Canonised Father of the Church

Basil the Great

Also known as Basil of Caesarea; Basil the Great

Bishop of Caesarea in Cappadocia, organiser of monastic life and of the Church's care for the poor, and the theologian whose work on the Holy Spirit made the Council of Constantinople possible.

  • Received Orthodox teachingTaught consistently and received throughout the Orthodox Church, though not necessarily formulated in a conciliar definition. This is not a claim that no Father ever wrote differently.
  • Dogmatic definitionDefined by an ecumenical council or otherwise confessed by the Church as binding doctrine. Not every sentence a council wrote is a definition: its acts, letters and disciplinary canons are different things.
  • Canonical normEstablished by a received canon of a council, or of a Father whose canons the Church has received. Canons are applied within the Church's pastoral and conciliar life; a canon is not a rule a reader applies to themselves or to anyone else.
  • Liturgical witnessAttested in the Church's worship — in a hymn, a prayer, a rite or a commemoration. Liturgical language is theological rather than casual, but a hymn is not a canon.
  • Historical consensusBroadly agreed among historians working from the surviving evidence. Consensus can shift when the evidence or the method changes.

Life

Basil came from a family of remarkable Christians — his grandmother, his mother, his sister Macrina and two of his brothers are all honoured as saints. He studied at Athens alongside Gregory of Nazianzus, spent time among the ascetics of Egypt and Syria, and returned to organise monastic life in Cappadocia.

As bishop of Caesarea from 370 he built what amounted to a new town outside the city — hospital, hostel, workshops, provision for lepers — funded from Church resources and known afterwards as the Basiliad. He also stood up to imperial pressure during the Arian sympathies of the emperor Valens.

He died at forty-nine, worn out, eighteen months before the Council of Constantinople confessed the divinity of the Spirit he had spent his life defending.

Works

Generally accepted as authentic

  • On the Holy Spirit
  • The Longer and Shorter Rules — Not archived here. The foundation of Orthodox monastic life.
  • The Hexaemeron — Homilies on the six days of creation. Not archived here.
  • The Letters, including the canonical letters to Amphilochius — Not archived here; the canonical letters are part of the received canonical corpus.
  • The Liturgy of Saint Basil — Celebrated ten times a year in the Byzantine rite. The relationship of the received text to Basil's own work is a scholarly question, not a settled attribution.

Theological and spiritual contribution

On the Holy Spirit argues for the Spirit's divinity in a way that avoids the word homoousios and reaches the same result: the Spirit is glorified with the Father and the Son, and what is offered worship is God. Basil's method is to argue from how the Church actually prays and baptises. It is one of the clearest instances in the Fathers of worship functioning as a theological source.

With his brother Gregory of Nyssa and his friend Gregory of Nazianzus, he gave the Church the settled Trinitarian formula: one ousia in three hypostasis. Fixing that distinction, which earlier usage had blurred, is what made the fourth-century arguments resolvable.

His monastic rules turned solitary asceticism into an ordered common life with obedience, work, prayer and hospitality, and his canonical letters became part of the Church's received canon law.

  • Gregory the Theologian

    One of only three figures the Orthodox Church calls the Theologian, whose five orations on the Trinity settled how the Church would speak of God, and who resigned the see of Constantinople rather than prolong a quarrel.

    Father or writer

  • Gregory of Nyssa

    Basil's younger brother, the most speculative of the Cappadocians, whose account of the soul's endless progress into God shaped Orthodox mystical theology.

    Father or writer

  • The First Council of Constantinople

    The council that confessed the divinity of the Holy Spirit and gave the Church the Creed it recites today. It was not ecumenical when it met; the Church made it so by receiving it.

    Council

  • The Holy Spirit

    The Spirit who proceeds from the Father, worshipped and glorified with the Father and the Son.

    Theme

  • The ascetic life

    Fasting, prayer and the healing of the passions — as therapy, not as achievement.

    Theme

  • The Holy Spirit and Pentecost

    How the Church came to confess the Spirit as God, and why Basil argued from the way the Church prays.
