Luke New Testament Greek

Context

Jesus is speaking to his disciples about the weight of causing others to stumble. He says it is impossible to avoid stumbling blocks, but warns those who place them. Then he turns to the way his followers should handle sin within the community. A brother sins against you. Jesus gives two actions: rebuke him; if he repents, forgive him. The verse sits in a series of teachings that lead the apostles to cry out for more faith. They sensed how hard this command truly is.

Key Words

The opening word, prosechō, means to watch out or pay close attention. It is the same word used when God tells Moses at the burning bush to take heed. Jesus is not giving a casual suggestion. He wants us alert to our own reactions and to the needs of our brother.

The word for rebuke, epitimaō, originally meant to assign worth or to honor. But in the New Testament it carries the sense of confronting someone with their fault. It is a corrective word, not a destructive one. You speak the hard truth because you care about the person, not because you want to wound.

Forgiveness here is aphiēmi, to let go, to release, to send away. It pictures untying a debt and letting the other person go free. And repentance, metanoeō, is a change of mind that turns the whole direction of a life. These are not small things. Rebuke opens the door, repentance prepares the heart, and forgiveness sets both people free.

How Christians Read This Verse

Most Protestant commentators emphasize that rebuke is a step toward forgiveness, not a way to keep a record of wrongs. Barnes notes that the rebuke seeks an explanation and gives the brother a chance to own his error. The Cambridge Bible for Schools says the rebuke is "only intended as a help" to the forgiveness that follows.

In Catholic teaching, the verse is often read within the larger framework of the sacrament of penance, where confession and repentance precede absolution. The Douay translation uses the phrase "do penance" for repentance, reflecting a sacramental understanding. Both traditions see the goal as restoration, not punishment.

A common misunderstanding

Some read this verse as a condition: you only forgive if the other person repents. If they don't, you are free to hold on to your anger. In fact, Jesus is describing the path to reconciliation in the community. The call to forgive from the heart remains constant (Matthew 18:21-35). But when a brother has sinned against you, you are not to pretend it never happened. You speak to him, and if he turns, you offer the full gift of forgiveness that you have already received from God.

Living This Out

This week, think of someone who has hurt you. Maybe it was a friend who spoke behind your back, or a family member who let you down. Before you nurse that wound, see if there is a way to gently speak the truth. A quiet conversation, not an accusation but an honest sharing of how their actions affected you. If they listen and say they are sorry, let it go. Release the debt fully. If they do not repent, you still release your bitterness to God in prayer. But this verse calls you to take the first step toward healing, not to wait for the other person to come to you.

Main takeaway: Jesus calls you to lovingly confront a brother's sin and to extend full forgiveness when he repents, trusting that both actions flow from grace.

For Families

For ages 5, 8

If your brother or friend takes your toy, you tell them it is wrong. When they say sorry, you say I forgive you. That is what Jesus wants us to do.

For ages 9, 12

Jesus knows it is hard when someone hurts you. He says the first step is to talk to that person about what they did, not to gossip or hold a grudge. If they see their mistake and say they are sorry, you are to let it go completely. Forgiving like that takes a lot of faith, but God gives you the strength to do it.

Questions People Ask

Does Luke 17:3 mean I only have to forgive if the person repents?

In context, Jesus is talking about the process of reconciliation between believers. You are to confront the sin, and if the person repents, you grant forgiveness in a way that restores the relationship. But you are still called to forgive from your heart even when the other person does not repent, as Jesus teaches in Matthew 18:35.

What does it mean to "rebuke" someone in this verse?

The Greek word used here (epitimao) means to point out a fault, to confront with the goal of correction. It is not about venting anger or humiliating the person. It is done privately, with respect, and aims to help the brother see his sin so he can turn from it.

How is this verse connected to the apostles asking for more faith in verse 5?

After Jesus gives this command about rebuke and forgiveness, the apostles immediately ask him to increase their faith. They recognized that forgiving someone repeatedly, even seven times a day, requires a supernatural trust in God's grace. The command is hard, but faith makes it possible.

Is rebuking a brother only for church leaders, or for all Christians?

Jesus addresses this to his disciples, which includes all who follow him. The verse begins with "Be careful, if your brother sins against you." It applies to every believer who has been wronged by another believer. You are to take the initiative to speak to them, not wait for a pastor or elder.

What if my brother does not repent after I rebuke him?

Jesus continues the teaching in Matthew 18:15-17, which gives steps for further involvement if the brother refuses to listen. But even if he never repents, you are still called to forgive in your heart and not let bitterness take root (Ephesians 4:31-32). The rebuke is an act of love, not a condition for your own forgiveness.
