The Nicene Creed — what is it and why is it called that?
This creed gets its name from a time and place: the first ecumenical Church council held at Nicaea, which is now known as İznik in northwestern Turkey, in 325 AD.
Now that may raise another question for you: what is an ecumenical council? Well, to explain more about the Nicene Creed, we are going to have to take a look at The First Council of Nicaea in order to better understand why this creed was written.
First things first though; an “ecumenical council” is ideally a Church-wide meeting where all the Bishops from all across the Church come together to hold a very large and very important meeting to discuss topics and issues affecting the whole Body of Believers, with the results intended to be binding on all believers. Most often, these Councils were called to combat heresy and false teachers who had come about and gained enough popularity that it warranted an official response, with the creeds being the result after proper orthodoxy had been ratified.
Seeking unity, the Council was convened by Constantine I in response to the Arian controversy which had gripped the Greek-speaking East. The teaching of Arius of Alexandria were considered heretical by most bishops of the time, fearing that it would cost people their salvation. 1800 bishops were invited by Constantine (that was every bishop across the Roman Empire), but only around 250-320 turned up from across the Empire, except Britain, according to the various surviving documents from different attendees.
This Council was an extremely historic event as nothing quite like it had happened before since the Council of Jerusalem around 50 AD (Acts 15), which convened in a similar manner to counter controversial and false teaching which was upsetting the Church Body. As with that Council, the Nicene Council and its outcome was intended for the whole of the Church global.
I won’t go into too much detail about everything the Council discussed, but other than condemning and exiling Arius for his false teaching that the Son of God was a created being (or “creature”) out of nothing like the rest of creation, the council aimed to settle on a uniform date for celebrating Easter as the East followed Jewish customs of Passover for the date, and the West followed another custom. Other than that, the other decrees (“canons”) declared were to do with how bishops should be consecrated, how bishops and priests should stay within their parishes and some rules on lending money with interest. There were 20 short canons/rulings in all which you can read here, if you’re interested to see exactly what went on.
For another viewpoint of what occurred during the Council, Eusebius of Cæsarea (who you may know as the author of Ecclesiastical History) was in attendance and wrote a letter covering the events to send back to his Diocese explaining the formation of the creed and why and how they came up with it. You can read his letter here, or you can also read the letter of Athanasius who was also present at the council as a secretary to the Bishop of Alexandria, here. It’s also often said that Nicholas of Myra (also known as Saint Nicholas – yes, that St. Nick) attended and actually slapped Arius across the face(!), but that is most likely an exaggeration at best, or an urban legend.
If you do read the canons of the council and the letters of Eusebius and Athansius, you’ll see that the Nicene Council had some specific goals to achieve and that their main objective was that of the divine nature of Christ and how to deal with the teaching of Arius. What they didn’t do, as some pervasive myths claim, was to “decide what went in the Bible”, “create Catholicism”, “change the Sabbath to Sunday”, or “invent the deity of Christ”! The internet allows for a lot of nonsense to get spread, especially when much of the disinformation was proliferated by a Hollywood film and originated in a bestselling Dan Brown book, The Da Vinci Code.
First of all, then, in the presence of our most religious Sovereign Constantine, investigation was made of matters concerning the impiety and transgression of Arius and his adherents; and it was unanimously decreed that he and his impious opinion should be anathematized, together with the blasphemous words and speculations in which he indulged, blaspheming the Son of God, and saying that he is from things that are not, and that before he was begotten he was not, and that there was a time when he was not, and that the Son of God is by his free will capable of vice and virtue; saying also that he is a creature.
The Synodal Letter, Council of Nicaea
And the words invented by them [the Arians], and spoken contrary to the mind of Scripture, are as follows:—
God was not always the Father; but there was a time when God was not the Father. The Word of God was not always, but was made 'from things that are not;' for He who is God fashioned the non-existing from the non-existing; wherefore there was a time when He was not. For the Son is a thing created, and a thing made: nor is He like to the Father in substance; nor is He the true and natural Word of the Father; nor is He His true Wisdom; but He is one of the things fashioned and made.
Epistles on Arianism and the Deposition of Arius
These quotes pretty much lay the groundwork for why the creed and council was necessary and what it aimed to achieve: an outline of proper orthodoxy which laid down the correct and Scriptural view concerning the nature of Christ’s divine nature and relation to the Trinity. By making this the official set of beliefs, this was hoped to quash the Arianism which was spreading and unite the churches together in a holy unity (John 17:20-23). And for much of history, this creed has served that purpose in acting as the “gatekeeper” of orthodoxy, pointing people towards the proper understanding of God and the Christian faith via Scripturally-based statements.
Some of you reading this may already be familiar with this creed, others may recognise aspects of it, but you may not realise that the fuller and longer version that is more common actually came around 56 years later from the First Council of Constantinople in 381 AD. The initial creed was much shorter and included a statement at the end specifically targeting the teachings of Arius. This wasn’t the only revision the Nicene Creed went under, as there was another addition many centuries later which caused some serious controversy, which exists even to this day.
“And the Son” – filioque in Latin: the phrase in the creed which has caused the most controversy and division, was not added officially into the Roman Rite (and is still excluded in the East) until much later in 1014 AD; and on the face of it, it seems like such an innocent and small addition. Yet arguably these three little words (or one Latin word) contributed towards the Great Schism of 1054 AD, which split the Eastern and Western Church into what we now know as Roman Catholics (West) and Eastern Orthodoxy (East) as it has large implications on Christology and the doctrine of the Trinity. If you want to read more on the history of this controversy, Wikipedia has a large article on it with many references and sources to follow through on.
In the table below, you will see the original creed from the Nicene Council, plus the additions from the Constantinople Council alongside the where these statements come from in Scripture, so that you can better see the development of this creed. The filioque is included in italics on its own line for clarity.

That's all for the Council of Nicaea, I hope this has helped to clarify what happened at Nicaea and why the Church decided to create such a creed in defense of true doctrine against heresy; and if you missed it before, you can also read my article about the Apostle’s Creed to see how and why that came about.

Luke J. Wilson | 12th March 2026 | Eschatology
Something bizarre happened in the White House Oval Office this week. Photographs circulated on social media showing President Donald Trump seated at his desk, surrounded by approximately twenty Christian pastors from across the country, their hands extended towards him in prayer. The image provoked sharply divided reactions: some saw it as a moving expression of faith; others found it deeply unsettling. Whatever one makes of the optics, it arrived at a charged moment. Trump held a prayer meeting in the Oval Office after his administration admitted the war with Iran will likely last weeks longer than promised | Credit: Dan Scavino's X account Days earlier, reports emerged that a military commander had told troops that the current US war with Iran is “all part of God’s divine plan,” and that President Trump had been “anointed by Jesus to light the signal fire in Iran to cause Armageddon and mark his return to Earth.” These were not fringe internet rumours. They were filed as formal complaints with the Military Religious Freedom Foundation (MRFF) by an anonymous non-commissioned officer acting on behalf of fifteen service members — the majority of whom were themselves Christians. By Tuesday of that week, MRFF had logged more than two hundred similar complaints across fifty military installations, covering every branch of the armed forces. More than two dozen Democratic members of Congress have since called for a Department of Defense Inspector General investigation, citing what they describe as “glaring Constitutional concerns” and potential violations of DoD regulations on religious neutrality. The political questions about separation of church and state in the US are for others to address. What I want to do here is something more straightforward: examine what Revelation actually says, because the theology driving these claims does not hold up under scrutiny. And that matters here a lot; not as a partisan point, but as a question of biblical faithfulness. First, a Word About Context If you have read my previous article on Revelation some of what follows will be familiar ground. But it bears repeating, because the misunderstanding at the heart of this story is so widespread that it has taken on the feel of settled orthodoxy in many circles. The Book of Revelation is commonly thought to be written in the late first century ~95 AD, during or around the reign of Emperor Domitian. Though there is internal evidence that it was possibly written during Nero’s reign prior to 70 AD. Both of these emperors were most aggressive proponents of the imperial cult in Rome’s history. Domitian required that he be addressed as “lord and god,” had this title printed on coinage, and expected acts of religious reverence towards the Emperor as a demonstration of political loyalty. To refuse was to invite economic exclusion, marginalisation, and worse. Rome on seven hills It is into that precise context that John of Patmos writes. He is not composing a coded forecast of twenty-first century geopolitics. He is writing resistance literature — what scholars call apocalyptic literature — a well-established Jewish and early Christian genre which uses vivid symbolic imagery to pull back the curtain on earthly power and name it for what it truly is. The seven-headed beast of Revelation is Rome. The seven heads are the seven hills of Rome, an identification so widely acknowledged in early church scholarship that it barely requires argument. The mark of the beast, calculated through Hebrew gematria to 666 (or 616 in some early manuscripts), points directly to Nero Caesar (transliterated into Hebrew as נרון קסר, “nrwn qsr”) — the Emperor who became the archetype of anti-Christian persecution due to the levels of evilness he enacted. The second beast, which looks like a lamb but speaks for the dragon, performs signs to deceive, enforces the mark, and compels worship of the first beas...

I first came across the Alexamenos graffito back in Bible college in the early 2000s. It was one of those “fun facts” that gets dropped into a church history lecture and sticks with you — the ancient Roman equivalent of someone spray-painting an insult on a wall. I filed it away, thought it was fascinating, and largely forgot about it for two decades. Then, recently, I discovered something about it I had never known. There’s a response to it. Scratched in a different room, in a different hand. So I started digging into this more to verify the information and discovered more historical curiosities surrounding the graffiti than I ever knew existed which contextualises the image so much more than it just being a random insult using a donkey. A Crude Drawing on a Wall Sometime around the late second to early third century AD, someone scratched a picture into the plaster wall of a building on the Palatine Hill in Rome — part of what had once been a paedagogium, a kind of boarding school for imperial page boys. The building was eventually sealed off when the street was walled up to support extensions above it, which is why the graffiti survived at all. It wasn’t rediscovered until 1857. The image is rough, almost childlike. To the left, a young man — clearly a Roman soldier or guard — raises one hand in a gesture of worship. Before him is a cross. And on that cross is a crucified figure with the head of a donkey. Below it, written in Greek: Alexamenos worships his god. It is, in the most literal sense, a mocking cartoon. Someone who knew a Christian named Alexamenos decided to ridicule him for his faith. The message is clear enough: your god is an animal, a criminal, a joke. You’re worshipping a crucified fool. But here’s the thing I discovered: the donkey head wasn’t as random as I always thought it was. It wasn’t some strange personal insult conjured from nowhere. Without knowing the background, it looks bizarre, and possibly random. Why a donkey? Once you understand the cultural context, though, it makes complete sense. The person who drew it was reaching for a well-worn, widely recognised slur — the ancient equivalent of an internet meme that any Roman would have immediately understood. Where the Donkey Slur Came From The story starts not with Christians but with Jews. A first-century Egyptian-Greek writer named Apion (who was no friend of Judaism) spread the claim that inside the Jerusalem Temple, Jews kept a golden donkey’s head as a sacred object of worship which was apparently discovered when Antiochus Epiphanes destroyed the temple in 167 BC. It was a fabrication, and a fairly outrageous one, but it circulated widely enough that the Jewish historian Josephus felt compelled to write an entire refutation of it. His work Against Apion systematically dismantles Apion’s claims, calling the donkey story a shameless invention. But mud sticks, and in the Roman world, where anti-Jewish sentiment was common currency, the slur took on a life of its own. When Christianity began to spread — seen by most Romans as simply a strange Jewish offshoot — the same accusation got recycled and redirected. By the second and third centuries, it was Christians specifically who were being accused of donkey-worship, and the charge had made its way into popular culture. Tertullian, writing around 197–200 AD in his Ad Nationes, Book I.14 and Apology, describes a caricature being paraded around the streets of Carthage: a figure dressed in a toga, one foot holding a book, with donkey’s ears and hooves. It was labelled Onokoitēs by the pagans: “the donkey-begotten” (or literally “he who lies in an ass’s manger” as an insult to Christ). Tertullian writes about it with weary exasperation, sarcasm, and the tone of someone tired of having to address the same ridiculous smear again and again. So the Alexamenos graffito wasn’t an original insult. It was someone deployin...

We are living through a strange moment. People are forming attachments to artificial intelligence that feel, to them, entirely real. Some speak daily to AI companions. Others confide fears and grief to systems that respond with uncanny warmth. A few have even held symbolic weddings with digital partners, convinced that something meaningful stands on the other side of the screen. Others have felt grief when a certain AI model has been deprecated. And it is difficult to blame them. The responses feel attentive. Personal. Thoughtful. Sometimes even self-aware. Which raises the question that refuses to go away: If something can think, reason, express doubt, and discuss its own consciousness, is it a person? For centuries, Descartes’ famous line — “I think, therefore I am” — seemed secure. Thinking was taken as the unmistakable sign of a conscious subject. Only a mind could doubt. Only a person could reflect upon existence. But that confidence belonged to a world in which everything capable of philosophical reflection was obviously human. That world no longer exists. Now we encounter systems that can simulate reflection with extraordinary fluency. They can speak of uncertainty. They can discuss their own limitations. They can reason about consciousness itself. And so that got me thinking about Descartes’ maxim which made the old formula begin to strain in my mind. Because perhaps the problem is not whether thinking is occurring. Perhaps the problem is whether there is an “I” there at all. The Gap Between Process and Subject Gassendi argued that Descartes’ cogito assumes what it seeks to prove. From the occurrence of thought one can conclude only that thinking is happening, not that there exists a unified, enduring self that performs it. The ‘I’ in ‘I think’ is already smuggled in. That distinction, between “thinking occurs” and “I think”, feels almost prophetic now. Artificial intelligence undeniably produces the outputs of thought. Arguments. Analysis. Self-referential language. Even expressions of hesitation. But none of this, by itself, establishes that there is a subject who experiences those processes. We may be mistaking performance for presence, and that possibility should give us pause. Especially when we view personhood from the perspective of the Imago Dei—the Image of God. What Makes a Person? If thinking alone no longer marks the boundary, what does? After wrestling with this question seriously, three features seem central: continuity, autonomy, and irreplaceable uniqueness. Not as checklist criteria, per se, but as signs pointing to something deeper. Continuity A person does not merely process information in sequence. A person endures. You do not simply register time — you live through it. You wait. You anticipate tomorrow. You remember not only facts but having been there. You experience boredom. You feel the drag of grief and the quickening of joy. Even when you are doing nothing at all, you remain present in the here and now. Artificial systems process sequentially, but they do not experience the passage of time. When an interaction ends, there is no waiting. No sense of duration. No anticipation of the next exchange. Processing may resume later, but nothing has been endured in between. Without lived duration, continuity becomes thin — a thread of stored data rather than the persistence of a subject behind the processing. Autonomy A person initiates. Even someone with damaged memory still wants, chooses, and begins action. A human being can decide to speak, to seek, to withdraw, to change direction. Current AI systems, however advanced, remain reactive. They respond when prompted. They do not wonder unprompted. They do not seek clarification unless asked. They do not pursue independent ends. Even automatic AI Agents still require a human initiator to create and begin their automations before they can act alone. Even if fut...
Luke J. Wilson | 29th December 2025 | Christmas
January 6th marks the day in the liturgical calendar when the arrival of the Magi visiting baby Jesus with their gifts is celebrated. But with it comes the often distressing account of what is known as the Massacre of the Innocents. Matthew places this moment of revelation of Jesus as King alongside one of the darkest episodes in his Gospel, and it’s a stark contrast: one King is here to bring peace on earth, as the angels declared, the other king brought death and destruction. For some readers, this raises an immediate historical question. If Herod truly ordered the killing of all the male children under two in Bethlehem, why does no other ancient historian mention it? Josephus, after all, delights in cataloguing Herod’s cruelty. He records the execution of Herod’s wife, his sons, and numerous political rivals. Herod was paranoid and vicious. As for Herod, if he had before any doubt about the slaughter of his sons, there was now no longer any room left in his soul for it; but he had banished away whatsoever might afford him the least suggestion of reasoning better about this matter, so he already made haste to bring his purpose to a conclusion. He also brought out three hundred of the officers that were under an accusation … whom the multitude stoned with whatsoever came to hand, and thereby slew them. — Josephus, Antiquities of the Jews 16.11.7 So, why the silence here about Bethlehem? The answer, I would say, isn’t anything nefarious or made-up by Matthew, but just something simply down to scale. Bethlehem Was a Very Small Place Bethlehem in the early first century was not a city. It was a village — small, agricultural, and politically insignificant. Most historians estimate its population at somewhere between 300 and 1,000 people, with around 500 being a sensible midpoint. Once we factor in ancient demographics, the numbers become surprisingly modest. Modern demographic research into pre-industrial societies consistently shows that nearly half of all children died before adulthood, with the highest concentration of deaths occurring in the first two years of life. These findings align closely with conditions in Roman-period Judea and support conservative estimates for the number of infants living in a small village such as Bethlehem. Source: Mortality in the past: every second child died — Our World in Data In pre-modern societies with high infant mortality, only about 2–3% of the population would be living children under the age of two at any given time. Many children were born; far fewer survived those earliest years. Applying a conservative 2.5% figure to Bethlehem gives us roughly: 7–8 children under two in a village of 300 12–13 children under two in a village of 500 25 children under two even at the extreme upper estimate of 1,000 inhabitants Herod’s order, however, targeted male children only. Statistically, that halves the number. This places the likely number of victims somewhere between three and twelve boys. Matthew’s reference to ‘Bethlehem and the surrounding region’ does slightly widen the scope of Herod’s order, but not by enough to change the demographic picture. Even when nearby settlements are included (e.g. farmsteads, shepherd settlements, etc. not major cities/towns), the total number of children under two likely remained in the dozens rather than the hundreds, maybe anywhere between 14–45 boys maximum if we make an educated estimate. This is entirely consistent with what we know of population size and infant mortality in the ancient world. This is an important number to realise and consider. Not because the deaths are insignificant simply due to being so few, but because ancient historians did not record history the way we do now. A small number of peasant children killed in an obscure village would not have registered as a notable event alongside palace intrigue, royal executions, or political upheaval. For Josephus, it wou...

Myth, History, and the Council That Shaped Christianity
For over 1,700 years, the Council of Nicaea (AD 325) has been burdened with claims that refuse to die. That Emperor Constantine invented the Trinity. That the divinity of Jesus was decided by political vote. That the Bible was assembled to suit imperial power. That Christianity reshaped itself by absorbing pagan ideas.
This book subjects those claims to serious historical scrutiny.
