The First Council of Nicaea — Vasily Surikov (1876), public domain

The Great Cloud of Witnesses · Era 3 of 10

The Fathers & the Creeds

AD 313–600

The persecution stopped and the arguments started. In these three centuries the church put into careful words who Jesus is — and recognized which books were Scripture.

Thou madest us for Thyself, and our heart is restless, until it repose in Thee.

Augustine of HippoConfessions, Book I, chapter 1 (written c. AD 397–400; E. B. Pusey translation, public domain)
Who
Constantine, Arius, Athanasius, the Cappadocian Fathers, Jerome, Ambrose, John Chrysostom, and Augustine of Hippo.
What
The great councils — Nicaea (325), Constantinople (381), Chalcedon (451) — hammered out the creeds, while the church settled its list of New Testament books.
Where
Around the Mediterranean: Nicaea and Constantinople in the east, Alexandria in Egypt, Milan and Rome in Italy, Hippo in North Africa.
Why it matters
The words you say in the Nicene Creed and the twenty-seven books in your New Testament both come from here. This is where the church defended the deity of Christ.

The dated line

  1. 313The Edict of Milan makes Christianity legalConstantine and Licinius agreed that everyone in the empire could worship as they chose, and ordered confiscated church property returned. After nearly three centuries of being an illegal religion, the church woke up protected.
  2. 325The Council of NicaeaAbout three hundred bishops met in a lakeside town in what is now Turkey to answer Arius, an Alexandrian pastor who taught that the Son was God's first and greatest creature — glorious, but made, so that "there was when He was not." The council answered with one word: the Son is homoousios with the Father, of the very same being — begotten, not made.
  3. 335Athanasius is exiled for the first timeThe bishop of Alexandria, who had been at Nicaea as a young deacon, was banished to Trier in Germany after a rigged synod. Four more exiles followed; he spent roughly seventeen of his forty-five years as bishop away from his city.
  4. 367Athanasius's Easter letter lists the twenty-sevenHis thirty-ninth Festal Letter names exactly the twenty-seven books of the New Testament we use today — the earliest surviving list that matches ours. Councils at Hippo (393) and Carthage (397) confirmed the same list in the West.
  5. 380Nicene Christianity becomes the empire's official religionThe Edict of Thessalonica, issued by Theodosius I, commanded all his subjects to hold the faith of Nicaea. Legal protection had become legal privilege — and pressure on everyone else.
  6. 381The Council of ConstantinopleAround a hundred and fifty bishops confirmed Nicaea and expanded its article on the Holy Spirit, who "proceeds from the Father" and "together with the Father and the Son is worshiped and glorified." This 381 text is the creed most churches actually recite as the Nicene Creed.
  7. 386Augustine converts in a Milan gardenA thirty-one-year-old professor of rhetoric, weeping under a fig tree, heard a child's voice chanting "take up and read," opened Paul's letter to the Romans, and stopped running. His mother Monica had prayed for him for years; Bishop Ambrose's preaching had already broken his objections.
  8. c. 397–400Augustine writes the ConfessionsHe told his whole story — theft, ambition, a long affair, a slow surrender — as one long prayer addressed to God. Nothing quite like it had been written before, and it invented the spiritual autobiography.
  9. c. 405Jerome finishes translating the Old Testament from HebrewCommissioned by Bishop Damasus in 382, Jerome worked for decades in Bethlehem, learning Hebrew so he could go behind the Greek to the original. His Latin Bible, later called the Vulgate, was the Bible of the West for a thousand years.
  10. 410Rome is sacked; Augustine begins The City of GodAlaric's Goths took the eternal city, and pagans blamed the Christians for abandoning the old gods. Augustine answered across thirteen years (413–426) with a book about two cities — one built on love of self, one on love of God — and only one of them permanent.
  11. 431The Council of EphesusBishop Nestorius objected to calling Mary Theotokos, "God-bearer," and Cyril of Alexandria pressed the point that the title is a claim about the child, not the mother: the one she bore was God. The council agreed, though the politics around it were ugly.
  12. 451The Council of ChalcedonSome five hundred bishops set the boundary lines that have held ever since: Jesus is one person in two natures, truly God and truly man, "without confusion, without change, without division, without separation." It fenced the mystery rather than explaining it.
  13. c. 529Benedict settles at Monte CassinoOn a hilltop between Rome and Naples he founded the monastery where he wrote his Rule — a short, humane handbook of prayer, work, study, and stability. It became the pattern for Western monasticism.
  14. 590Gregory the Great becomes bishop of RomeA monk who did not want the job took charge of a city ruined by plague, famine, and war, fed the poor from church estates, wrote a manual on pastoral care, and in 596 sent missionaries to England. The ancient world was gone; he organized what came next.

The story

01From hunted to official — and what that cost

The change came fast enough to give the church whiplash. Diocletian's persecution ended in 311; the Edict of Milan legalized the faith in 313; within a lifetime Christianity was the empire's official religion. Bishops who still carried scars from the mines were suddenly riding in imperial carriages. Men who had been hunted were now consulted.

Be honest about what that cost. The church gained peace, buildings, schools, the freedom to think out loud, and the leisure to do serious theology — Nicaea would have been unimaginable in a prison. But it lost some of its edge. Becoming a Christian stopped costing anything and started helping a career, and crowds came in who had not counted any cost at all.

It also began an entanglement the church has never fully undone. In 380 Theodosius commanded his subjects to hold the Nicene faith. In 385 a Spanish teacher named Priscillian was executed at Trier for heresy — the first such execution by a Christian state — and to their credit Ambrose of Milan and Martin of Tours protested it loudly. The sword that had struck the church was now available to the church, and that is a dangerous thing to hold.

02The fight over who Jesus is: Arius, Athanasius, the Cappadocians

The great fight of the era was not politics dressed up as theology. Arius taught that the Son was the highest and first of all creatures — magnificent, before all worlds, but made — and if he was right, the church at prayer had been worshiping a creature. Athanasius would not let it go, for one reason: only God can save, so if Jesus saves, then Jesus is God. At Nicaea in 325 the bishops reached for a word that is not in the Bible in order to protect what the Bible says — homoousios, of the same being: whatever the Father is, the Son is. Arius's supporters could sign almost anything else; they could not sign that.

Nicaea did not end it. For half a century the emperors leaned back toward Arius, and Athanasius, bishop of Alexandria from 328, was driven out five separate times — banished to Germany, hiding in the desert with monks, once hunted by soldiers up the Nile. The phrase that stuck to him is Athanasius contra mundum, Athanasius against the world. He outlived his opponents and died in his own city in 373, and the truth he defended outlived them all.

The finishing work belonged to three friends from Cappadocia in central Turkey: Basil the Great, his brother Gregory of Nyssa, and Gregory of Nazianzus. They gave the church language careful enough to say what it meant — one being, three persons — and they pressed the argument through to the Holy Spirit, who is worshiped, not used. The Council of Constantinople in 381 wrote their work into the creed, and that is the version most congregations still recite.

03How the New Testament list was settled

The New Testament settled in these same years, and it settled by recognition rather than by decree. Churches from Gaul to Syria had been reading the same books for generations; what the fourth century did was write the list down. Athanasius's Easter letter of 367 names our exact twenty-seven, and the councils at Hippo and Carthage confirmed it in the 390s. No council handed the church a Bible it did not already have.

04Augustine, and the two books the church never put down

Then there is Augustine, the era's giant. A gifted, restless North African who chased philosophy, ambition, and pleasure across the Mediterranean while his mother Monica prayed and followed; who lived with a woman for years and fathered a son; who sat in Ambrose's congregation in Milan arguing with the sermon and losing. He broke in a garden in 386 at the sound of a child's voice telling him to take up and read.

He gave the church two books it has never put down. The Confessions told his own story as a prayer, and it still reads like someone speaking in the next room. The City of God, written while the empire came apart, argued that history runs on two loves building two cities, and only one of them is permanent. He died in 430 with Vandal armies at the walls of his own town of Hippo.

05The desert, and the last hard sentence at Chalcedon

Meanwhile another movement was going the other direction. When faith turned respectable, thousands walked out into the Egyptian desert to keep it costly — Antony alone in the wilderness, Pachomius organizing the first communities, Basil writing rules for the East, Benedict at Monte Cassino writing the rule that shaped the West. Monasticism began as a protest against a comfortable church, and by accident it became the West's memory: monks copied the books that would otherwise have burned.

Chalcedon in 451 said the last hard thing in plain words: Jesus is one person, not two, fully God and fully man, and neither nature swallows the other. He is not God wearing a man's costume, and He is not a good man with God poured in. Honesty requires adding that the churches of Egypt, Syria, and Armenia read the wording differently and did not accept it — the first lasting split in Christendom, and one that modern dialogue suggests was more about language than about Christ. East and West were drifting apart as well, as Greek and Latin scholars stopped reading each other. Western councils even began adding "and the Son" to the creed's line about the Spirit, starting locally at Toledo in 589 — a change the East never agreed to and never forgot.

06Honor them as witnesses, and no more than that

Honor these men as witnesses without making them more than that. They fought for the deity of Christ, the reliability of Scripture, and the gospel of grace, and every believer since has lived off their work. But the church of AD 400 is not the church of AD 1400; the papal claims, the practices, and the accumulated tradition of later centuries should not be read backward onto Athanasius or Augustine. They pointed to Scripture and Christ. That is where they wanted us looking.

The statement that Jesus is one person in two complete natures, divine and human, neither blended together nor pulled apart.

The Apostles' Creeddeveloped over centuries; final wording c. 700s

A baptismal confession that grew out of the older Roman creed of the second and third centuries; the story that the twelve apostles each wrote a line is a later legend, but the content is ancient.

The Rule of Benedictc. 530

A brief, surprisingly gentle rule for community life — hours for prayer, hours for work, hours for reading — that shaped Europe's monasteries for centuries.

What this era handed the church

  • The Nicene Creed is still the closest thing the worldwide church has to a common confession — Protestant, Catholic, and Orthodox recite the same words.
  • The twenty-seven-book New Testament on your shelf is the list recognized and written down in these centuries.
  • Chalcedon's fence still marks the boundary of orthodox teaching about Christ: fully God, fully man, one person.
  • Augustine's thinking on grace, sin, and the human heart runs straight through the Reformation — Luther was an Augustinian monk, and Calvin quoted him more than any other father.
  • Monasteries founded in this era preserved the Scriptures and the classics through the collapse of the Roman West.
  • The era also handed down a warning: a church protected by the state becomes a church tempted to use the state, and that account came due for centuries afterward.
