Fletcher's Six Propositions (or "Six Fundamental Principles") are axioms that follow from making agape the centre of ethics. They explain how love should function in moral decision-making and show what it means for love to be the only absolute. The propositions are: (1) Only love is intrinsically good—nothing else; (2) Love is the only ruling norm for Christian ethics; (3) Love and justice are the same thing—"justice is love distributed"; (4) Love wills the neighbour's good whether we like them or not; (5) Only the end justifies the means—if the outcome is the most loving, the action is justified; (6)Love's decisions are made situationally, not prescriptively—no fixed rules, just respond to each unique situation with love. Together, these propositions show that agape is the only absolute—everything else (rules, laws, principles) is relative to love and can be broken if love requires it.
The Six Propositions are axioms that follow from making agape the centre of ethics. They explain how love should function in moral decision-making and show what it means for love to be the only absolute in ethics.
"Only one thing is intrinsically good; namely, love: nothing else at all."
Because love is the only intrinsic good, actions like lying, stealing, or even killing have no inherent moral status. They only become good or evil depending on whether they serve love.
"The ruling norm of Christian decision is love: nothing else."
Jesus said the greatest commandment is: "Love the Lord your God... and love your neighbour as yourself" (Matthew 22:37-39). Fletcher interprets this to mean: all other rules exist only to serve love.
"The situationist follows a moral law or violates it according to love's need."
By "love," Fletcher means agape—"good will at work in partnership with reason". It's an attitude, not a feeling or desire.
"Love and justice are the same, for justice is love distributed, nothing else."
The agapeic calculus: aim for "the greatest amount of neighbour welfare for the largest number of neighbours possible". This is like utilitarianism's "greatest happiness"—but with love instead of happiness.
"Love wills the neighbour's good whether we like him or not."
Even towards enemies, agape insists: "however we rate them, and whether we like them or not, they are our neighbours and are to be loved."
"Only the end justifies the means, nothing else."
When evaluating a situation, consider:
This means any action can potentially be justified if it produces the most love. Fletcher gives extreme examples: killing a baby to save a family, abortion, euthanasia.
"Love's decisions are made situationally, not prescriptively."
A woman in Arizona learned she might bear a baby with severe defects because she had taken thalidomide. What should she do? The law said all abortions are wrong. But Fletcher says: the loving decision was not given by the law—it must be decided situationally.
The Flow:
The Six Propositions provide a clear, unified framework for ethics. One principle (love) guides all decisions.
By making decisions situationally, the theory can respond to complex, unique situations. No rigid rules that fail in edge cases.
Jesus explicitly said love is the greatest commandment. Fletcher builds directly on this biblical foundation.
Personalism ensures people come before rules. Rules exist to serve human welfare; when theydon't, they should be broken.
Proposition 5 allows terrible actions to be justified if the outcome is "loving". Murder, torture, lying could all be justified. This is the classic problem with consequentialism.
Who decides what the "most loving" outcome is? Different people may interpret love differently. This can lead to moral relativism.
We often can't know what the most loving outcome will be. Our predictions about consequences are often wrong. How can we base ethics on unpredictable outcomes?
William Lane Craig argues Fletcher has "diluted Christian ethics into just loving and wanting the best for others". Christianity has more to say about ethics—justice, holiness, obedience matter too.
"Only one thing is intrinsically good; namely, love: nothing else at all. The ruling norm of Christian decision is love: nothing else. Love and justice are the same, for justice is love distributed, nothing else. Love wills the neighbour's good whether we like him or not. Only the end justifies the means, nothing else. Love's decisions are made situationally, not prescriptively."

Context: Fletcher's complete statement of the Six Propositions—the fundamental principles showing how agape functions as the sole basis for moral decision-making.
"Any action we take, as considered as an action independent of its consequences, is literally 'meaningless and pointless'. An action, such as telling the truth, only acquires its status as a means by virtue of an end beyond itself. The end must be the most loving result—so anything done to try and achieve that end goal is justified."
— Joseph Fletcher, Situation Ethics (1966), on the Fifth Proposition
Context: Fletcher's consequentialism explained—actions have no inherent moral status; they're only good or bad depending on whether they produce the most loving outcome.
| # | Proposition | Key Point |
|---|---|---|
| 1 | Only love is intrinsically good | Nothing else is good in itself; actions are good/evil based on whether they serve love |
| 2 | Love is the ruling norm | Love replaces all other laws as the basis for ethics |
| 3 | Love and justice are the same | "Justice is love distributed"—to act justly is to act lovingly |
| 4 | Love wills the neighbour's good | Extends to everyone, even those we don't like or who are enemies |
| 5 | Only the end justifies the means | Consequentialism—outcomes determine morality |
| 6 | Love decides situationally | No fixed rules; respond to each unique situation with love |
Six Propositions: axioms explaining how agape functions in ethics
Proposition 1: Only love is intrinsically good—nothing else
Proposition 2: Love is the only ruling norm for Christian decision-making
Proposition 3: Love = justice; "justice is love distributed"
Proposition 4: Love wills the neighbour's good whether we like them or not
Proposition 5: Only the end justifies the means—consequentialism
Proposition 6: Decisions made situationally, not prescriptively—no fixed rules
Agapeic calculus: greatest love for greatest number of neighbours
Love is the only absolute; everything else is relative to love
Strength: simple, flexible, grounded in Jesus' teaching, puts people first
Criticism: "end justifies means" is dangerous; subjective; can't predict consequences
William Lane Craig: reduces Christianity to general well-wishing, ignores holiness and justice
