Seven Fathers, thirteen centuries apart. Their major works, a famous quotation, and the doctrines each one spent his life defending.
The third Bishop of Antioch, and by tradition a disciple of the Apostle John. Arrested and taken to Rome for execution, he wrote seven letters along the route that remain the earliest substantial Christian writing outside the New Testament. He was thrown to wild beasts in the Roman Colosseum.
Epistle to the Ephesians. Epistle to the Magnesians. Epistle to the Trallians. Epistle to the Romans. Epistle to the Philadelphians. Epistle to the Smyrnaeans. Epistle to Polycarp.
"I am God's wheat, ground fine by the lions' teeth to be made pure bread for Christ."
The full, physical humanity of Christ, against docetism. The bishop as the center of unity in each local church. The reality of Christ's presence in the Eucharist.
Attended the Council of Nicaea in 325 as a young deacon, then spent most of his life as bishop defending its conclusions. Exiled five times by four different emperors for refusing to compromise on the full divinity of Christ. Known to history as the Father of Orthodoxy.
On the Incarnation. Orations Against the Arians. Life of Antony. His annual Festal Letters, one of which lists the 27 books of the New Testament as we now have it.
"God became man so that man might become god."
The Son as fully and eternally God, of one essence with the Father (homoousios). Rejection of Arianism, which held Christ was a created being.
Organized communal monasticism across the Eastern Church and wrote the monastic rule still influential in Orthodox monasteries today. Brother of St. Gregory of Nyssa and close friend of St. Gregory Nazianzen, together known as the Cappadocian Fathers. Built a large complex of hospitals and shelters for the poor outside Caesarea.
On the Holy Spirit. The Hexaemeron, homilies on the six days of creation. The Long Rules and Short Rules for monastic life. Numerous surviving letters and homilies.
"The bread you do not use is the bread of the hungry."
The full divinity of the Holy Spirit, against those who denied it. The distinction between essence (ousia) and person (hypostasis) that later grounded Trinitarian language.
One of only three men in Church history given the title "the Theologian," alongside St. John the Evangelist and St. Symeon the New Theologian. His Five Theological Orations, delivered in a small chapel in Constantinople, gave the Church its classical defense of the Trinity, and shaped the outcome of the Second Ecumenical Council.
The Five Theological Orations. Autobiographical poems, including De Vita Sua. A large collection of letters and orations.
"What has not been assumed has not been healed."
The full deity of the Holy Spirit as a third divine person. Precise Trinitarian language: three persons (hypostases), one essence (ousia). The full humanity of Christ, including a human mind and will, against Apollinarianism.
Called Chrysostom, "golden-mouthed," for his preaching. Hundreds of his homilies survive, including extensive verse by verse commentary on Matthew, John, and most of Paul's letters. Exiled twice for confronting corruption in the imperial court and clergy, he died from the harsh conditions of his final exile.
Homilies on Matthew. Homilies on the Gospel of John. Homilies on Romans and the Pauline epistles. On the Priesthood. The Divine Liturgy that still bears his name in Orthodox worship today.
"The rich exist for the sake of the poor. The poor exist for the salvation of the rich."
Scripture's plain, moral, and pastoral meaning, over speculative allegory. Almsgiving and care for the poor as inseparable from genuine Christian faith.
Defended the teaching that Christ has two complete wills, human and divine, against the imperially backed doctrine of Monothelitism. For refusing to recant, his tongue and right hand were cut off, and he died in exile shortly after. His writing on divine foreknowledge and human freedom is referenced elsewhere on this site.
The Ambigua. Questions to Thalassius. Chapters on Love. The Mystagogy.
"He who loves God cannot help but love every man as himself."
Christ possesses two complete, unconfused wills, against Monothelitism. Theosis as real, active cooperation (synergy) between divine grace and human freedom.
A monk of Mount Athos who defended hesychast prayer, the contemplative practice of stillness aimed at direct experience of God, against philosophical critics who called it incoherent. His answer became the essence and energies distinction still central to Orthodox theology, covered in full on this site's Articles page.
The Triads, in Defense of the Holy Hesychasts. The One Hundred and Fifty Chapters. Numerous homilies delivered as Archbishop of Thessalonica.
"God is entirely present in each of the divine energies."
The distinction between God's unknowable essence and his knowable, uncreated energies. The possibility of real, direct experience of divine light in this life.
Several articles draw directly on these Fathers, particularly the pieces on the Trinity and on essence and energies.
