Apostolic Constitutions

Introduction

There is a document that has survived the wreckage of centuries, the burning of libraries, the fragmentation of empires, and the fracturing of the Christian world itself — a document so comprehensive, so ambitious, and so revealing that scholars have called it the single most important window into the life of the early church. It was composed in Syria, probably in the late fourth century, drawing on sources that stretch back generations before its final compilation. It speaks in the voice of the apostles themselves, claiming authority from those who walked with Jesus, who broke bread with him, who carried his message to the ends of the known world. And yet, for most modern Christians — even educated, devoted, deeply curious ones — it remains almost entirely unknown.

This is the paradox at the heart of what you are about to explore. We live in an age of unprecedented access to historical information. We can read the Dead Sea Scrolls in translation, study the Nag Hammadi library, trace the development of the biblical canon through detailed scholarly commentary, and reconstruct the liturgical practices of communities that vanished fifteen hundred years ago. And yet the vast compilation known to historians and theologians as the Apostolic Constitutions sits largely outside the popular imagination, confined to academic journals, seminary reading lists, and the footnotes of books about early Christianity. It deserves far better. It deserves to be read, wrestled with, and understood by anyone who wants to know where Christian doctrine, worship, and community life actually came from.

The reason for this neglect is not hard to find. The text is long — eight books covering an enormous range of topics, from the duties of widows to the proper conduct of bishops, from the structure of the Eucharist to the rules governing the reception of converts, from elaborate prayers that echo the Jewish liturgical tradition to disciplinary canons that would not look out of place in a modern legal code. It is, in short, a document that demands a guide. And that is precisely what this book sets out to provide: a clear, thorough, and genuinely engaging introduction to one of the most remarkable texts that early Christianity produced.

Before we go any further, it is worth pausing to ask a question that might seem almost too basic: why does any of this matter? Why should a modern reader — whether a practicing Christian, a student of history, a scholar of religion, or simply someone curious about how the ancient world worked — care about a fourth-century Syrian compilation that most people have never heard of? The answer, it turns out, is layered and surprising.

First, the text matters because it is a primary source of extraordinary richness. Unlike the theological treatises of the church fathers, which tend to address specific controversies and assume a reader already embedded in the debates of the time, this compilation gives us something rarer: a picture of the church as an institution, in motion, governing itself, worshipping, arguing, welcoming strangers, disciplining members, and trying to hold together a community that was spreading rapidly across a diverse and often hostile world. Reading it is not like reading a theological argument. It is more like being handed the operating manual of a living community — complete with its assumptions, its tensions, its ideals, and its very human compromises.

Second, the text matters because so much of what we think of as distinctively Christian — the shape of Sunday worship, the role of the bishop, the structure of baptism, the theology of ordained ministry, the relationship between the church and the Hebrew scriptures, the ethics of wealth and poverty, the treatment of women in community life — has roots that run directly through documents like this one. You cannot fully understand how Christianity became what it is without understanding the process by which early communities codified their practices, and this compilation is one of the most complete records of that process that we possess.

Third, and perhaps most compellingly for the general reader, the text is genuinely fascinating as a human document. It is full of voices — the voice of the compiler, the voices of the sources he drew upon, the imagined voices of the apostles he invoked, and behind all of them the voices of real communities, real bishops, real deacons, real women serving as deaconesses, real converts asking to be baptized, real sinners seeking readmission after falling away. When you read it carefully, you hear an ancient world in the act of constructing something new, something that would endure for millennia, and you hear the arguments and anxieties and aspirations that accompanied that construction.

This book is organized to take you through all of that in a way that is both intellectually rigorous and genuinely readable. We will look at the historical context in which the compilation emerged, the sources it drew upon, the questions it was trying to answer, and the answers it gave. We will examine its theology, its liturgy, and its canon law as distinct but deeply interconnected domains. We will pay attention to what the text reveals about gender, power, community boundaries, and the relationship between Christianity and Judaism at a critical moment in the history of both. And we will ask, throughout, what all of this means for our understanding of Christianity — not just as a historical phenomenon but as a living tradition that is still, in countless ways, shaped by decisions and debates that took place in the fourth century and before.

One more thing needs to be said at the outset, and it concerns the question of authority. The compilation presents itself as the work of the apostles — specifically, as a collection of instructions given by the twelve apostles and Paul, transmitted through Clement of Rome, who was believed in antiquity to have been a companion of both Peter and Paul. This claim is, by the consensus of modern scholarship, a literary fiction. The text was not written by the apostles or by Clement. It is what scholars call a 'pseudepigraphical' work — a text written in the name of revered figures in order to lend authority to its contents. This was a common practice in the ancient world, both inside and outside of Christianity, and it does not by itself tell us anything about the integrity or sincerity of the actual author.

But the pseudepigraphical character of the text raises questions that are worth sitting with rather than dismissing. Why did the compiler feel the need to invoke apostolic authority? What does that tell us about the way authority worked in the early church? What does it mean that communities accepted — or debated, or rejected — documents on the basis of their claimed origins rather than their actual ones? These are not merely academic questions. They go to the heart of how religious traditions sustain themselves across time, how they negotiate the tension between innovation and continuity, and how they construct the past in order to legitimate the present. The compilation is, among other things, a case study in all of these dynamics, and attending to them carefully will enrich your reading of everything that follows.

A World Being Made

To understand what this compilation was doing and why it took the form it did, you need to understand the world in which it appeared. The late fourth century was, by any measure, one of the most turbulent and consequential periods in the history of Western civilization. The Roman Empire, which had persecuted Christians for the first three centuries of the common era, had within living memory become officially Christian. Constantine's conversion in the early fourth century, whatever its precise nature and motivations, had transformed the political landscape of the Mediterranean world with breathtaking speed. By the time our compilation was being assembled — most scholars place its final form somewhere in the 370s or 380s, probably in Antioch or somewhere in the Syrian region — Christianity was not merely tolerated but actively favored by the imperial government.

This transformation brought with it a set of problems that no one had fully anticipated. When Christians were a minority, often a persecuted one, the boundaries of the community were in some sense self-enforcing: the costs of belonging were high enough that membership meant something. Conversion required serious commitment. The structures of the community — the roles of bishop, presbyter, deacon, deaconess, widow, reader, and the various other offices that appear in our text — had developed in response to real needs and were maintained by communities that depended on them for survival. But when Christianity became the religion of the empire, the calculus changed. Conversion became advantageous in worldly terms. The church grew rapidly and in ways that were not always spiritually or ethically coherent. The question of how to maintain community standards, how to define who was truly inside and who was not, how to govern an institution that was simultaneously local and universal — all of these became urgent in new ways.

The compilation responds to this situation with remarkable comprehensiveness. It is, at its core, a manual for running a Christian community at a moment when the stakes of doing so correctly have never been higher. It addresses bishops with elaborate instructions about their character, their duties, and their authority. It addresses deacons and deaconesses with careful attention to their specific roles. It speaks to laypeople about their obligations in worship, in ethics, and in community life. It provides liturgical texts — prayers, eucharistic rites, baptismal ceremonies — of extraordinary beauty and theological depth. And it issues canons, rules, regulations, the kind of practical legal framework that any institution needs if it is going to function across time and geography.

The sources the compiler drew upon are themselves a fascinating story. Scholars have identified at least three major earlier documents embedded in the compilation. The first two books draw heavily on a second-century text known as the Didascalia Apostolorum — the 'Teaching of the Apostles' — which was itself a manual for church life addressed primarily to bishops and their communities. Books three through six continue to draw on and expand this material. Book seven incorporates and transforms an even older text, the Didache, or 'Teaching of the Twelve Apostles,' which is one of the earliest non-canonical Christian documents we possess, possibly dating to the late first or early second century, and which contains some of the most primitive liturgical and ethical material in the entire Christian tradition. Book eight draws on what scholars call the Apostolic Tradition, a document associated with Hippolytus of Rome, which provides detailed instructions for ordination rites and the Eucharist.

What the compiler did with these sources is itself instructive. He did not simply reproduce them. He expanded them, updated them, added theological commentary, introduced new material, and shaped the whole into a coherent — or at least an ambitious — unity. He was, in the language of modern scholarship, a redactor, but a redactor with a clear theological vision and a genuine pastoral concern. He wanted to give the church of his time a comprehensive foundation, something that could serve as an authoritative guide precisely because it claimed to reach back to the very origins of the movement. Understanding this editorial process — seeing where the compiler added, where he changed, where he preserved — is one of the most intellectually rewarding aspects of studying this text, and it tells us as much about the fourth century as about the earlier periods whose materials it incorporates.

The geographical context matters too. Antioch, if that is indeed where the compilation was produced, was one of the great cities of the ancient world and one of the most important centers of early Christianity. It was in Antioch, according to the Acts of the Apostles, that followers of Jesus were first called 'Christians.' It was from Antioch that Paul launched his missionary journeys. It was in Antioch that some of the most consequential theological debates of the early centuries played out — debates about the nature of Christ, about the relationship between Jewish law and Christian practice, about the proper governance of the church. A document produced in this environment would have been shaped by all of these currents, and reading it with an awareness of that context allows you to hear resonances and tensions that might otherwise pass unnoticed.

The theological controversies of the fourth century are particularly important for understanding certain features of the text. The Council of Nicaea in 325 had attempted to resolve the Arian controversy — the debate over whether the Son of God was fully divine or a created being subordinate to the Father — but the controversy continued to simmer for decades afterward. Scholars have noted that certain passages in the compilation seem to reflect a theological position that is not quite Nicene orthodoxy as it would later be defined, and this has been one of the factors in debates about the text's precise date and provenance. Whether the compiler was himself navigating these debates, or whether he was simply transmitting older material that predated the Nicene settlement, is a question that requires careful attention to the text itself — and it is a question that opens onto some of the deepest issues in the history of Christian doctrine.

All of this historical complexity might seem, at first glance, to make the text more difficult rather than more accessible. But the opposite is actually true. When you understand the world the compiler was living in — the pressures he was responding to, the traditions he was drawing on, the controversies he was navigating — the text comes alive in ways that a purely abstract reading cannot achieve. It stops being a collection of ancient rules and becomes something much more interesting: a human response to a moment of profound historical transformation, an attempt to hold together a community that was growing faster than anyone could manage, and to give that community a sense of its own deep roots even as everything around it was changing.

What You Will Find Here

There is a temptation, when approaching a text as comprehensive as this one, to treat it as a kind of encyclopedia — a reference work to be consulted rather than a document to be read. This book resists that temptation, and it asks you to resist it too. The compilation rewards sustained reading precisely because its different parts illuminate each other in ways that are not visible if you dip in and out. The ethical instructions in the early books make more sense when you understand the liturgical vision of the later ones. The canons at the end acquire their full weight only when you have absorbed the theological framework that the earlier books establish. The prayers — some of the most beautiful in all of ancient Christian literature — resonate differently once you understand the community they were designed to form and sustain.

That said, it is worth giving you a sense of the terrain you will be covering. The first two books are, in many ways, the most immediately engaging for a general reader, because they deal with the most fundamental questions of Christian ethics and community life. What does it mean to live as a Christian? How should Christians treat the poor, the stranger, the sinner who has fallen away and seeks readmission? What are the obligations of married people, of widows, of orphans? How should conflicts within the community be resolved? These questions are addressed with a directness and a pastoral warmth that can be genuinely moving, and they reveal a community that was, whatever its institutional ambitions, animated by a serious concern for human dignity and mutual care.

The sections dealing with the clergy — bishops, presbyters, deacons, and the various other offices — are among the most historically significant parts of the text, because they give us our most detailed picture of how the threefold ministry of bishop, priest, and deacon was understood and justified in the late fourth century. The bishop, in particular, emerges from these pages as a figure of extraordinary importance and responsibility: a teacher, a judge, a father, a shepherd, a priest, and a representative of Christ to his community. The language used to describe the bishop's role is sometimes startling in its grandeur, and it raises questions about the relationship between authority and service that have never stopped being relevant to Christian communities.

The liturgical material is, for many readers, the most immediately beautiful part of the text. Book seven contains an extended sequence of prayers that scholars have shown to be closely related to Jewish liturgical forms, offering a remarkable window into the Jewish roots of Christian worship. Book eight contains what is known as the Clementine liturgy — a full eucharistic rite of considerable theological sophistication and literary power. Reading these prayers, you are in contact with something that feels genuinely ancient, genuinely alive, and genuinely connected to the deepest streams of the Abrahamic tradition. Even readers who approach the text primarily as a historical document often find themselves unexpectedly moved by this material.

The eighty-five canons that conclude the eighth book — known as the Apostolic Canons — have had a life of their own in the history of Christianity. Collected, translated, and incorporated into later canonical collections, they became foundational texts for both Eastern Orthodox and, to a lesser extent, Western canon law. They deal with everything from the qualifications required for ordination to the proper handling of church property, from the treatment of clergy who commit serious sins to the regulation of fasting practices. They are, in a sense, the most purely institutional part of the compilation, and yet even here, if you read carefully, you can hear the underlying theological and pastoral concerns that animate the whole project.

Throughout this book, we will be attentive to the voices that the compilation sometimes silences or marginalizes as well as those it amplifies. The treatment of women is a case in point. The compilation acknowledges and regulates the role of deaconesses — women who played a significant role in early Christian communities, particularly in the baptism of adult women and in ministry to women who were sick or in need. But it also reflects anxieties about female authority and public roles that were characteristic of its time and place. Reading these passages requires both historical empathy — an ability to understand why people thought as they did — and critical honesty about what those ways of thinking cost, and cost in particular the women whose voices we can only partially recover.

Similarly, the compilation's treatment of Jews and Judaism is a subject that demands careful attention. The text is deeply indebted to Jewish tradition — its prayers, its ethical framework, its understanding of scripture, its very conception of what a holy community looks like all bear the marks of this debt. And yet it also contains passages of anti-Jewish polemic that reflect the increasingly adversarial relationship between the two communities in the fourth century. Understanding this tension — honoring the debt while being honest about the polemic — is essential for any serious engagement with the text, and it is a theme we will return to at several points in the pages that follow.

What you will not find in this book is a simple celebration of the ancient church as a golden age to be uncritically recovered. The early Christian communities were human communities, with all that implies: they were capable of great generosity and great cruelty, of profound theological insight and narrow institutional defensiveness, of genuine spiritual depth and mundane political calculation. The compilation reflects all of this, and reading it honestly means holding all of it together. The goal is not nostalgia but understanding — and understanding, in this case, means grappling with a text that is at once a monument of early Christian literature and a product of a specific historical moment with its own limitations and contradictions.

There is, finally, something that might be called the spiritual dimension of this encounter — something that goes beyond historical analysis and theological categorization. When you read the prayers in this compilation, when you follow the careful instructions for the baptismal rite, when you hear the bishop described as a mediator between God and the community, you are in the presence of people who believed, with extraordinary intensity, that what they were doing mattered — that the shape of their worship, the structure of their community, the ethics of their daily lives were not peripheral concerns but were, in the deepest sense, the point. Whether or not you share their faith, that intensity is worth encountering. It is worth asking what it would mean to care that much about how a community prays, how it treats its poor, how it welcomes the stranger and disciplines the wayward member. Those are not merely ancient questions.

The pages that follow are an invitation — to read carefully, to think historically, to engage theologically, and to let a remarkable ancient document speak to questions that have not lost their urgency. The church that produced this compilation was trying to figure out how to be faithful in a world that was changing faster than it could fully comprehend. It was trying to hold together a tradition and an institution, a set of beliefs and a set of practices, a memory of origins and a vision of the future. It was, in short, doing something that every generation of every religious community has to do — and doing it with a seriousness and a comprehensiveness that commands respect, whatever our own commitments and conclusions may be. Begin, then, with that respect, and with curiosity, and with the willingness to be surprised. The text will reward all three.

The Apostolic Constitutions

Chapter 1

The apostles and elders, to all those who from among the Gentiles have believed in the Lord Jesus Christ: may grace and peace from Almighty God, through our Lord Jesus Christ, be multiplied to you in the knowledge of Him.

The Catholic Church is the plantation of God and His beloved vineyard, containing those who have believed in His unerring divine religion — who are the heirs by faith of His everlasting kingdom, who are partakers of His divine influence and of the fellowship of the Holy Spirit, who are armed through Jesus and have received His fear into their hearts, who enjoy the benefit of the sprinkling of the precious and innocent blood of Christ, who have free liberty to call Almighty God their Father, being fellow-heirs and joint-partakers of His beloved Son. Hear this holy teaching, you who enjoy His promises, as it is delivered by the command of your Savior and is in full accord with His glorious words. Take care, you children of God, to do all things in obedience to God, and in all things to please Christ our Lord. For if any man follows unrighteousness and does those things that are contrary to the will of God, he will be regarded by God as one of the disobedient heathen.

Chapter 2

Abstain from all unlawful desires and injustice. For it is written in the law: You shall not covet your neighbor's wife, nor his field, nor his male servant, nor his female servant, nor his ox, nor his donkey, nor anything that belongs to your neighbor. All such coveting comes from the evil one. For the man who covets his neighbor's wife, or his male or female servant, is already in his mind an adulterer and a thief; and if he does not repent, he stands condemned by our Lord Jesus Christ, through whom glory be to God forever. Amen.

For Christ says in the Gospel, summing up, confirming, and fulfilling the ten commandments of the law: It is written in the law, You shall not commit adultery. But I say to you — that is, I said it in the law through Moses, and now I say it to you myself — that whoever looks at his neighbor's wife with lust has already committed adultery with her in his heart. Such a man is guilty of adultery who covets his neighbor's wife in his mind. And does not the man who covets an ox or a donkey intend to steal them — to put them to his own use and lead them away? Or again, does not the man who covets a field, and persists in that desire, wickedly scheme how to move the boundary markers and force the owner to give up what is his for nothing? As the prophet says somewhere: Woe to those who join house to house and add field to field, until they have taken away what belonged to their neighbor. Why, he asks, must you alone inhabit the earth? For these things have been heard in the ears of the Lord of hosts. And elsewhere: Cursed is the man who moves his neighbor's boundary marker, and all the people shall say, Amen. And Moses says: You shall not move your neighbor's boundary markers, which your fathers have set. For these reasons, terror, death, judgment, and condemnation from God follow those who act this way.

But for those who are obedient to God, there is one law — simple, true, and living — which is this: Do not do to another what you would hate to have done to you. You would not want anyone to look at your wife with evil intent to corrupt her; therefore, do not look at your neighbor's wife with wicked intention. You would not want your garment taken from you; therefore, do not take another's. You would not want to be beaten, reproached, or insulted; therefore, do not treat anyone else that way.

If anyone curses you, bless him. For it is written in the book of Numbers: He who blesses you is blessed, and he who curses you is cursed. And in the same way it is written in the Gospel: Bless those who curse you. When you are wronged, do not take revenge, but bear it with patience. For Scripture says: Do not say, I will avenge myself on my enemy for the wrong he has done me; instead, accept it, and let the Lord right you and bring vengeance on the one who has injured you. And again, Christ says in the Gospel: Love your enemies, do good to those who hate you, and pray for those who mistreat you and persecute you, and you will be children of your Father in heaven, who makes his sun rise on the evil and the good alike, and sends rain on the just and the unjust. Let us therefore, beloved, attend to these commandments and be found to be children of light by keeping them. Bear with one another, you servants and sons of God.

A husband should not be insolent or arrogant toward his wife, but compassionate, generous, devoted to pleasing his own wife alone, treating her with honor and kindness, and striving to be agreeable to her. He should not adorn himself in ways that might attract another woman. For if you are overcome by such a woman and sin with her, eternal death from God will overtake you, and you will be punished with sharp and bitter torments. Or if you do not commit the act itself, but push her away and refuse her, you are still not entirely innocent — not guilty of the crime itself, but guilty to the extent that your self-adornment enticed the woman to desire you. You are the cause of her being so affected, and of her lusting after you and thereby committing adultery with you in her heart. Yet you are not as guilty as she, because you did not seek her out, nor did you desire her. Since you did not give yourself over to her, you will find mercy with the Lord your God, who has said: You shall not commit adultery, and, You shall not covet.

For if such a woman, upon seeing you or meeting you at an inopportune moment, was struck in her heart and sent to you, but you, as a person of faith, refused her — if she was wounded by your beauty, your youth, and your fine appearance, and fell in love with you — you will still be found guilty of contributing to her sin, having been the occasion of her stumbling, and you will inherit a woe. Pray therefore to the Lord God that no harm may come to you on this account. You are not to please people in ways that lead to sin, but to please God, so as to attain holiness of life and share in everlasting rest.

Whatever beauty God and nature have given you, do not enhance further; rather, modestly tone it down before others. Do not let the hair of your head grow too long, but keep it cut short, lest by carefully combing it, wearing it long, and anointing yourself, you draw to yourself women who are either ensnared or seeking to ensnare. Do not wear overly fine clothing to seduce anyone. Do not, with crafty intent, seek out overly fine stockings or shoes, but only such as are decent and practical. Do not put a gold ring on your fingers. All these ornaments are signs of lasciviousness, and if you pursue them in an indecent manner you will not be acting as a good man should. It is not fitting for you, a believer and a man of God, to let the hair of your head grow long and brush it up, or let it spread out, or puff it up, or by careful combing and braiding make it curl and shine. This is contrary to the law, which says in its additional precepts: You shall not make for yourselves curls or shaved circles. Nor should men destroy the hair of their beards and unnaturally alter the appearance of a man. For the law says: You shall not mar your beards. God the Creator has made such adornment fitting for women, but has determined it is unsuitable for men. If you do these things to please people, in defiance of the law, you will be an abomination before God, who created you in his own image. If, therefore, you wish to be acceptable to God, abstain from everything he hates, and do nothing that is displeasing to him.

Do not be a wanderer or drifter, roaming the streets without good reason to spy on those who live wickedly. Instead, attend to your own trade and work, and strive to do what is pleasing to God. Keep the words of Christ always in your mind and meditate on them continually. For Scripture says to you: You shall meditate on His law day and night — when you walk in the field, when you sit in your house, when you lie down, and when you rise up — so that you may have understanding in all things. Even if you are wealthy and have no need of a trade to support yourself, do not be someone who wanders aimlessly and roams about at random. Instead, go to fellow believers who share your faith, and converse with them about the living words of God.
