The council of Constantinople
The Nicene Creed finalized
The emperor Theodosius I calls a council in Constantinople in 381 AD, and what comes out of it is the creed that is still recited in churches around the world every Sunday.
The council does two things. It expands the 325 AD Nicene Creed to include the full statement on the Holy Spirit — taking the three words and in the Holy Spirit and extending them into the full pneumatological declaration that Basil's work prepared. And it formally condemns Arianism, Apollinarianism, and Macedonianism in a single synodical decision.
The creed that results — technically called the Niceno-Constantinopolitan Creed, though everyone calls it the Nicene Creed — is the most ecumenical document in Christian history. Roman Catholic, Eastern Orthodox, Anglican, Lutheran, Reformed, and most Protestant traditions all confess it. It is the one formal statement of faith shared by more Christians than any other.
The process is messy. Gregory of Nazianzus opens the council, is pelted with arguments and politics, and resigns before it concludes. The Eastern bishops are deeply suspicious of each other after decades of theological warfare. The Nicene cause wins not by persuasion of its opponents but by the emperor's clear preference and by the accumulated exhaustion of everyone who has been fighting the Arian controversy for fifty-six years.
None of that takes anything away from the creed itself. It was shaped by fifty-six years of suffering and argument and exile and martyrdom.
It is still being said. Right now, in a thousand languages, someone is saying it.
“We believe in the Holy Spirit, the Lord and giver of life, who proceeds from the Father, who with the Father and the Son is worshipped and glorified, who spoke through the prophets.”
— Niceno-Constantinopolitan Creed, 381 AD
“But if the Spirit of him who raised up Jesus from the dead dwells in you, he who raised up Christ Jesus from the dead will also give life to your mortal bodies through his Spirit who dwells in you.”
Fifty-six years from Nicaea to Constantinople. One generation of sustained theological argument, political pressure, exile, violence, and slow persuasion.
The creed that came out the other side was not a compromise. It was a clarification — the best words available for the most important reality imaginable.
When you say it on a Sunday morning, you are saying words that cost fifty-six years and several lifetimes. Athanasius's five exiles are in it. Basil's treatise is in it. Gregory's sermons in a stone-pelted house are in it.
Say it like it cost something. Because it did.
