Introduction: What Is Christian Ethics?

“Just Tell Me the Rules”

A young woman called Marina once came to see her parish priest with a list. She was twenty-two, newly serious about her faith after a few unserious years, and she had come armed. On one side of the page she had written the things she was fairly sure were forbidden. On the other, the things she hoped might be permitted. She had questions about clothing, about a relationship, about how much of her salary she was obliged to give away, and about whether a particular film was acceptable.

“Just tell me the rules, Abouna,” she said. “I’ll follow them. I just need to know what they are.”

The priest read the list carefully, which she had not expected, and then he put it down and asked her a question she had not prepared for.

“Marina,” he said, “what do you want to become?”

She said she did not understand.

“You have written down what you want to do,” he said. “I am asking what you want to be. In thirty years, when your children are grown and your parents are gone and you have lived a whole life — what kind of person do you want to have become? Start there. Then we can talk about the film.”

That conversation contains the whole of this introduction. Marina’s instinct was not wicked. It was the instinct of someone who wanted to please God and did not know how, and the Church has always given real answers to questions like hers. But she had assumed that the Christian moral life is essentially a list of permissions and prohibitions, and that assumption, held alone, will eventually exhaust or embitter almost everyone who holds it. Christian ethics contains commandments. It is not made of commandments. It is made of a person and of what happens to human beings who come near Him.

Some Words We Need

Let me define four words at the outset, because they are used loosely in ordinary speech and precisely in this book.

Morality is the actual pattern of right and wrong conduct: what people do and whether it is good.

Ethics is the disciplined reflection on morality: why an action is right or wrong and how we can know.

Moral theology is what Christians call ethics when it is done in the light of revelation — that is, in the light of what God has told us about Himself, about us, and about the purpose of our existence.

Asceticism (from the Greek askēsis, meaning training, as an athlete trains) is the practical discipline by which a Christian’s desires, habits, and body are gradually re-ordered towards God. This word matters enormously in the Coptic tradition, and it explains something that puzzles outsiders: why an Orthodox Christian will speak in the same breath about fasting from cheese and about forgiving an enemy. The two belong to a single project. Small disciplines train the will for large ones. A man who cannot say no to a plate of food at noon should not be confident of saying no to a much heavier temptation at midnight.

Is Moral Truth Real?

Chapter 1 treats this question in full. Here I state only the position from which the book is written.

Christians hold that moral truth is objective — that is, that some things are genuinely right and genuinely wrong independently of whether any individual, culture, or era recognises it. When we say that the enslavement of human beings was wicked, we do not mean that we happen to dislike it. We mean that it was wrong while it was legal, wrong while it was profitable, wrong while respectable people defended it from pulpits, and wrong in every society that ever practised it. This is not arrogance. It is the only way to make sense of moral progress at all. A society cannot become better unless there is a standard it is moving towards, and that standard cannot itself be simply whatever the society currently thinks.

The opposite view, moral relativism, holds that moral judgements are true only relative to a culture or a person. It is a widely repeated view and a very difficult one to actually live in. The person who says “that’s just true for you” about the treatment of the vulnerable does not usually say it about their own treatment when they are the vulnerable one.

God as the Foundation of Goodness

Where does moral truth come from? The Christian answer is that it is grounded in God — not as an arbitrary legislator issuing decrees, but as the source and standard of goodness itself.

An ancient objection, first recorded in Plato’s dialogue Euthyphro, puts the difficulty sharply: is an action good because God commands it, or does God command it because it is good? If the first, then goodness is arbitrary, and God might have commanded cruelty. If the second, then goodness stands above God, and He is merely its messenger.

The classical Christian answer refuses both horns of this fork. Goodness is neither above God nor arbitrarily decided by Him: goodness is God’s own nature. He does not consult a standard, and he does not invent one. His commands flow from what He eternally is. “God is love” (1 John 4:8, NIV) is not a description of His mood but of His being. This is why He cannot command cruelty — not because a higher rule forbids Him, but because it would be a contradiction of Himself. Chapter 1 examines this argument in detail, along with its critics.

It follows that God’s commandments are not tests of obedience arbitrarily imposed, like a parent demanding a child hop on one leg to prove loyalty. They are descriptions of the shape of a life that works. The prohibition of adultery is not a restriction placed upon an otherwise excellent activity; it is a warning about something that destroys people, told in advance by someone who knows.

Natural Law and the Human Conscience

If God made the world, then His purposes are to some extent legible in it — in human nature and in the structure of things. This is what Christian tradition calls natural law: the moral order that human beings can perceive, however dimly, by reason and conscience, without special revelation.

St Paul appeals to it. He writes that Gentiles who do not possess the Law of Moses nevertheless show that its requirements are written on their hearts, their consciences bearing witness (Romans 2:14–15). This is why the fundamental moral intuitions of humanity converge to a remarkable degree. No culture has ever admired cowardice in battle, treachery to friends, or cruelty to one’s own children. Cultures differ about whom to include in the circle of obligation, sometimes horrifically; they differ far less about what obligation looks like once someone is inside it.

Conscience is the faculty by which a person perceives the moral quality of a particular act. It is real, God-given, and to be respected. It is also, in fallen human beings, damaged. A conscience can be:

• well-formed, when it has been trained by Scripture, the teaching of the Church, wise counsel, and honest self-examination;
• uninformed, when it has never been taught, which is a common and forgivable condition;
• weak or scrupulous, when it condemns things that are not sins, producing anxiety, exhaustion, and sometimes a crippling perfectionism that has nothing to do with holiness;
• hardened, when repeated choices have gradually silenced it so that the person genuinely no longer feels what they once felt.

Because conscience can err, we cannot simply say “follow your conscience” and stop. A Christian is obliged to form the conscience as well as to obey it. But we must add something the Church has always taught and which is easy to forget: a person must never act against a sincere conscience, even a mistaken one, because to act against your conscience is to train yourself to ignore it. The right response to a mistaken conscience is to educate it, not to override it. Chapter 3 develops this at length, including the delicate pastoral question of the scrupulous believer who confesses the same non-sin every week.

The Image of God and the Dignity of the Human Person

At the foundation of Christian ethics stands one sentence from the first page of the Bible: “So God created mankind in his own image” (Genesis 1:27, NIV).

Everything else rests here. To be made in God’s image means, at minimum, that a human being possesses reason, freedom, moral responsibility, creativity, and above all a capacity for relationship with God. The Fathers debated exactly where the image resides — St Gregory of Nyssa located it especially in the mind’s capacity to know God and in human freedom — and taught that the image is not a static stamp but a living likeness meant to grow. [1]

Three consequences follow, and they run through this entire book.

First, human dignity is intrinsic, not earned. It does not increase with intelligence, health, productivity, virtue, or beauty, and it does not decrease with their loss. A person with advanced dementia is not a diminished human being. A prisoner convicted of terrible crimes has not forfeited his humanity, though he may justly have forfeited his liberty. An embryo, a refugee, an elderly widow in a care home, and a rival on the other side of a war are all of the same value, and it is exactly the same value as yours.

Second, dignity is universal. The image is in every human being without exception — every ethnicity, every class, both sexes, the healthy and the disabled, the believer and the atheist, our friends and our enemies. St Gregory of Nyssa drew the conclusion with startling force in a sermon on Ecclesiastes, arguing that to buy and sell a human being is to claim ownership over one who bears the image of God and that the price of such a person could only be the whole of creation. [2] That was written in the fourth century, in a society where slavery was universal and unquestioned. The Church did not always live up to its own teaching — Chapter 32 tells that painful story honestly — but the teaching was there, and it was there because of Genesis 1:27.

Third, the image is the reason love of neighbour is not optional. St John Chrysostom, preaching to a wealthy congregation, insisted that a Christian who honours the chalice on the altar and steps over a starving man at the door has misunderstood both. [3] You cannot venerate the image of Christ in an icon and despise it in a person.

What Went Wrong: Sin and the Wounded Will

If human beings bear God’s image and moral truth is knowable, why is human history what it is?

The Christian answer is the doctrine of the Fall. Humanity, made for communion with God, turned away, and the consequence was not merely a legal penalty but an ontological wound — a disordering of human nature itself. Death entered. The mind was darkened, the desires disordered, the will divided against itself.

Here the Coptic and wider Orthodox tradition has a particular emphasis that is worth stating carefully, because it shapes everything that follows. In much Western theology, especially in its popular forms, sin has been understood primarily in legal categories: a crime, a debt, a violation requiring punishment. The Eastern tradition does not deny that sin is a real offence against God, but it puts the accent elsewhere: sin is a sickness, a corruption of a nature made for God, and salvation is therefore healing. St Athanasius, in On the Incarnation, presents the whole work of Christ in these terms — humanity was returning to the nothingness from which it came, corrupted and disintegrating, and the Word took flesh to arrest that corruption from within. [4]

This is not a small difference of vocabulary. It changes how the Church treats the sinner. If sin is only a crime, the appropriate institution is a court. If sin is also a sickness, the appropriate institution is a hospital, and confession is closer to a consultation than to a trial. This is why an Orthodox priest hearing a confession is not primarily a judge assessing guilt but a physician assessing a wound — asking not only what you did but also how this began, what feeds it, and what will actually heal it.

St Paul described the divided will with a candour that has comforted Christians for two thousand years: “For what I do is not the good I want to do” (Romans 7:19, NIV). Every honest person recognises this. We are not simply wicked, and we are not simply good. We are fractured, and we know it, and we cannot repair ourselves from the inside.

Two errors must be avoided. The first is to treat human beings as totally depraved in the sense that nothing good remains — this is not the Coptic Orthodox view. The image of God in us is defaced, not erased, and genuine goodness in unbelievers is real goodness, not a counterfeit. The second is to treat sin as merely a series of unfortunate incidents which better effort would fix. That underestimates the depth of the wound and leads either to pride when we are doing well or to despair when we are not.

What God Has Done: Grace and Transformation

Christian ethics is not, at bottom, a demand. It is a response to a rescue.

The Word of God became man. He took a real human body, a real human mind, a real human will. He was tempted in every respect as we are (Hebrews 4:15), which means that when Scripture speaks of His sinlessness, it is not describing someone for whom obedience was easy. He died a death He did not deserve and rose, and in rising He broke death from the inside. At Pentecost the Holy Spirit was poured out so that what Christ accomplished for us might become active in us.

St Athanasius summarised the purpose of the Incarnation in a sentence that has become the watchword of the Alexandrian tradition: God became man so that man might become god—that is, that human beings might be made partakers of the divine nature (2 Peter 1:4) by grace, without ever ceasing to be creatures. [5] This is what Orthodox theology calls theosis, or deification. It is not a claim that we become additional gods. It is the claim that the goal of human existence is nothing less than real union with God, in which we are transfigured while remaining ourselves, as iron placed in fire becomes glowing and hot without ceasing to be iron.

Everything in Christian ethics is orientated towards this. Holiness is not the price of admission; it is the shape of the destination, begun now. And because it is God’s work, we may say two things at once that seem contradictory and are not:

• We are saved by grace, not by our moral performance. Nobody earns God’s love, and the effort to do so is not humility but a subtle pride.
• Grace does not leave us as we are. A faith that produces no change in how a person treats their spouse, their money, and their enemies is not the faith the New Testament describes (James 2:17).

The Coptic tradition holds these together by refusing to separate faith from life. We do not obey in order to be loved. We obey because we are loved, and because love that changes nothing is only a feeling.

Virtue, Character, and Habit

Marina’s priest asked what she wanted to become, and he was standing in a very old tradition.

Virtue is a settled disposition to do good — not an isolated act but a stable quality of character. Classical philosophy identified four cardinal virtues: prudence (practical wisdom, the ability to see what a situation actually requires), justice (giving each their due), fortitude (courage, including the courage to endure), and temperance (self-mastery in the face of desire). Christian tradition received these and added the three theological virtues, which are gifts rather than achievements: faith, hope, and love (1 Corinthians 13:13).

The Desert Fathers refined an analysis of the passions — the disordered movements of the soul that drive us: gluttony, lust, avarice, anger, dejection, listlessness (acedia), vainglory, and pride. This scheme, developed by Evagrius and transmitted westward through St John Cassian, who learned it in the Egyptian desert, later became the “seven deadly sins". Its Egyptian origin is not incidental. The monks were the first great empirical psychologists of the Christian world, and their observations about the mechanics of temptation — how a thought arrives, how it is entertained, how consent is given, how a habit forms, and how a habit becomes a captivity — remain more useful than most modern writing on the subject. Chapter 4 sets out this analysis in detail.

Two practical points deserve emphasis here.

First, virtue is formed by repetition. Nobody becomes patient by admiring patience. You become honest by telling the truth on the small occasions when a lie would be easier and nobody would ever know. This is why the Church prescribes disciplines — fasting, fixed hours of prayer, almsgiving, regular confession, and the Eucharist — rather than merely urging good intentions. Character is built the way muscle is built.

Second, motive matters, and so does the act. Some modern ethics attend only to consequences; some only to rules. The Christian tradition asks three questions of any action: What is the act itself? What is my intention? What are the circumstances and likely consequences? A good motive does not make a wrong act right — one may not tell a serious lie in court out of loyalty to a friend. And a right act done from a rotten motive is spiritually worthless — Christ warned against almsgiving performed to be admired (Matthew 6:1–4). Chapter 5 turns this into a usable method for actual decisions.

The Commandments: Law as Gift

Given all this, what is the place of God’s commandments?

The Ten Commandments (Exodus 20:1–17; Deuteronomy 5:6–21) are given, significantly, after the rescue from Egypt, not before it. God does not say, "Keep these and I will free you.” He says, in effect, “I have freed you; this is how free people live.” Law follows grace in the Old Testament exactly as it does in the New.

Christian tradition has distinguished within the Old Testament between:

• moral law — permanent commands rooted in God’s character and human nature, such as the prohibitions of murder, theft, adultery, and false witness;
• ceremonial law — the regulations of sacrifice, priesthood, and ritual purity, fulfilled in Christ, who is Himself the sacrifice and the priest (Hebrews 9–10);
• civil or judicial law — the legal code of ancient Israel as a nation, including penalties suited to a particular society at a particular time.

This distinction is genuinely useful, and it explains why a Christian may eat shellfish but may not bear false witness. It must be applied carefully rather than as a convenient sorting device for keeping the commands we like — Chapter 5 and several later chapters discuss how to make the distinction responsibly and how to read the hardest passages of the Old Testament honestly rather than by embarrassed silence.

Christ intensified rather than relaxed the moral law. He said he had come not to abolish it but to fulfil it (Matthew 5:17) and then extended each command inward, from the act to the heart: not only murder but contempt; not only adultery but the lustful gaze (Matthew 5:21–30). This is decisive for everything that follows. Christian ethics is not satisfied with an unblemished record of external conduct. It is after the heart, because it is the heart that will be transfigured.

The Beatitudes: A Portrait Rather Than a Checklist

If the Commandments give the boundaries, the Beatitudes (Matthew 5:3–12) give the portrait. They describe the person who is being remade: poor in spirit, mourning, meek, hungry for righteousness, merciful, pure in heart, peacemaking, and — soberingly — persecuted.

Notice that these are not commands in the ordinary sense. Nobody can decide to be poor in spirit by an act of will before lunch. They describe a character that emerges. They also describe a life that the world does not reward, which is why the list ends where it does. Christian ethics is not a strategy for a comfortable life, and the Coptic Church, whose calendar begins with the Era of the Martyrs, has never had the luxury of pretending otherwise.

The Two Great Commandments

Asked to name the greatest commandment, Christ gave two and bound them together: love God with everything you are, and love your neighbour as yourself (Matthew 22:37–40). All the Law and the Prophets, He said, hang on these.

This is the interpretive key to the entire moral tradition. If a reading of a commandment leads you to something that is not love of God and not love of neighbour, you have misread it. St Augustine put it in a formula that has been quoted ever since and also frequently abused: 'Love, and do what you will.' [6] He was not licensing self-indulgence. He was making a rigorous claim: that genuine love — the love of God poured into a person by the Holy Spirit — will never desire what harms the beloved. The formula is safe only when “love” retains its full biblical weight. Emptied of that, it becomes exactly the modern sentimentality that this book resists.

Note too the phrase “as yourself". Scripture assumes a proper self-regard as the measure of neighbour-love. This has pastoral consequences. A Christian who despises himself, punishes himself, and finds his own existence contemptible is not thereby holier. Self-hatred is not humility; it is often pride turned inside out, and it makes a person less able to love others, not more.

The Holy Spirit: Why This Is Not About Willpower

Everything described so far would be crushing if it were a programme of self-improvement. It is not. St Paul lists the marks of a transformed life and calls them the fruit of the Spirit — “love, joy, peace, forbearance, kindness, goodness, faithfulness, gentleness and self-control” (Galatians 5:22–23, NIV). Fruit is grown, not manufactured. The gardener’s work is real and necessary, and it is not the same as the work of the life inside the seed.

Practically, this means that the Christian struggling with a habit is not simply someone who needs to try harder. Trying harder has its place, and so do sensible measures — accountability, removing occasions of temptation, and, where relevant, professional treatment. But the deepest movement is God’s: “it is God who works in you” (Philippians 2:13, NIV). This is why prayer, the sacraments, and the Church’s disciplines are not add-ons to Christian ethics. They are the means by which grace actually reaches a human life. A person trying to become chaste, honest, or sober by willpower alone, without prayer, without confession, without the Eucharist, and without community, is attempting to grow a tree in a cupboard.

The Church: A Moral Community and a Hospital

Modern ethics tends to imagine a lone individual deciding. Christian ethics assumes a community.

The Church forms us morally in ways we barely notice: through the words of the Liturgy, repeated until they become the furniture of the mind; through the calendar, which trains desire by alternating fasting and feasting; through the lives of the saints, which show what the commandments look like when they are wearing a body; and through the presence of people not of our choosing, which is where love of neighbour stops being theoretical.

The Church also heals. Confession is the central instrument here, and it is worth saying clearly what it is and is not in the Coptic tradition. It is not the humiliation of a sinner by a superior. It is the moment where a wound is brought into the light, before God, in the presence of a priest who has heard everything before and is not going to flinch. The priest is bound to absolute confidentiality. His task is absolution and treatment: not merely to declare forgiveness but to help the penitent understand the mechanism of the fall and to prescribe a path — a practice, a discipline, sometimes a period before receiving Communion, sometimes a referral to a doctor or counsellor.

And precisely because the Church is a hospital, it must be safe. A hospital that harms its patients has become the opposite of itself. Any account of Christian ethics written in this century that did not say plainly that the Church has sometimes been the place where the vulnerable were injured would be worthless. Chapter 22 and Chapter 42 address this directly, without evasion, because the honour of the Church is not defended by concealment. It is defended by repentance.

Freedom: What Christians Actually Mean

The modern world defines freedom as the absence of constraint: I am free to the extent that nothing prevents me from doing what I want.

The Christian tradition regards this as a shallow account, because it says nothing about the state of the wanting. Consider a man addicted to gambling. Nobody constrains him. He is, in the modern sense, perfectly free, and he is losing his house. Consider anyone who has ever done at midnight what they swore at noon they would not do. The obstacle to their freedom was not external.

Christ said that everyone who sins is a slave to sin and that the Son can make a person free indeed (John 8:34–36). Freedom, in this account, is not the absence of limits but the capacity to actually do the good you recognise. It is the condition of a person whose desires and judgement have been brought into agreement so that they are no longer at war with themselves. On this understanding the disciplines of the Church are not restrictions on freedom; they are its training. The pianist who has practised scales for ten years is more free at the keyboard than the person who has never practised, not less.

Why Love Does Not Mean Approving Everything

One conviction of our age must be met directly, because it stands behind a great many of the disagreements in this book: the belief that to love someone is to affirm their choices, and that to disapprove of a choice is to reject the person.

Christians should first admit the truth inside this belief. Disapproval has very often been delivered as rejection. When a family stops speaking to a child, when a parish gossips about a divorced woman, when a young person hears from the pulpit that people like them are disgusting, the message received is not “I love you and I think you are mistaken.” It is "You are not welcome here.” If that is what people mean when they say that disapproval is unloving, they have a case, and the Church must own its share of it.

But the identification of love with approval cannot be right, and no one lives as if it were. Parents disapprove of many things their children do, and their love is not thereby diminished but demonstrated. Friends who care about us tell us what we do not want to hear. A doctor who tells a patient the truth about their liver is not attacking them. In every close human relationship we distinguish between the person, who is loved unconditionally, and the action, which is assessed honestly.

What the Church owes every person is unconditional love, unfailing respect, protection from cruelty, a genuine welcome, and honesty. What it cannot offer is a revision of what it believes to be true in order to spare someone discomfort, because a church that adjusts its teaching to please is no longer of any use to anybody — including to the person being pleased, who came looking for God and was handed a mirror.

The difficulty, of course, is in the execution. It is easy to state the principle and hard to be the parish where it is actually experienced. Much of the second half of this book is an attempt to work out, situation by situation, what this looks like in practice.
