; depending on how one read them, the consubstantial formula could be heard as collapsing the three into one being with no real distinctions, or as splitting the Godhead into three separate beings — three gods.

Basil’s contribution was as much linguistic as doctrinal. He and the Cappadocians pressed a clean distinction between the two words and held it in place: one ousia, the single undivided divine essence, subsisting in three hypostases, the distinct real modes in which each of the three is that one essence — one substance in three subsistences. What distinguishes the persons is not the essence, which is common, but the relations of origin: the Father unbegotten, the Son begotten, the Spirit proceeding. The formula gave the Nicene position a precision it had lacked, a structure exact enough to hold an argument open for fifty years and then close it. It stands behind the creed reaffirmed at the Council of Constantinople in 381 — two years after Basil’s death — which expanded the Nicene confession and strengthened its clause on the Holy Spirit. Basil did not live to see the council ratify the work of his life.

He had, however, written the book that the council’s pneumatology needed. His treatise On the Holy Spirit, composed around 375 for his disciple Amphilochius of Iconium, addressed those who would leave the Spirit’s status undefined, granting it honor without quite calling it God. Basil argued from the practice of worship itself: the Spirit is named with the Father and the Son in baptism and in the doxology, and what the church worships together cannot be ranked into creature and creator. He moved with characteristic caution — he did not, in that work, flatly call the Spirit homoousios, preferring to establish that the Spirit is to be glorified together with the Father and the Son and to let the conclusion follow. The restraint was tactical, the work of a bishop counting his allies in a divided church; the substance pointed where the council would go. Earlier, in his three books Against Eunomius, he had already taken on the most rigorous of the anti-Nicene thinkers, Eunomius of Cyzicus, who claimed the divine essence could be seized in a single name. Against that confidence Basil set the principle that the names of God record our approach to him and do not capture what he is — the seed of the negative theology that his brother Gregory would grow into a whole spirituality, and which belongs to the Cappadocian story as a whole.

The bishop and his city

In 370 Basil was consecrated bishop, or metropolitan, of Caesarea, the chief city of Cappadocia and a see that carried authority over the surrounding province. He had been ordained priest some years before and had already done much of the real labor of the diocese; the elevation made official a leadership that was already his. It set him at once against the court. The emperor Valens, who ruled the East, was committed to a homoian, broadly Arian settlement and moved to bring the recalcitrant bishops into line. The confrontation that the tradition remembers came when Valens sent his praetorian prefect, Modestus, to Caesarea to break Basil’s resistance with threats of confiscation, exile, and death. Basil, the story runs, met each threat by pointing out that a man who owned nothing could not be impoverished, that exile only sent him sooner to the God he served, and that death would be a kindness. Modestus reported that he had never been spoken to so; Basil answered that the prefect had perhaps never before met a bishop. The exchange may be polished in the retelling, but the outcome is historical: Valens left Caesarea and its bishop alone.

Valens also tried to weaken Basil by administrative means, dividing Cappadocia into two provinces and so halving the reach of his metropolitan see. Basil answered by multiplying bishoprics in the contested territory and filling them with his own men — a maneuver that strained even his closest friendships. He consecrated Gregory of Nazianzus to the miserable post of Sasima, a dusty staging town on the new border, and pressed his brother Gregory into the see of Nyssa. Nazianzus never forgave the appointment and never took up the post; the episode shows the harder, more political Basil that the hagiography tends to soften — a man who would spend a friendship to hold a frontier.

The most enduring of his works as bishop was not a treatise but a building. On the outskirts of Caesarea, around 372, Basil raised a complex of charitable institutions so large that Gregory of Nazianzus, in the funeral oration he delivered for his friend, called it a new city, a treasury of piety. The Basileias — the name later attached to it from Basil’s own — gathered a hospice for travelers, a poorhouse, and, at its heart, a hospital with resident physicians and nurses, together with a separate house for the care of lepers, whom Basil is said to have embraced in person when others would not touch them. The famine that struck Cappadocia in 369, before his episcopate, had already moved him to sell off inherited property and organize relief; the Basileias institutionalized that response. It stands among the earliest organized hospitals in the Western and Eastern record — a permanent establishment where the sick poor were lodged, fed, and treated as a matter of settled policy rather than occasional alms. The conviction behind it was of a piece with his theology: the God who cannot be reached by any name is nonetheless met, concretely, in the served body of the neighbor.

Rule and community

Alongside the dogmatic and the civic work ran a third, the monastic. Basil drew up guidance for communal ascetic life that survives chiefly in two collections, conventionally called the Longer Rules and the Shorter Rules, together making up his Asketikon — not a single legislated code on the later Western model but a body of questions and answers worked out, revised, and circulated over years. Their cast is decisive for the shape of Eastern monasticism: against the prestige of the solitary hermit, Basil argued for life in common. The solitary, he reasoned, has no one to serve and so cannot fulfill the command of love; he has no one to correct his faults and no occasion to practice the humility, obedience, and patience that the common life forces on a person at every hour. The monastery is therefore not a refuge from the world’s demands but a school of them, ordered around shared prayer, manual labor, the reading of scripture, and care for the poor — the same care his hospital made civic. He kept the houses moderate, set within reach of the church rather than fled to the deep desert, and bound to works of mercy rather than feats of solitary endurance.

This communal, scripturally governed, charity-directed model became the foundation of Orthodox monastic life and the standard against which it has measured itself ever since. Its reach did not stop at the Greek world. When Benedict of Nursia composed his rule for the Latin West in the sixth century, he named Basil explicitly, commending the rule of the holy father Basil to the monks who wanted to go further than his own modest provisions; a Latin version of the Asketikon, made by Rufinus of Aquileia around 397, had carried Basil’s prescriptions west well before. The two great rules that organized monastic Christianity, East and West, thus run back through a single Cappadocian hand — the communal life as Basil framed it, inherited whole in the Greek churches and threaded into the Benedictine settlement that would govern the Latin ones.

The bee and the flower

Basil’s relation to the pagan philosophical culture he was trained in was deliberate rather than hostile, and he set it out in a short address to young men on how they might draw profit from Greek literature — a text written, on the usual dating, for the young of his own family and circle. He did not pretend the classics were harmless, and he did not pretend they were dispensable. His image for the right use of them is the one the work is remembered by: the Christian reader should treat the writings of the Greeks as bees treat a meadow, not settling on every flower nor carrying off whole the ones they visit, but taking only what nourishes and leaving the rest behind. Poetry that praised virtue and condemned vice was to be welcomed as a preparation for scripture, a training of the soul’s eye before it could bear the brighter light; what was base or false was to be passed over as the bee passes the flower that yields no honey. Plato supplied much of the moral psychology that made the case workable, and the address reads in places as an exercise in Platonism turned to a Christian end.

The borrowing went deeper than this one programmatic text. Scholars have traced the mark of Platonic and Stoic thought through his homilies, above all the Hexaemeron, the nine sermons on the six days of creation that he preached, probably late, to a working congregation of Caesarea. There Basil walked through the Genesis account day by day, and to fill it out he reached for the natural philosophy of the schools — the four elements and their qualities, the generation and corruption of bodies, the order of the heavens — drawing on Stoicism for its physics of an organized, providentially governed cosmos and on the Platonic tradition for the structure of a world that images an intelligible order. He used the learning and at the same time kept it in its place, refusing the philosophers’ eternal world in favor of a creation called out of nothing in time, and breaking off, more than once, to remind his audience that he was expounding scripture and not delivering a lecture on astronomy. The philosophy was equipment, taken up where it served the text and dropped where it did not — the bee’s discrimination applied to cosmology.

This measured engagement places Basil within a long line of Christian thinkers who tried to make the inheritance of the Logos at home in the faith without surrendering to it. Justin Martyr had claimed the truths of the philosophers as seeds of the same Word made flesh; Clement of Alexandria had treated Greek philosophy as a tutor that led the Greeks toward Christ as the law led the Jews; Origen, the towering Alexandrian whom Basil and Gregory of Nazianzus had honored by compiling an anthology of his writings, the Philokalia, had built the most ambitious synthesis of biblical exegesis and Platonic metaphysics the early church produced. Behind all of them stood the Jewish exegete Philo of Alexandria, whose allegorical reading of the Hebrew scriptures had first shown how the Greek philosophical vocabulary might be made to serve a revealed text — and whose own hexaemeral commentary lay somewhere behind Basil’s. The Neoplatonism that was, in Basil’s own century, the living philosophy of the schools furnished categories his whole generation breathed. Basil’s distinction within this lineage is his restraint: where Origen had let the philosophy carry him to speculative conclusions the later church could not keep, Basil took the equipment and refused the overreach, a discipline that helped make the Greek inheritance safe for the church to own.

The texts and the scholarship

Basil’s surviving corpus is large and well attested: the dogmatic works Against Eunomius and On the Holy Spirit; the Hexaemeron and other homilies; the ascetic Asketikon; and a collection of more than three hundred letters that is among the richest bodies of fourth-century correspondence, ranging from theological argument to the daily administration of a diocese. The standard nineteenth-century English gateway to all of this remains the Nicene and Post-Nicene Fathers, Series II, Volume VIII — St. Basil: Letters and Select Works, translated by Blomfield Jackson and edited by Philip Schaff and Henry Wace in 1895 — which carries the De Spiritu Sancto, the nine homilies of the Hexaemeron, and the complete letters into English; the volume is in the public domain and freely read in full through the Christian Classics Ethereal Library. Within it the most consequential single page is Letter 234, written to Amphilochius, where Basil states the principle that became the charter of Eastern negative theology: the divine operations are many and the divine essence simple, and the church knows its God from his operations — his energeiai — while it does not undertake to approach near to his essence. That distinction between the unknowable essence and the participable energies would be raised, a thousand years later, into the central doctrine of late Byzantine Orthodox mysticism.

The address on Greek literature has its own textual afterlife. The standard early English version is Frederick Morgan Padelford’s, published in Essays on the Study and Use of Poetry by Plutarch and Basil the Great (Yale Studies in English, 1902) and now in the public domain; Padelford’s rendering of the bee-simile is the form in which the passage is most often quoted, and it is available in full at Wikisource. A facing-page Greek-and-English edition by Roy Joseph Deferrari and Martin McGuire later appeared in the Loeb Classical Library. The complete English translation of the three books Against Eunomius, long lacking, was supplied only in 2011 by Mark DelCogliano and Andrew Radde-Gallwitz in the Fathers of the Church series — a reminder that even a figure this central left works that the modern reader could not read whole until very recently. The standard modern life is Philip Rousseau’s Basil of Caesarea (1994), which reads the letters and treatises as the record of a churchman building authority under pressure; the doctrinal achievement is set in its longer arc by Jaroslav Pelikan in The Emergence of the Catholic Tradition (1971), the first volume of his history of the development of Christian doctrine. For the hospital, the indispensable primary witness is Gregory of Nazianzus’s funeral oration on Basil (Oration 43), the source of the new-city image, whose account is examined in modern reconstructions of the Basileias such as the medical-history study hosted by Hektoen International.

Basil died on the first of January, 379, worn out by chronic illness and the austerities he had practiced since his twenties, not yet fifty. He had fixed a grammar he would not see ratified and built a city of the sick he could not have foreseen would outlast the empire that hosted it. The two works were one work. The same conviction that drove him to insist, against Eunomius, that the living God lies beyond the reach of every human word drove him to lodge the poor and wash the lepers of Caesarea: a God who exceeds all naming is honored not by the perfecting of speech but by the deed done to the least body in the street. The precision of the council and the warmth of the poorhouse came from the same source — and in the Eastern churches, where he is reckoned among the greatest of the teachers and his liturgy is still served on the days that bear his name, it is the bishop who held the two together, the exact word and the open door, who is remembered as Basil the Great.
