In 2 Peter 3:1-2, Peter was referring to the command that Jesus gave the disciples in the Upper Room:
John 13:34
A new commandment I give to you, that you love one another: just as I have loved you, you also are to love one another.
But wait, how was that commandment new? Is this command not old?
When asked “Teacher, which is the great commandment in the Law?”, Jesus responded with the old commandment:
Matthew 22:37-39
And he said to him, “You shall love the Lord your God with all your heart and with all your soul and with all your mind. This is the great and first commandment. And a second is like it: You shall love your neighbor as yourself.
Jesus quoted it from the ceremonial and law-filled book of Leviticus:
Leviticus 19:13-18
“You shall not oppress your neighbor or rob him. The wages of a hired worker shall not remain with you all night until the morning. You shall not curse the deaf or put a stumbling block before the blind, but you shall fear your God: I am the Lord.
“You shall do no injustice in court. You shall not be partial to the poor or defer to the great, but in righteousness shall you judge your neighbor. You shall not go around as a slanderer among your people, and you shall not stand up against the life of your neighbor: I am the Lord.
“You shall not hate your brother in your heart, but you shall reason frankly with your neighbor, lest you incur sin because of him. You shall not take vengeance or bear a grudge against the sons of your own people, but you shall love your neighbor as yourself: I am the Lord.
This is not about forgiveness; this is about impartial and “frank” justice that when executed leaves no room for vengeance or a grudge.
The ESV translates it “reason frankly” (yāḵaḥ). But the NIV does a better job in making it mandatory and the reason behind it.
Leviticus 19:17 (NIV)
“‘Do not hate a fellow Israelite in your heart. Rebuke your neighbor frankly so you will not share in their guilt.
If your neighbor sins against you, and instead of “getting it out in the open”, you harbor hatred in your heart and impair the relationship, then you become a fellow sinner.
The command is actually yāḵaḥ yāḵaḥ. It is repeated twice (The ancient highlighter), first conjugated as infinitive absolute and then as imperfect (future). This is not optional. That is, if you don’t rebuke your neighbor, you sin.
So, the old command is not a command to forgive, but rather to rebuke and execute justice but in a way that you, being a fellow follower of the law, would want it done to you. We are to “love your neighbor as yourself” – without impartiality or hatred and with a goal of restoring the relationship.
The new commandment is different, because it asks us instead to love as Jesus did (“just as I have loved you”) rather than with that reciprocal justice:
- Jesus in the Upper Room lowered Himself from a king to a servant to wash their feet.
- Before the Sanhedrin, He lowered Himself from a prophet speaking forth the word of God, to a subject hearing their sentence as they misapplied the Law.
- And on the cross He lowered Himself from being the priest to being the sacrifice.
This makes the two commands very different:
In the old command, the root word for the Hebrew “neighbor” (rēaʿ) is “flock” and is well translated as “fellow-citizen”. Two arguing neighbors are on equal footing before the same law (very similar to two Christians in the same congregation executing Matthew 18:15-20). This is justice.
But not so in this new command. In this new commandment, the Greek for “one another” (allēlōn) does not carry any boundary of neighborhood or law. In the new command, love extends to those not bound to reciprocate with justice. We are asked not to stay on equal footing, but rather to forgive, as Jesus did, even injustice.
Luke 23:34a
And Jesus said, “Father, forgive them, for they know not what they do.”
Periodically one should stand on the foundation of the first half of Romans, and just read Romans 12-16 to get a clear picture of what it means to be a living sacrifice, and so fulfill this “new command”. For it is this command that we are to patiently obey as we listen to the scoffers until His return (2 Peter 3:4).
