"Be perfect, therefore, as your heavenly Father is perfect."
— Matthew 5:48
If you sit in the average church, you will often hear this verse taught as a setup for grace. The pastor might say, "God demands perfection. You cannot achieve it. Therefore, you need Jesus to save you." Or you might hear it taught as a distant goal: "We strive for perfection, but we will only reach it in the afterlife."
Both teachings share a common assumption: "perfect" means "flawless, sinless, and without a single defect."
But what if that assumption is wrong? What if the English word "perfect" has played a trick on us? To understand what Jesus actually commanded, we need to look at the facts of history, language, and translation.
What did "perfect" mean in the 16th century?
When the Bible was first translated into English in the 1500s, the word "perfect" (often spelled perfit or perfecte) did not mean "zero defects." Its primary meaning was "complete, finished, fully realized, or lacking nothing essential."
This came from the Latin word perfectus, which simply meant "to finish" or "to complete." The main idea was wholeness and reaching a goal.
We still see this older meaning in a few specialized areas of modern English:
- Law: When lawyers finalize a legal agreement, they say they have "perfected the contract." They don't mean the contract is flawless; they mean it is legally complete.
- Grammar: The "perfect tense" (like I have eaten) describes an action that is fully completed, not an action done without mistakes.
- Everyday Idioms: If you meet a "perfect stranger," you mean they are a complete stranger. If you have a "perfect right" to be angry, you mean you have a full and total right.
In the 16th century, when applied to a person's character, "perfect" meant fully developed in goodness, mature, and whole. It described spiritual integrity, not an impossible, sinless flawlessness.
The Greek Word Behind the Command
To know exactly what Jesus meant, we must look at the original Greek text of Matthew 5:48. The Greek word used is τέλειος (teleios).
Teleios comes from the root word telos, which means "end, goal, or purpose." Therefore, teleios means "having reached its goal; complete; full-grown; mature."
Context is everything. In Matthew 5, Jesus is teaching his followers to love their enemies. He points out that God sends rain and sunshine on both good and bad people. God's love is complete, undivided, and impartial. Jesus is telling his followers: Your love must be complete and undivided, just like God's love.
He is not demanding a static state of sinless perfection. He is calling for a dynamic, mature, and complete love.
How "Perfect" Became a Problem
The Greek teleios was translated into Latin as perfectus, which meant "complete" or "finished." That Latin word passed into English as "perfect" — still carrying the same meaning of wholeness, not flawlessness. Every major English translation from Wycliffe to Tyndale to the King James maintained this sense.
So, when did the meaning change? The English language shifted underneath the Bible translation.
- In the 16th and 17th centuries, "perfect" meant complete and fully developed.
- In the 18th century, the Enlightenment brought new ideals of science and art. "Perfect" started to mean "ideal" and "flawless."
- By the 19th century, the older meaning of "complete" faded away. For everyday speakers, "perfect" came to mean "utterly without defect."
Have Modern Bibles Fixed This?
Today, Bible translators face a difficult choice. Do they keep the famous word "perfect," or do they change it to fix the modern misunderstanding?
Translations that keep "perfect": Most major modern Bibles (ESV, NIV, NRSV, NASB) keep the word "perfect." However, they recognize the problem. They usually add a footnote explaining that the Greek means "complete, whole, or mature."
Translations that change the wording: Some modern translations choose to bypass the word "perfect" entirely to give the reader the correct Greek meaning immediately:
- Common English Bible (CEB): "Therefore, just as your heavenly Father is complete in showing love to everyone, so also you must be complete."
- New English Bible (NEB): "There must be no limit to your goodness, as your heavenly Father's goodness knows no bounds."
- The Message (Paraphrase): "In a word, what I'm saying is, Grow up. You're kingdom subjects. Now live like it."
The debate continues among scholars: is it better to keep the traditional word and hope people teach its true meaning, or update the text to prevent confusion and force teachers to adapt?
The Danger of the Modern Misunderstanding
When we read "perfect" through the modern lens of "sinless flawlessness," we distort Jesus' teaching in four major ways:
1. It turns an attainable goal into an impossible ideal. The Greek teleios describes a mature person whose love is fully realized. This is an achievable goal of character. But the modern word "perfect" implies a zero-defect condition. Because no human can achieve zero defects, we mentally file the command under "impossible" and give up.
2. It disconnects the verse from love. Matthew 5:48 is the conclusion of a paragraph about loving your enemies. The point is to have a complete, non-selective love. When we hear "perfect" as general flawlessness, we forget about love. We think Jesus is demanding perfect rule-following instead of wholehearted love.
3. It pushes the command into the afterlife. If I cannot be flawless in this life, I will just wait until I die. This creates a passive view of salvation. We think, "I am a sinner, I can't be perfect now, so Jesus must be talking about heaven." This destroys the urgent, present-tense call to action in the Sermon on the Mount. Jesus wants us to live this way now.
4. It ignores the Jewish wisdom tradition. Jesus was a Jewish rabbi speaking to a Jewish audience. The Hebrew equivalent to teleios is tamim (תָּמִים). In the Old Testament, Abraham, Noah, Job, and David are each called tamim. It means blameless, wholehearted, or having integrity. It does not mean sinless. Translating it as the modern "perfect" replaces rich biblical spirituality with cold, Greek philosophical idealism.
The Big Picture: Wholeness Over Flawlessness
When we define "perfect" as "sinless," it is very easy to put Jesus on a pedestal. We separate him from us, saying, "He was sinless, and I am sinful." Christian teaching is reduced to a focus on the distinctiveness of the two.
But that is not what Jesus was teaching.
The biblical concept of tamim (wholeness) proves a beautiful truth: A person can be wholehearted and still make mistakes. Having integrity does not mean you never fail; it means your heart is fully directed toward God. When a tamim person sins, they do not hide. They repent, and repentance restores their relationship with God.
"Being perfect" is not about being a flawless robot. It is about being completely, wholly, and maturely devoted to loving God and loving your enemies today. It is a demanding call, but it is a genuinely possible one.
Stop trying to be flawless. Start trying to be complete.
