Who: Leo the Great, also known as Pope St. Leo I (the Great), was Pope from 440-61 AD. Place and date of birth unknown; died 10 November, 461. Leo's pontificate, next to that of St. Gregory I, is the most significant and important in Christian antiquity, as he tried to combat the heresies which seriously threatened church unity even in the West, such as Pelagianism.
What: A defence of the twofold nativity and nature of Christ against the false teaching of a priest called Eutyches. It is a doctrinal letter sent by Pope Leo I in the year 449 to Flavian, Patriarch of Constantinople, on the Church's teaching about the person of Christ.
Why: An apologetic defending the faith to ensure sound teaching is passed on and understood by all to affirm that Christ has two natures, human and divine, united in the one divine Person of the Son of God.

Today's reading is a defence of the faith against certain things that a priest called Eutyches was teaching, written by Pope Leo I.
Eutyches was speaking against the teaching of the Archbishop of Constantinople, Nestorius, who said that the human experiences of Christ were only part of the ‘the man’ which was distinct from the ‘God the Word’ part of Jesus. To combat this, Eutyches went too far in the other direction and declared that Christ was "a fusion of human and divine elements" which created a new, single nature in Jesus, rather than a twofold nature which the Creeds declare. This actually led to himself being declared a heretic also for this belief!
Now Leo is writing against the teaching of Eutyches because it seems that he was unwilling to accept any correction to his doctrine. “But what more iniquitous”, Leo says, “than to hold blasphemous opinions, and not to give way to those who are wiser and more learned than ourself?”
Leo is quite scathing actually, and doesn’t hold back on denouncing the man or his teaching:
Now into this unwisdom fall they who, finding themselves hindered from knowing the truth by some obscurity … thus they stand out as masters of error because they were never disciples of truth...
He goes on to wonder how Eutyches could not have been corrected by others or more in depth study, or even want to change his view when even the the Creeds say otherwise, which is the measure by which all heresies are defeated.
[Has he] not even grasped the rudiments of the Creed? And that which, throughout the world, is professed by the mouth of everyone who is to be born again … By which ... the devices of almost all heretics are overthrown.
He goes on to quote the statements of the Creed, which is confessed by all the Churches, to make his point and contrast with what Eutyches said and taught, which was commonly accepted as the fundamentals of the faith:
He is God from God , Almighty from Almighty, and being born from the Eternal one is co-eternal with Him; not later in point of time, not lower in power, not unlike in glory, not divided in essence: but at the same time the only begotten of the eternal Father was born eternal of the Holy Spirit and the Virgin Mary.
Leo goes through many instances in the New Testament, from the Gospels to Paul's letters, to Old Testament prophecies, to really point out that Jesus was the Word made flesh – and truly flesh, not some deception.
If Eutyches had read all these things closely, “then he would not speak so erroneously as to say that the Word became flesh in such a way that Christ, born of the Virgin's womb, had the form of man, but had not the reality of His mother's body”, which sounds a lot like Docetism, the heresy which was around much more a couple of centuries earlier.
Instead, and in contrast to this, the commonly accepted doctrine on the nature of Jesus is explained by Leo as being, “without detriment therefore to the properties of either nature and substance which then came together in one person, majesty took on humility, strength weakness, eternity mortality...”. In theological terms, this concept of Jesus having two natures in one body has come to be known as the hypostatic union. Leo maintains that Jesus Christ is one person of the Trinity who has two distinct natures which are permanently united together. This letter (or “Tome”) was later recognized by the Council of Chalcedon (451 AD) as a statement of orthodox Christology, which gave rise to the Chalcedonian Creed specifically for this purpose and reason.
I’m going to quote the whole of the Creed here just so people can read it who haven’t before:
We, then, following the holy Fathers, all with one consent, teach men to confess one and the same Son, our Lord Jesus Christ, the same perfect in Godhead and also perfect in manhood; truly God and truly man, of a reasonable soul and body; consubstantial with us according to the manhood; in all things like unto us, without sin; begotten before all ages of the Father according to the Godhead, and in these latter days, for us and for our salvation, born of the virgin Mary, the mother of God, according to the manhood; one and the same Christ, Son, Lord, Only-begotten, to be acknowledged in two natures, inconfusedly, unchangeably, indivisibly, inseparably; the distinction of natures being by no means taken away by the union, but rather the property of each nature being preserved, and concurring in one Person and one Subsistence, not parted or divided into two persons, but one and the same Son, and only begotten, God the Word, the Lord Jesus Christ, as the prophets from the beginning have declared concerning him, and the Lord Jesus Christ himself taught us, and the Creed of the holy Fathers has handed down to us.
But Eutyches kept on which his teaching saying, “I confess that our Lord had two natures before the union but after the union I confess but one”, to which Leo responds by saying that he is “surprised that so absurd and mistaken a statement” was not picked up on by others, and that now this teaching was reaching, "the height of stupidity and blasphemy"!
Leo does end this letter on a positive note though by saying that if Eutyches, “grieves over [his heresy] faithfully and to good purpose, and, late though it be, acknowledges how rightly the bishop's authority” is on these matters, then he can come back into the Church.
All in all, this letter is a very thorough and detailed apologetic and defence of the faith on the nature of Christ in the incarnation, so much that I think it can still stand on it’s own today. I’d recommend anyone interested in this topic to read Leo’s letter in full to really grasp his arguments.

Luke J. Wilson | 25th August 2026 | William Lane Craig
If you’ve been on Christian social media this week, you’ve probably seen it: William Lane Craig — one of the most respected Protestant apologists of our time— flatly denying a core line of the Nicene Creed. In his own words, he does not believe or confess that the Son is eternally begotten from the Father in his divine nature. Human nature, yes. But divine? Nope. For a lot of readers, that’s a jarring sentence. Isn’t “eternally begotten of the Father” literally in the Creed we recite? How can someone who has spent decades defending the resurrection and the existence of God turn around and reject something so central? I want to walk through what’s actually going on here, because it’s more interesting — and older — than a single viral clip suggests. What Craig is actually rejecting The doctrine in question is called eternal generation: the idea that the Son is eternally derived from the Father, “begotten, not made,” sharing the Father’s nature without there ever being a time he didn’t exist. It’s not saying the Son had a beginning; it’s saying the Son’s very being is eternally from the Father, the way light is eternally from the sun. Craig has argued for years, most fully in his paper Is God the Son Begotten in His Divine Nature? (2019), that this idea owes more to Greek philosophical categories borrowed by the second-century Apologists than to anything the biblical writers themselves teach. He calls it a vestige of “Logos Christology” and prefers a model where Father, Son, and Spirit are simply co-equal and co-eternal, without one eternally generating another. William Lane Craig disavows the Nicene Creed Why I think this gets the history backwards Here’s where I’d push back, and where I think this whole debate needs a bit more historical texture than a viral post can give it. Long before Nicaea formalised its language, the earliest post-apostolic Christians were already working with something like what’s called the Monarchy of the Father (or Monarchical Trinitarianism) — a framework that takes the Father’s monarchia (his unique, self-existent source of divinity, or autotheos) seriously as the fountainhead from which the Son is begotten and the Spirit proceeds. This is worth distinguishing carefully from Monarchianism, the second/third-century heresy that collapsed the persons of the Trinity into one another to protect God’s oneness — the Monarchy of the Father is the orthodox opposite of that, affirming three distinct, co-eternal persons while still honouring the Father as their singular source. On this reading, the Son and Spirit aren’t lesser, but they do find the very source of their divinity in the Father — not as effects of a philosophical system layered onto scripture, but as a way of taking John’s own language (the Word who was with God and was God, yet distinct from “the Father”) with full seriousness. That’s the thing I think gets lost when eternal generation gets dismissed as a “leftover.” Logos Christology isn’t an embarrassing accretion — it’s arguably what John 1 is doing from verse one. The Church didn’t import that idea to explain the text; the text seems to be why the Church needed the idea. None of this makes Craig any less serious a thinker, and it’s worth saying plainly: this isn’t the first time he’s stepped outside Nicene orthodoxy — he’s made similar moves on Christ’s two wills (dyothelitism) in the past. But it is, I think, a real departure, not just a “minor unorthodoxy.” Why it matters beyond the argument It would be easy to turn this into another “gotcha” moment — ‘look, even the great apologist gets it wrong!’ I don’t think that’s the right response. Craig has done more than most to defend the reasonableness of the Christian faith to a sceptical world, and disagreeing with him on this doesn’t erase that. But it is a good reminder that ev...
Guest Author | 31st July 2026 | Prayer
Guest Post By Fiach OBroin-Molloy My own roots lie in the Catholic tradition, but my workbench has brought me into contact with Christians whose devotional lives differ from mine. I make Catholic rosaries, Anglican prayer beads and other forms of devotional beads by hand. That work has not taught me that distinctions between traditions do not matter. It has taught me that, beneath those distinctions, many of us know the same difficulty: we want to pray, but our attention is restless. I have travelled, lived and worked in a number of countries, from parts of Africa to countries further east. Again and again, I encountered beads or knotted cords held, counted or carried in prayer. The words, beliefs and purposes were not the same, and I would not flatten them into one vague spirituality. What stayed with me was the recurring human instinct to give devotion rhythm and weight—to let the body help the mind and heart remain present. For a Christian, however, that instinct is gathered into a particular faith—the faith confessed in the creeds. Our prayer is addressed to the God made known as Father, Son and Holy Spirit. It is shaped by Scripture and centred on Jesus Christ, the Word made flesh, crucified and risen. Prayer beads do not broaden that confession into something less definite. At their best, they help us stay with it. A faith that takes flesh seriously Christian prayer is never only an activity of the mind. We speak and sing. We stand, kneel and bow. We fold our hands, make the sign of the cross, and receive bread and wine. The Christian faith does not ask us to escape being embodied creatures. At its centre is the astonishing declaration that the Word became flesh and dwelt among us (John 1:14). Material things are not God, but they can serve our attention to God. That is the modest place in which I understand prayer beads. They do not create faith, improve the words of Scripture or make prayer more sincere. They simply give the hands something quiet to do while the heart and mind try to remain present. As a maker, I think about weight, texture, spacing and movement. A bead should pass naturally beneath the thumb. The cord or chain should be strong enough to be returned to repeatedly. A good set of prayer beads should not continually demand admiration for itself. Its purpose is to become quiet in the hand. Over time, beads polish, wood darkens and metal takes on the small marks of use. I rarely know the prayers that have been said with something I have made, but sometimes its wear tells me that it has been held often. That is a different kind of beauty from newness: not decoration, but evidence of return. What the hands bring to Scripture Lectio Divina invites us to read Scripture slowly and receptively. Luke J. Wilson has written much more fully about its four movements—reading, meditation, prayer and contemplation—and I would not try to redefine that teaching here. What interests me as a maker is the point at which a reader’s hand might support that attention. Most of us have become highly practised at moving quickly through words. We skim messages, headlines and pages, often looking for the next piece of information before we have received the one in front of us. Sacred reading asks something different. It asks us to stay. A bead introduces a small resistance to speed. It marks a pause and gives us somewhere to return when the mind has already hurried ahead. The Anglican prayer beads I make contain a cross, an invitatory bead, four cruciform beads and four groups of seven, often called weeks. I know that structure first through the work of my hands, not because I would presume to tell Anglicans how they ought to pray. What strikes me about it is its spaciousness: there are landmarks, passages and repeated opportunities to return to the cross. One possible practice would be to choose a short passage from the Gospels. At the cross, the reader might remember that Christ is the centre of the reading. ...
Luke J. Wilson | 29th July 2026 | Faith & Reason
��Pilate asked him, ‘What is truth?’ (John 18:38) What is “truth”? A question famously asked by Pilate to Jesus during his trial. Ironically, Pilate was speaking to the embodiment of Truth itself. John 14:6Jesus said to him, ‘I am the way, and the truth, and the life.’ Here’s a little ‘riddle’ to think about while you read this; see if you agree or not: “all truth is fact, but not all facts are truth”. I’ll explain it at the end if you’re confused. Jesus is the ultimate Truth, but in a world and society that is becoming increasingly more relative, how do we test the truth and know what’s real or not? Especially with the sudden rise of AI video and photos getting more and more realistic, that old adage “the camera never lies” is completely false now. This makes sifting and filtering facts from fiction on social media all the more difficult. Memes and images are shared stating claims bluntly and authoritatively as truth, which people just assume are accurate and then share it hundreds of thousands of times. Truth has been replaced by opinion masquerading as truth. “Your truth”, “my truth”, “their truth”. But we can’t just blindly accept everything we see and are told. We must use our brains, check the sources and use our reasoning. God gave us intellect and reasoning to be used. In Isaiah 1:18, God invites us to come and reason together with him. We don’t follow a blind faith, we’re never asked to believe “just because”. The Old Testament is full of times when the historical examples of God’s actions are used as an anchor and reason for faith, and the same is true in the New Testament where we have the Gospels as eyewitness accounts, rooted in history. Paul writes to say that 500 people saw the risen Christ and that many are still alive so you can go and verify it for yourself and that he is passing on what he received from trusted people. The resurrection itself is grounded in it being a real event that if shown otherwise would make our faith “futile” and that we would be people to be most pitied. 1 Corinthians 15:17“If Christ has not been raised, your faith is futile and you are still in your sins.” So with this in mind about our faith being grounded, all the more we should aim to do the same in other aspects of our lives. “Do your own research” is a common mantra online, but that in itself isn’t just Googling something and taking the first result that pops up. Especially now as most search engines give an AI overview first, which is just a compilation of the top results, not anything verified or fact-checked. And top results don’t always mean best results, or even accurate results. It typically just means the best keyworded and SEO-optimised result, which could be anything. To properly research, you must know which are trusted sources, reputable websites as well as looking up people who are experts and authorities in their fields. Now this doesn’t always mean they are right but at least you’ll be better informed to make up your own mind and make decisions based on well-researched information, rather than the first blog you find online, or the most viewed YouTube video with someone yelling “facts” at you. Doing your own research means doing the leg-work in tracing down sources and footnotes and citations to see who said what and where it originated to ensure its faithful and trustworthy, and used in context. The answer and example of the riddle The “Black Swan Problem” Strictly speaking, it highlights the difference between observed facts and absolute truth: The “Fact” (at the time): For thousands of years, every recorded, verified observation of a swan in Europe was white. As far as European zoologists were concerned, “all swans are white” was a well-documented, empirically backed fact. The Truth: Millions of black swans were happily swimming around in Western Australia. The truth was always that black swan...

In early July 2026, Egypt’s Ministry of Tourism and Antiquities announced something pretty amazing: an entire Byzantine-era city, buried beneath the sands of the Dakhla Oasis, had been uncovered almost intact! Streets, homes, bread ovens, a fortress, and at its heart, a fourth-century basilica church. That might not seem very exciting on first glance. But this find deserves a closer look, because it puts flesh on something we usually only encounter in the abstract: what it actually looked like when Christianity took root, house by house, in an ordinary town far from the centres of imperial power. What Was Found The excavation, carried out by an Egyptian mission under the Supreme Council of Antiquities at the Ain El-Sabil site in the New Valley Governorate, roughly 185 miles west of Luxor, has been underway for several seasons. According to Hisham El Leithy, secretary-general of the Supreme Council of Antiquities, the settlement was laid out on a deliberate grid — north-south thoroughfares crossed by east-west streets, forming open squares and public spaces. This wasn’t a huddle of huts; it was a planned town. At the centre of that plan stood a basilica church dating to the mid-fourth century AD, overlooking one of the main streets. Around it, archaeologists found the remains of two watchtowers, a heavily fortified structure with thick defensive walls, and houses with spacious reception halls and vaulted roofs — complete with bread ovens, kitchens, and grinding stones for processing grain. Everyday life, preserved almost exactly as it was left. Two houses stand out that have been identified. One belonged to a man named Tisous,* identified as a church deacon, dating to the second half of the fourth century. The other belonged to a man named Tabibos. Over a thousand years later and we know the name of who owned a house and a home-church; I always find it fascinating! Archaeologists believe Tabibos’s house, which dates to the early fourth century, functioned as a house church before the basilica was ever built. A collection of coins bearing Byzantine emperors, Christian symbols and Latin inscriptions was uncovered during the excavation. (Egyptian Ministry of Tourism and Antiquities via Facebook; Dea Picture Library/De Agostini via Getty Images) There’s also a documentary find that’s easy to skim past but genuinely significant: nearly 200 ostraca — broken pieces of pottery and limestone used as everyday writing material — inscribed in Coptic and Greek. Diaa Zahran, head of the Islamic, Coptic and Jewish Antiquities Sector, described them as recording sales transactions, correspondence, and other mundane details of daily life. Things we rarely get a glimpse into as the mundane rarely makes history. Alongside these, the mission recovered a substantial haul of bronze coins bearing Byzantine emperors and Christian symbols, plus gold coins from the reign of Constantius II (337–361 AD) — coinage that anchors the site’s prosperity firmly within the fourth century. Before the Basilica: The House Church at Ain El-Sabil What makes Tabibos’s house the most theologically interesting part of this discovery is timing. If it predates the basilica and dates to the early fourth century, it sits right at — or just before — the pivot point of Roman-Egyptian Christian history: the years surrounding Constantine’s Edict of Milan in 313 AD, when Christianity moved from a persecuted minority faith to a tolerated, and increasingly favoured, one. A time of transition between a house church and a purpose-built basilica when the threat of persecution no longer loomed over the Church. We know from Paul’s letters that the earliest churches met in homes — Romans 16:5 greets “the church in [Prisca and Aquila’s] house,” and similar greetings appear in 1 Corinthians 16:19 and Colossians 4:15. If we were to imagine how a letter from Paul to this house church might...

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.
