Matthew 5:21-24 (LEB) says:
“You have heard that it was said to the people of old, ‘Do not commit murder,’ and ‘whoever commits murder will be subject to judgment.’ But I say to you that everyone who is angry at his brother will be subject to judgment, and whoever says to his brother, ‘Stupid fool!’ will be subject to the council, and whoever says, ‘Obstinate fool!’ will be subject to fiery hell. Therefore if you present your gift at the altar and there remember that your brother has something against you, leave your gift there before the altar and first go be reconciled to your brother, and then come and present your gift.”
If you give this passage a cursory reading you miss something very important. It’s easy to miss the change in concentration. In the first part, Jesus is warning that being anger is the source of murder, and a cause of judgment. It is natural to imagine verses 23f address your response to being angry at your brother. However, it says something very different.
In verse 23, Jesus says “If you remember that your brother has something against you…” This is not saying “Do this, if you remember your brother has something against you, because you are in danger of judgment.” This is actually saying, “Do this, if you remember your brother has something against you, because your actions have put your brother in danger of judgment.” Jesus is telling us to take care for our brother’s emotional condition. He is telling us to care more for our brother’s spiritual well-being than even for our religious observations: “Leave your offering at the altar and go…” In this passage it is the brother who is angry. This anger tempts the brother to sin, and puts him in danger of judgment. Jesus places responsibility upon the errant disciple to go and make things right with one he or she has angered.
