Mere Christianity

1.Lewis uses the image of a hallway leading into separate rooms to describe 'mere Christianity.' What is the hall, and what are the rooms? Why does he think it matters to get people into the hall before worrying about which room they enter?

2.He deliberately avoids advocating for any particular denomination. Do you find this approach reassuring or frustrating? What might be gained — and lost — by focusing only on what all Christians share?

1.Lewis begins with the observation that when people quarrel, they appeal to a standard they both assume the other person knows — 'That's not fair,' 'You promised.' What is he trying to show with this simple, everyday observation?

2.He distinguishes between the Law of Nature (how things like trees and gravity *do* behave) and the Law of Human Nature (how humans *ought* to behave but often don't). Why is this distinction crucial to his argument?

1.The first objection Lewis takes up is that the Moral Law is just herd instinct. How does he distinguish between a moral impulse and a moral law? What is the analogy he uses about two different impulses (such as helping someone in danger vs. self-preservation)?

2.Lewis argues that the Moral Law is not itself an instinct but the thing that *adjudicates* between instincts. Does this distinction make sense to you? Can you think of a personal example where two instincts conflicted and something else decided which one to follow?

1.Lewis argues that the Moral Law is not simply a description of how humans behave but a *prescription* of how they ought to. What is the difference, and why does it matter for his argument about God?

2.He says the Moral Law is the one thing in the universe that cannot be dismissed as 'just the way things happen to be.' Why can't we be comfortable with that explanation for morality when we can be comfortable with it for, say, gravity?

1.Lewis presents two broad views of the universe: the Materialist view (matter and energy, nothing more) and the Religious view (something behind the facts). In your own words, what is the essential difference between these two positions?

2.He also distinguishes between the Life-Force philosophy (a creative energy driving things forward) and full-blown Theism (a Mind behind the universe). What is the difference, and why does Lewis think the Life-Force view is ultimately unstable?

1.Lewis says he has been 'putting the boot in' — deliberately making the reader feel the weight of the Moral Law's condemnation before offering any relief. Why does he think this sequence matters? What is wrong with offering comfort too soon?

2.He uses the analogy of a man in trouble with the police: Christianity doesn't make sense as 'good news' until you first understand the bad news. How has your own experience of the gospel been shaped — helped or hindered — by how clearly you've understood the 'bad news'?

1.Lewis opens Book II by distinguishing between Pantheism (God is everything, or the sum of reality) and Theism (God made the world and is distinct from it). What are the practical differences between these two views for how we think about good and evil?

2.Lewis introduces his famous argument from atheism: as an atheist, he had felt the universe was 'unjust' — but this very sense of injustice presupposes a standard of justice that transcends the universe. How does his own story illustrate the self-defeating nature of certain kinds of atheism?

1.Lewis describes the Christian story as 'enemy-occupied territory.' What does this metaphor capture about the human condition and about God's response to it? What might be lost with a gentler metaphor?

2.He says Christianity involves the claim that the rightful King has landed in disguise, calling all people to join a great campaign of sabotage. How does this framing change the way you think about the Incarnation and about the Christian life?

1.Lewis presents the famous 'Liar, Lunatic, or Lord' trilemma. What is the argument, and what is it designed to rule out? In your own words, why does Lewis think the 'just a great moral teacher' option is not available?

2.He says that a man who said the things Jesus said would either be God, or a lunatic on the level of someone who claimed to be a poached egg. This is deliberately extreme language. Why does Lewis use such extreme language — is it fair or is it overstated?

1.Lewis frames the problem this way: a man who is in debt cannot pay what he doesn't have; a man who has wronged God cannot give back what he's taken. He needs help from outside. How does this frame the need for the Atonement differently from simply 'needing forgiveness'?

2.Lewis introduces the idea that repentance requires dying to self — a kind of surrender and humiliation — and that this is so hard it requires the power of God to accomplish. He says we 'need God to do for us what we cannot do for ourselves.' What does this say about the relationship between the Incarnation and Atonement?

1.Lewis describes three ways Christ's 'good infection' (as he calls it) is passed on: through baptism, belief, and the Lord's Supper. He doesn't ask us to fully understand *how* these work, but to use them. What is the analogy he draws to eating food without understanding nutrition? Do you find this analogical approach helpful?

2.He introduces the concept of 'pretending' — acting as if you are a Christian before you fully feel like one, and finding that the pretense gradually becomes reality. This sounds like it could be hypocrisy. How does Lewis distinguish healthy pretense from hypocrisy?

1.Lewis uses the fleet-of-ships analogy to describe the three departments of morality: relations between ships, the internal workings of each ship, and the purpose of the whole fleet. What are the three corresponding dimensions of human morality?

2.He argues that modern people tend to think of morality almost exclusively as relations between individuals — fairness, kindness, honesty. The other two departments (internal character and ultimate purpose) are neglected. Do you recognize this narrowing in your own culture or community? In yourself?

1.The four Cardinal Virtues are Prudence, Temperance, Justice, and Fortitude. Lewis says they are 'cardinal' because everything else hinges on them ('cardo' means hinge). Before reading further in the chapter, can you define each one? How do your definitions compare to Lewis's?

2.Lewis is particularly concerned to rescue the word 'Prudence' from the sense of timidity or caution. He says Prudence is practical wisdom — the ability to think clearly and act sensibly. Why does he insist that God is not opposed to clear thinking, and why might Christians sometimes act as if He is?

1.Lewis states that the New Testament gives almost no direct political program, and he is deliberately reticent about translating Christianity into specific policy. Why does he take this position? Do you agree with his restraint, or do you think Christianity has more specific social implications than he allows?

2.He invokes the 'rule of thumb' that every penny more than the minimum necessary is taken from the pockets of the poor. This is a striking economic claim. What is Lewis driving at, and how does it challenge comfortable middle-class Christianity?

1.Lewis argues that psychoanalysis and Christianity are not rivals but operate on different levels. Psychoanalysis deals with the material of our instincts and complexes; Christianity deals with what we *do* with that material. What is the distinction he is drawing, and why is it important?

2.He makes a crucial point about moral responsibility: two people with different psychological starting points cannot be compared simply by their actions. A person who overcomes a powerful temptation may show more virtue than someone who is not tempted at all. How does this challenge common judgmentalism?

1.Lewis uses the analogy of an audience that goes wild watching a strip-tease act with food to introduce his argument about the state of sexual appetite in modern culture. What is he suggesting about the relationship between the appetite and the culture that feeds it?

2.He distinguishes between the Christian standard for sexuality (chastity) and the idea that sex itself is shameful or wrong — a distinction he says Christianity has never held. Why is this distinction important, and how does it reframe chastity as a positive rather than negative virtue?

1.Lewis distinguishes between 'being in love' (a feeling that comes and goes) and the commitment of marriage. What does he say about the relationship between the two, and why is this important for understanding the Christian view of marriage?

2.He argues that 'ceasing to be in love' does not mean a marriage has failed — the feeling was designed to ignite the will to commitment, not to replace it. How does this change the way we should understand the claim 'I fell out of love'?

1.Lewis begins by saying forgiveness sounds fine in the abstract until you actually have someone to forgive — a neighbor who has wrecked your life, a nation that has done monstrous things. How does his opening move the discussion out of the theoretical and into the real?

2.He unpacks the commandment 'love your neighbor as yourself' and points out that we actually do bear a kind of love for ourselves even while knowing our own flaws. We hate our own sins but still wish good for ourselves. What does this suggest about what forgiving others actually requires?

1.Lewis identifies Pride as the great sin — the root of every other vice. He says it is essentially competitive: we are not proud of having something so much as proud of having *more* of it than the next person. Do you find this competitive dimension in your own experience of pride?

2.He makes the strong claim that Pride is the one vice that no one in the world is free of, and it is the one vice that makes us incapable of knowing God. How does Pride specifically get between us and God — and between us and other people?

1.Lewis insists that 'charity' in the Christian sense means love — not just generosity with money. He says Love (in the sense of willing the good of another) is a virtue, not a feeling, and therefore it can be commanded. Why does it matter whether love is primarily a feeling or a choice?

2.He gives the practical advice: do not waste time wondering whether you 'love' your neighbor; act as if you do, and the feeling may follow. How does this connect to the 'pretending' argument from Book II, Chapter 5?

1.Lewis says that hope — longing for the eternal world — is not a form of escapism but one of the things a Christian is meant to do. He argues that people who have contributed most to the world have been precisely those who were most focused on the next. Who are the examples he has in mind, and do you find this claim persuasive?

2.He describes the experience of longing — a sense that nothing in this world ever fully satisfies — and says this is the clue that we were made for another world. Has this longing been part of your experience? What do you do with it?

1.Lewis defines Faith (in a first sense) as the art of holding on to things your reason has once accepted, in spite of your changing moods. Why does he say this takes courage, and what does it suggest about the relationship between faith and emotion?

2.He draws an analogy to other areas of life: we know logically that anesthesia is safe, but as the mask comes down we feel fear anyway. We know our reason told us something was true, but feelings tell a different story. How does this validate the experience of doubt without endorsing it as final?

1.Lewis distinguishes between faith as intellectual assent and faith as the total self-surrender he describes here. Why does he say that the virtuous pagan (someone who works very hard at being good) may actually be further from salvation than someone who knows they cannot manage it at all?

2.He describes the experience of coming to the end of your moral effort — realizing that trying your hardest has still left you far short. What does Lewis say this moment of moral bankruptcy is actually *for*?

1.Lewis distinguishes between 'making' and 'begetting.' A man makes a statue; he begets a child. The statue is made of different stuff; the child is of the same kind as the father. How does this distinction apply to the relationship between God and human beings — and to the relationship between God the Father and God the Son?

2.He introduces the terms 'Bios' (natural life) and 'Zoe' (spiritual life) — borrowed from Greek. What is the difference, and why does the whole of *Mere Christianity* ultimately hinge on the difference between these two kinds of life?

1.Lewis argues that prayer is the place where we discover the Trinity in practice — we speak to the Father, through the Son, with the Spirit. How does his description of prayer as being caught up into a divine exchange between Father, Son, and Spirit make prayer feel different from one-way communication?

2.He uses the analogy of dimensions: in one dimension you have a line, in two dimensions a square, in three dimensions a cube. He says moving from individual persons to the Trinity is like moving into a higher dimension — it does not cancel what we know, it includes it. Do you find this analogy illuminating or frustrating?

1.Lewis argues that God does not experience time the way we do — he does not live in a 'succession of moments' but sees all moments simultaneously, as we see a landscape spread out before us. How does this resolve the apparent problem of God 'foreknowing' our free choices?

2.He addresses the question: if God already knows what will happen, does prayer change anything? How does Lewis's account of divine timelessness reframe the question?

1.Lewis revisits the idea of the Son of God as the source of Zoe — the divine life — and argues that through Christ this life is 'catching.' What does the infection metaphor capture that a more formal theological explanation might miss?

2.He argues that the relationship of love between Father and Son is eternally self-generating — the Son is not a 'result' of the Father in the way a child results from parents. What does this suggest about the nature of love within the Trinity, and why does it matter for how we understand grace?

1.In 'The Obstinate Toy Soldiers,' Lewis describes the Incarnation as God becoming a wooden soldier in order to turn wooden soldiers into real people. What does this earthy image capture that more technical atonement language might obscure?

2.In 'Let's Pretend,' Lewis returns to the 'pretending' theme: saying the Lord's Prayer ('Our Father') when you barely believe it is a form of pretending — but a pretending God uses. What is the difference between this and hypocrisy, and how does this chapter deepen what he said in Book II?

1.At the beginning of the guide you were asked to write down your biggest question or area of doubt about Christianity. Pull that out now. Has it been answered, deepened, or replaced by a different question? What has the journey through this book done with it?

2.Which single chapter or argument from *Mere Christianity* has been most impactful for you — and why? Was it an intellectual breakthrough, an emotional resonance, or a conviction about how you need to live differently?
