WWJD: How Did Jesus Act? (Jesus as a Moral Teacher)
What did Jesus believe about ethics? Which of the great philosophers would He have agreed with? J.P. Moreland delves into the two ethical theories that he believes Jesus subscribed to.
Jesus' Ethics
It has long been recognized that, irrespective of one's religious views about Jesus of Nazareth, He is one of the world's leading ethical thinkers and teachers. Indeed, as late as the second world war, most moral thinkers in the West — secular or not — did their best to show that their moral theories yielded results in keeping with the ethics of Jesus.
In my previous article, "How Did Jesus Argue?", we saw that Jesus was a logical thinker even though He did not expressly teach a particular version of logic (syllogistic logic, sentential logic, first-order logic).
In the same way, while Jesus was an ethical teacher, He did not lay out explicitly a moral system like Aristotle did in the Nicomachean Ethics or John Rawls in A Theory of Justice. Still, it is possible and desirable to see if there is an implicit system in Jesus' view of the moral life. Possible because like any good thinker, Jesus' ideas about the moral life are internally consistent and rooted in an underlying view of the nature of moral life itself. Desirable because an understanding of Jesus' moral system could help to shed light on how Jesus might approach certain moral situations He did not explicitly address.
Before we get into certain territory that may be unfamiliar to readers, let's quickly identify three aspects of Jesus' moral views.
First, He was an objectivist and not a relativist: Jesus believed that correct moral principles are objectively true irrespective of whether or not anyone believes them. Jesus took certain moral rules to be binding on people whether or not they accepted those rules. This is clear in many ways, including His stance as a moral reformer and critic of His culture. He took some of the Pharisees' legalistic teachings to be wrong even though the Pharisees believed them, and He held people responsible for moral rules they did not accept (e.g., for caring for people in other ethnic groups than one's own as seen in the parable of the Good Samaritan).
Second, He believed that there was such a thing as moral knowledge: We are not left to simply believe blindly in the correctness of certain moral truths; we can actually know they are true and are, thus, responsible to follow them. Jesus did not try to prove fundamental moral precepts — e.g., the Golden Rule. He assumed people already knew many of them. Rather, He tried to reduce people's resistance to them and sought to move people to act on them.
Third, He believed the moral law comes from God Himself and is rooted in His loving, holy, righteous nature. This much is clear and fairly uncontroversial. Still, in a day when moral confusion abounds, it is worth reminding ourselves of these initial features of Jesus' understanding of morality.
This brings us to the two central insights about Jesus' moral teaching that I want to identify more thoroughly: Jesus was a deontologist and He was also a virtue ethicist. Let me explain.
Deontological Ethics
The word "deontological" comes from the Greek word "deon" which means "binding duty." In the history of philosophy, Immanuel Kant is perhaps the most famous advocate of a deontological system of ethics. Roughly, deontological ethics focuses on right and wrong moral actions and moral rules and holds that some moral acts and rules are intrinsically right or wrong, irrespective of the consequences produced by doing those acts or following those rules.
According to deontological ethics, morality is its own point, at least in part, and moral duty should be done for its own sake.1 Standing in sharp contrast to utilitarian systems (according to which the rightness or wrongness of a moral act or moral rule (e.g., "Keep your promises") resides entirely in the net amount of good vs. bad consequences produced by that act or by following that rule compared to alternative acts or rules), deontological ethics centers around the following theses:
- Moral duty should be done for its own sake. Some moral rules are intrinsically right (e.g., "one ought to love one's neighbor") and should be done for that reason.
- Persons have intrinsic value and are ends in themselves. They should not be treated as a mere means to some other end; they do not simply have instrumental value.
- A moral rule is universalizable in the sense that it is equally binding on all people at all times in relevantly similar situations. Among other things, this principle expresses rational consistency — namely, that one ought to be rationally consistent about one's moral judgments. If act X is judged right for person P, then X is right for anyone relevantly similar to P.
The classic example of deontological ethics are the ten commandments — they should be followed by all people in all situations. And Jesus taught moral principles in such a way as to understand them as intrinsically correct, universally binding and including a view of human beings as objects of intrinsic value in the image of God.
As mentioned above, "Love your neighbor as yourself" is a good example of a deontologically conceived moral principle. Also, at the beginning of His public ministry, Jesus affirmed His commitment to the Mosaic Law which is predominantly written in the form of rules and precepts (Matthew 5:17). And near the end of His public ministry, Jesus affirmed that one should obey the moral rules in the Law including its lesser requirements (Matthew 23:23). In these and related ways, Jesus affirmed the importance of moral rules and moral duty.
Virtue Ethics
By contrast to deontological ethics, virtue ethics focuses on the nature and formation of a good person, and the sort of dispositions and character traits that constitute the good person. According to virtue ethics, the good person is the one who is functioning properly, that is, as a human ought to function and, thus, is one who is skilled at life.
Virtue ethics, also called aretaic ethics (from the Greek word "aretë" which means "virtue") has a long and distinguished pedigree, going back to Aristotle and Plato, running through Thomas Aquinas, and including many contemporary advocates. Virtue ethicists sometimes claim that deontological ethics fails because it abstracts from the moral agent himself; it focuses entirely on doing the right things instead of on being a good person; and it provides little guidance for understanding how to develop ethical character and moral motivation.
Central to virtue ethics is the question of what a good person is and how a good person is developed. Further, the claim is made that deontological ethics places too much emphasis on moral autonomy whereas virtue theory includes an emphasis on community and relationships.
Virtue ethics is teleological (analyzing something for the purpose or end it serves) in nature. The sort of teleology involved in virtue ethics is not like that of utilitarianism. Utilitarianism is teleological in the sense that it focuses on what sort of action will maximize the greatest amount of good vs. bad consequences that follow from such an action.
By contrast, virtue ethics does not focus on actions and the consequences they produce. Rather, virtue ethics focuses on the overall purpose of life, namely to live well and achieve excellence and skill as a human person. In this sense, virtue ethics is deeply connected to a holistic vision of life and of the ideal human person. Given an understanding of ideal human flourishing and skillful living, an ethics of virtue is an attempt to clarify the nature of a good person and how to become one. Put differently, virtue ethics aims at defining and developing the good person and the good life, and virtues are those character traits that enable people to achieve eudaimonia, or happiness — not understood as a state of pleasurable satisfaction, but rather as a state of well-being, of excellence and skill at life.
The Sermon on the Mount seems clearly to be a treatise on virtue ethics, concerned as it is with characterizing the good person with an inner heart and character that reflects the Kingdom of God and the nature of the biblical God. Indeed, near its beginning, Jesus focuses on forming a heart that sets aside anger and a judgmental spirit (Matthew 5:21-26). He identified the inner recesses of the heart (and not merely the external adherence to moral rules) as the fount of the moral and spiritual life (Mark 7:17-23).
In Matthew 18:21-35, Peter asks Jesus how many times one needs to forgive one's neighbor. In Jewish culture at that time forgiving someone three times for the same offense was considered generous, so Peter goes beyond that and suggests the extreme notion of seven times. Jesus responds by saying that one needs to forgive 490 times! Clearly, Jesus did not mean that you are free not to forgive the 491st offense. What, then, did He mean by this outrageous number? Simply this: The topic of forgiveness is not adequately approached by thinking of it as duty to be performed a certain number of times. No, the key is to become a certain type of person — one who loves to forgive and has a heart ready and eager to do so. This is classic virtue ethics.
While deontological ethics places the analysis of correct/incorrect moral acts and rules in the most important spot, virtue ethics prioritizes the analysis of the good person and good character.
Criticisms
As I mentioned above, some have criticized deontological ethics for being cold and calculating. Why? Because it focuses on actions and rules in abstraction from the moral agents who perform those actions. Deontological ethics exclusively focuses on right action and correct rules. It leaves out the person entirely and has no concern for defining a good person, clarifying the difference between a good and bad character, and developing guidance for how to develop good character. This is precisely what virtue ethics provides.
But virtue ethics has been criticized because, allegedly, it fails to provide specific guidance in specific moral situations. Simply telling someone to become a wise, kind, honest person does not give him or her enough content to know exactly what principles such a person would follow. And deontological ethics provides precisely such guidance.
Virtues and Rules Can Coexist
Fortunately, one does not need to choose between the two, as some have claimed. Some ethicists hold, correctly in my view, that virtues and moral rules should coexist in some way. They claim that virtues without rules are blind, but rules without virtues are motivationally impotent. Both virtue and deontological ethics are necessary for an adequate moral system.
Neither virtues nor moral rules is basic; rather, each has intrinsic value and they complement each other. People have a duty to be a certain kind of person and to obey correct moral rules. The virtues refer to the traits that should characterize a good person and moral rules provide guidance for defining right and wrong moral actions. Thus, each has a different focus — virtues focus on the agent, and rules focus on the action. A comprehensive moral theory will include basic elements of each.
Do you think you're more concerned with following rules or having good character?
Join the discussion!
I have tried to show that this synthesis is exactly what Jesus accomplished. He was a deontological and virtue ethicist. As such, He was concerned with right action and objective moral rules, as well as with clarifying the nature of character, the good person, and the path to becoming one.

- Moral rules should also be followed because that makes one happy, it produces good consequences, and so forth. But the fundamental reason for acting morally on a deontological view is that it is right to do so. Back^
