In Türkiye, not far from Istanbul, is a small town called Iznik. There is no Christian church, but this year Christians around the world are celebrating a significant event that took place here 1700 years ago. In those days, the town was part of the Roman Empire, and had the Roman name Nicaea.
In 325AD, a statement of faith called the Nicene Creed was formulated here, and it is still a standard document for a majority of Christian churches. To find out how it came about, we’ll need to dig into bit of a history.
In the early years of the 4th century AD, Christians in the Roman Empire were a minority group. Under the emperor Diocletian, Christians were persecuted. Church buildings were destroyed, sacred writings were burnt and worship meetings were banned. Christians who refused to sacrifice to the cult of the emperor could be killed. As you can imagine, Christianity was slow to grow in these circumstances.
Then along came Constantine, first as emperor of the western empire, then in 324 of the combined east and west. Critically, Constantine turned from paganism and became a Christian. He was keen to encourage Christian interests, as a political move to help unify his fractured empire. So the Treaty of Milan decreed that all Roman citizens could worship who they liked, without interference from the empire. Christianity didn’t become the official religion then, but it was free from persecution.
Against this background, Christians were still coming to grips with what it meant to be a Christian. The writings of the apostles had been collected and copied, but their contents were mainly spread orally, which made study and interpretation hard. It also made it relatively easy for people to spread ‘false teaching’ that was not scriptural.
One result was that the nature of the relationship between God, Jesus and the Holy Spirit became contentious. In particular, a Christian sect called Arians claimed that Jesus was a created being, not a divine part of a Trinity with God and the Holy Spirit.
Emperor Constantine’s plans for a unified empire needed a united Christian church. So he gathered together over 300 bishops from across the Empire at his summer palace in Nicaea, where he set them to sorting out their differences. Over three months, the bishops tried to prayerfully determine the will of God. One result was the writing of what is now called the Nicene Creed, a statement of faith that is still used by many denominations around the world.
There were several changes to the Nicene Creed in following councils; the text we’ll look at now is a version in common use today. As I read it out, please don’t say it out loud yourselves – I’d like you to concentrate on what the words mean to you.
We believe in one God,
the Father, the Almighty
maker of heaven and earth,
of all that is, seen and unseen.
We believe in one Lord, Jesus Christ,
the only Son of God,
eternally begotten of the Father,
God from God, Light from Light,
true God from true God,
begotten, not made,
of one Being with the Father.
Through him all things were made.
For us men and for our salvation
he came down from heaven:
by the power of the Holy Spirit
he became incarnate from the Virgin Mary, and was made man.
For our sake he was crucified under Pontius Pilate;
he suffered death and was buried.
On the third day he rose again
in accordance with the Scriptures;
he ascended into heaven
and is seated at the right hand of the Father.
He will come again in glory to judge the living and the dead,
and his kingdom will have no end.
We believe in the Holy Spirit, the Lord, the giver of Life,
who proceeds from the Father and the Son.
With the Father and the Son he is worshipped and glorified.
He has spoken through the Prophets.
We believe in one holy catholic and apostolic Church.
We acknowledge one baptism for the forgiveness of sins.
We look for the resurrection of the dead,
and the life of the world to come.
Having come up with this statement, the council condemned anyone who did not agree with what it said; those bishops at the Council who disagreed were banished as heretics. Constantine got what he wanted, but sadly the unified church went on to persecute heretics to a level that matched what Christians had recently suffered under Diocletian.
The Nicene Creed unified the orthodox church with a basic doctrine of belief, and continues to do so. But since then there has been much disunity over non-doctrinal issues, such as governance, traditional rituals and practices, the style and timing of baptism, the date of Easter and so on. There was an early split between the Western Orthodox Church (which largely became what we term Roman Catholic) and the Eastern Orthodox Church. But they both used the Nicene Creed.
In 16th century Europe, there was a huge upheaval called the Protestant Reformation, which saw many people break away from the Roman Catholic Church, not always peacefully. New Protestant groups continued to appear, and there are now hundreds of denominations. They differ in many ways, but they nearly all maintain belief in the doctrine articulated in the Nicene Creed. For example, the Anglican, Methodist and Presbyterian churches, the Salvation Army and many Baptist churches, all recognise the Nicene Creed.
The Creed I read out just now has four ‘We believe’ statements – three focussing on the Trinity, with a single line on the church. It’s that line I’d like to talk a bit more about.
“We believe in one holy catholic and apostolic Church.”
A couple of quick word explanations here.
The term ‘catholic’ is written with a small c – it just means universal church, and does not refer to the Roman Catholic Church.
Apostolic means based on the words and actions of the Apostles, as recorded in the New Testament.
The use of the phrase “We believe” rather than “I believe” was, of course, deliberate. “I believe” was, and is, used in personal statements of faith, especially those declared at baptism. “We believe” is a communal statement made by a group with shared beliefs – originally by the bishops at Nicaea, later by gathered church congregations everywhere.
Remembering that ‘catholic’ means universal, “We believe in one holy catholic and apostolic Church” says that we believe in one church throughout the world, based on the biblical words of the Apostles. It doesn’t say we believe in a particular denomination, but in God’s worldwide church.
Just before his arrest, we hear in John 17 that Jesus prayed for his disciples. “I pray not only for them, but also for those who believe in me because of their message. I pray that they may all be one. Father! May they be in us, just as you are in me and I am in you.”
Jesus’ prayer reminds us that the church is called to be one, and its unity is to reflect the oneness of Jesus with God the Father. We believe in a universal church, because it is God’s church. When we say the Creed, we can feel part of this worldwide community. This means we all have some responsibility to be part of its ministry.
I’m going to read out the Tawa Baptist Statement of Faith, and I’d like you to read it out with me. If you don’t want to, that’s fine.
We believe . .
- In one God in three persons: God the Father, God the Son and God the Holy Spirit.
- In the true humanity and deity of the Lord Jesus Christ, God the Son.
- In the atonement made by the Lord Jesus Christ on the cross for the sin of the world.
- In the resurrection of the Lord Jesus Christ from the dead.
- That salvation and membership in the Church universal is by faith in the Lord Jesus Christ.
- That the Bible is inspired by God and authoritative in matters of Christian faith and practice.
By saying “We believe”, we include ourselves in the global church, as well as in this church of Tawa Baptist. Today, this church has been blessed because Kyle and Izandi have formerly become part of that “We”. We can pray that being part of our church life together will help them grow in their personal faith – indeed for all of us, saying “We believe” helps us to more confidently say “I believe.”
I’d now like to take you back to the modern village of Iznik, Roman Nicaea. One of the bishops present in 325AD wrote that “The most eminent servants of God from all the churches that filled Europe, Africa, and Asia gathered together. One place of worship, as if expanded by God, accommodated the people.”
Over the centuries, the site of this church was forgotten, lost.
Then, in 2014, aerial photographs of the Iznik shoreline got archaeologists very excited. There, close to shore, in shallow water, was the outline of a stone basilica, an early form of church. The building of the church was dated to about 100 years later than the Council of Nicaea, and it disappeared beneath the waters of the lake in an earthquake over 600 years later.
Further excavations revealed the remains of an earlier church under the stone one. It’s not certain, but the date is right for this to be the church the Council of Nicaea met in.
The lake of Iznik has been shrinking due to years of drought, so the ruins of the basilica have gradually got closer to the surface and nearer the shore. You can now stand on the ruins without getting your feet wet. I can’t help wondering if, just as He expanded the church to fit all the bishops in 325, God has revealed that church in time for Nicaea 2025 celebrations.
A few weeks ago, my sister-in-law visited Iznik as part of a Nicaea 2025 tour led by Father Luke Miller, Church of England archdeacon of London. She sent me a photo of the church ruins, where they held a communion service. Later this year, the new Pope Leo is due to meet Patriarch Bartholomew, spiritual leader of the Eastern Orthodox Church, at this very spot. Their joint celebration of the Council at Nicaea is a landmark event in itself.
The church council in 325 aimed for Christian unity, but sometimes it seems that, apart from basic matters of doctrine, unity is still far off. Celebrations of Nicaea 2025 are particularly significant for The World Council of Churches, which for many years has encouraged unity between denominations representing over half a billion Christians worldwide. It may be on a smaller scale, but here in Tawa several churches work together in common witness and service, sharing the unity hoped for in the Nicene Creed.
I’d like to finish by reading some words Father Luke used during his tour to Nicaea.
“Constantine wanted unity. Guided by the Holy Spirit, something extraordinary happened in Nicaea. In all the divisions and stresses of the church, the creed of the fathers of Nicaea remains a bright thread in the frayed fabric of the unity of the church. God is at work still, not to fulfil the desire of a powerful emperor, but to bring us all to the glory of union with Him.”
