Lecture 12: Easter, Athanasius Against the World, and the Cappadocian Fathers

The lecture, section by section

1. Seven councils, and what ecumenical means

   Ecumenical here means worldwide, not compromising: councils where the whole church, east and west, was present. Church history counts seven major ecumenical councils, Jerusalem in Acts standing apart as the apostolic original. Nicaea in 325 was the first, made possible only because Constantine's peace let the bishops finally gather, and called by an emperor whose interest was political unity, not doctrine.

2. Why Easter moves

   Nicaea's second dispute was the date of the resurrection celebration: the West kept it on a Sunday, while some in Asia Minor kept the Passover timing, since Christ is the true Passover lamb. The council fixed it to the first Sunday after the first full moon after the spring equinox, deliberately severing it from Passover, a choice driven partly by the church's growing determination to distance itself from anything Jewish. That formula is why Easter wanders across the calendar to this day; the pagan name Easter attached much later, when Germanic tribes brought the word to a thoroughly biblical event. Busenitz's verdict: the council got the deity of Christ exactly right and the calendar permanently complicated.

3. How replacement theology grew

   A student's question opens a preview: the church-replaces-Israel idea entered with the Epistle of Barnabas and hardened over four centuries until Augustine, who kept the Jews in his system only as an apologetic witness that the Old Testament happened, with no future in God's promises. The early church was premillennial with Israel pushed out; the Puritans, curiously, reversed it, denying the millennium while expecting a future mass conversion of the Jews. Busenitz notes that Augustine himself began a premillennialist and switched, and his switch set the medieval default, a story the course will return to.

4. The creed that grew, and the clause that split

   The Nicene Creed of 325 said simply, and in the Holy Spirit; the council of Constantinople in 381 expanded that clause into a full confession of the Spirit's deity, producing the Niceno-Constantinopolitan Creed everyone still calls the Nicene Creed. One later western addition, that the Spirit proceeds from the Father and the Son, filioque in Latin, the East never accepted, and that clause would one day help split Christendom in two.

5. The great fourth century

   The Nicene and post-Nicene age, 325 to the fall of Rome in 476, may be the third most important century stretch in church history after the apostolic first and the Reformation sixteenth. Freed from persecution, the church produced a constellation of giants at once: Athanasius, Ambrose of Milan, John Chrysostom, Jerome the translator, Augustine, and in Asia Minor the Cappadocians, Basil the Great, his brother Gregory of Nyssa, and their friend Gregory of Nazianzus.

6. Athanasius contra mundum

   A young deacon at Nicaea, bishop of Alexandria at thirty three, Athanasius spent forty five years defending the creed through five separate exiles as emperors and court factions swung Arian and back; when Julian the Apostate reigned, he fled to the Egyptian desert for his life. Tradition gives him the phrase Athanasius against the world, and though, like Elijah, he was never truly alone, God providentially used his stubbornness, Piper calls him the saint of stubbornness, to preserve the truth. His On the Incarnation of the Word of God states what was at stake: the mediator between God and men must be fully God and fully man, or there is no salvation. He died in 373, eight years short of the final victory.

7. Whose counterfactual?

   Busenitz gently corrects the suggestion that had Athanasius failed, church history would simply have gone Arian. God's purposes do not hang on one man's nerve; had Athanasius fallen, God's sovereign plan would have run through other means. The right frame honors the instrument without making providence depend on it.

8. The councils were not the authority, even then

   The Roman and Eastern churches came to treat the councils as near-inspired, but the fourth century itself tells another story: for fifty six years after Nicaea the empire largely ignored the council's ruling, and when Constantinople reaffirmed it in 381, the ground of the reaffirmation was that the doctrine is biblical, not that Nicaea had spoken. Our confidence in Christ's deity rests where theirs did: on Scripture, with the councils as witnesses, and their vocabulary as a gift.

9. The death of Arius

   Busenitz reads Athanasius's own letter recounting it. Arius, restored to favor by powerful friends, swore before Constantine that he held the orthodox faith, and the emperor answered: if you have sworn falsely, may God judge you according to your oath. When his allies vowed to force him into communion the next day, bishop Alexander of Constantinople lay prostrate in the church and prayed that God would either take his own life or remove Arius rather than let heresy sit at the table. That Saturday Arius, in Scripture's words about Judas, fell headlong and burst open, and died. Athanasius insists the church rejoiced not at a death but at a judgment; Busenitz offers it as history's punctuation mark, not a pattern for prayer. Arius died in 336; his movement outlived him to 381.

10. The Athanasian Creed

    A later summary of Athanasian doctrine, in the lecture's view likely penned by Ambrose though no one knows, the Athanasian Creed gives the Trinity its most exact short form: we worship one God in Trinity and Trinity in unity, neither confounding the persons nor dividing the substance, the glory equal, the majesty co-eternal. And it binds the incarnation to salvation itself: the right faith is that our Lord Jesus Christ, the Son of God, is God and man.

11. The Cappadocians and the Spirit

    Basil the Great, Gregory of Nyssa, and Gregory of Nazianzus pastored in Asia Minor, the very stronghold of Arianism, and carried Athanasius's fight to its 381 victory, adding a deliberate emphasis the Nicene moment had not needed: the full deity and personhood of the Holy Spirit. Basil argues it verse by verse, the Spirit good by nature as the Father and Son are, knowing the deep things of God (the words of 1 Corinthians 2), giving life as only God gives it, and asks who could be so unfed by God's words as to rank the Spirit with the creatures.

12. Let Scripture be our umpire

    Accused by the Arians of tritheism, and then, when they denied it, of Sabellianism, Gregory of Nyssa faced the deadlock of rival traditions and named the only exit: we do not make custom the rule of sound doctrine; let the inspired Scripture be our umpire, and the vote of truth will go to those whose dogmas agree with the divine words. Written decades after Nicaea, it appeals not to the council but to the Bible: sola Scriptura in the fourth century. Busenitz closes on tradition itself: apostolic tradition is real and Protestants gladly hold it, because it was written down, and the New Testament is its record; Rome's separate oral deposit, asked to carry purgatory, priestly confession, and the rest, has no early warrant and plays a two thousand year game of telephone against a text that never changed.

1. Athanasius held one conviction through five exiles. What conviction would you hold at that price, and how does a person become that settled?

2. Gregory said Scripture must umpire between rival traditions. Where do you see traditions, even good evangelical ones, quietly acting as the umpire instead?

3. Busenitz honors Athanasius while refusing to make God's plan depend on him. How do we celebrate faithful people rightly without turning providence into biography?
