At first glance, the Old Testament teaching “an eye for an eye” appears harsh or even barbaric. Modern readers may even flinch when hearing this, thinking that it promotes revenge.
Many people often look upon these words as relics of an uncivilized past, a world where justice was crude and punishment was brutal. As Catholics who embrace Christ’s teaching, the idea of taking an eye for an eye appears out of place.
What Does it Really Mean?
This phrase appears three times in the Old Testament as Mosaic Law, in Exodus 21:23-25, Leviticus 24:19-20, and in Deuteronomy 19:21. But one should consider looking at this passage through the eyes of those living in 1500 BC.
In many ancient societies, if a man from one tribe injured a man from another, the offended tribe might retaliate by killing not just the offender, but his entire family or even the entire village. Violence escalated quickly, and justice often devolved into blood feuds.
Cultures that practiced this brutal vengeance surrounded the Hebrews in 1500 BC. But Mosaic Law changed this. Mosaic Law was God’s law that He gave to Moses and to the Hebrews. And God most certainly knew what He was doing when He gave the Hebrews these laws.
Scripture often challenges modern assumptions. The law does not intend this harsh language to promote violence and retaliation, but rather to teach restraint and offer reparation by those who initiate wrongdoing.
This law served as a limit, not a license. It restricted punishment to the level of the offense as opposed to a disproportionate retaliation. An eye for an eye, not both eyes for one eye.
An eye for an eye established the principle of measured justice. In other words, it was a moral brake on human anger.
Equality in ancient times was an unknown concept. The Pharoh’s eye was worth more than that of a Hebrew’s.
But the phrase “an eye for an eye” also has deeper meaning. It reveals a profound truth about justice, equality, and the dignity of every human person. It ensured that justice was not arbitrary, and it prevented the powerful from exploiting the weak. Every person – rich or poor, noble or common, slave or free – is equal before the law. The purpose is not cruelty but fairness.
Lessons from Non-Christian Cultures
This idea was revolutionary in the ancient world and remains so today. Anyone who has lived overseas in non‑Christian cultures quickly learns that equality is not universal. In many societies, caste, wealth, or political status determines a person’s worth rather than inherent dignity. These cultural structures reveal how radical the Mosaic Law truly was.
Consider India, where the caste system has shaped society for thousands of years. Even today, despite legal reforms, caste distinctions influence social interactions, marriage, employment, and justice. In such a system, the “eye” of a Brahmin (the highest caste) carries far more value than the “eye” of a Dalit (an untouchable). If a low caste man injures a higher caste man, the punishment may be severe. But reversing the situation often results in minimal consequences.
In this context, “an eye for an eye” would be revolutionary by declaring that the eye of a Dalit is worth exactly the same as the eye of a Brahmin.
As an interesting side note, a Dalit who escapes India and legally immigrates to the United States can become a U.S. citizen with the same rights under the law as any other U.S. citizen and even own a business. None of this is possible in India.
A similar dynamic exists in mainland China, where political status and wealth often determine the value of a person’s injury. A common laborer’s “eye” is worth little in the eyes of the courts. However, a wealthy businessman’s or party official’s eye is often treated as priceless. Compensation varies dramatically depending on one’s social standing.
Take the case of traffic accident causing a fatality. Authorities may throw a common man in prison while allowing the son of a rich businessman to buy his way out of trouble. Moreover, the son of a ranking political official … well you get the picture.
As the West becomes more secular and imports cultures that do not embrace Christian values, observers can clearly see a backslide in which social and political status wins favor. Authorities throw a lowly army private in prison for holding a top‑secret document while they never hold cabinet officials and other high‑ranking representatives accountable.
In such a secular world, the Mosaic Law stands as a bold contradiction. It asserts that justice must not be bought and the powerful cannot demand more than the weak. By God’s direction, justice must be fair and equal.
Honest Reparation, not Revenge
The phrase “eye for an eye” is not merely a literal command, but rather a principle of just reparation. When someone causes harm, one must make things right. The offender must repair the damage or restore what was taken.
In modern terms, if someone breaks a window in your home, he/she is legally responsible for the cost of the repair. If someone harms someone else’s property, the person doing the harm must restore it. That is not vengeance; that is responsibility.
Everyday life offers other examples. For instance, if a child accidentally breaks a classmate’s glasses, the parents of the child who broke the glasses replaces them. Or if break a tool I borrowed from you, I should replace it.
These practices reflect the same principle found in Mosaic Law. Justice requires restitution. Justice requires acknowledging the harm and repairing it.
Rooted in Genesis
The deepest foundation of this law lies in the opening chapters of Genesis. Genesis 1:27 reads, “God created mankind in his image; in the image of God he created them; male and female he created them.” In other words, God created all humans in His own image – as equals.
If every person bears God’s image, then every person possesses equal dignity. This dignity does not depend on wealth, status, race, age, or occupation. It does not depend on political power or social influence. It does not depend on intelligence, beauty, or success.
This means a billionaire and a teenager working part‑time at a grocery store share the same dignity. A politician and a constituent stand equal before God. A person with dark skin and a person with light skin reflect the same divine image. An unborn child in the womb has just as much dignity as the blue-haired, third wave feminist who wants the child aborted (and we should pray for them both).
This truth forms the bedrock of Christian morality. It explains why “an eye for an eye” is fundamentally about equality.
Christ’s Reference
In Matthew 5:38-39, Christ references Mosaic law, “You have heard that it was said, ‘An eye for an eye and a tooth for a tooth.’ But I say to you, offer no resistance to one who is evil. When someone strikes you on [your] right cheek, turn the other one to him as well.” This passage is also fundamentally about equality.
At the time of Christ, striking someone on the right cheek meant using the back of the right hand. This was not a punch in the face, but rather an insult meant to demean someone as inferior. This is where the term ‘back-handed insult’ originates.
By offering the left cheek, the recipient bates the aggressor to strike again with the palm, an action reserved for equals. By turning the other cheek, the person is forcing the attacker to treat them as an equal rather than an inferior.
Far from being harsh, the teaching of “an eye for an eye” reveals God’s justice rooted in the inherent dignity of each human. It reminds the world that no one stands above another in worth proclaiming that every person deserves equal respect regardless of wealth, status, skin color, ethnicity, or age. “An eye for eye” does not blind the world. It helps it see straight.
