GALATIANS 2:11–21
Why Did Paul Confront Peter?
Paul has just told us that Peter, James, and John recognized his work among the Gentiles.
They agreed that Gentiles did not have to be circumcised to belong to Christ.
Then something surprising happens.
Peter comes to Antioch.
And Paul confronts him publicly.
Why?
Because Peter's behavior contradicted the gospel he believed.
Peter Had Been Eating With Gentiles
Paul says:
“When Cephas came to Antioch, I opposed him to his face, because he stood condemned.” — Galatians 2:11
What had Peter done?
Before certain men came from James, Peter had been eating with Gentile Christians.
That tells us something important.
Peter apparently understood that these Gentile believers were his brothers and sisters in Christ.
He could sit at the same table with them.
No circumcision was required.
No Jewish boundary separated them.
Then something changed.
Peter Pulled Away
Paul explains:
“But when they came, he began to draw back and separate himself from the Gentiles because he was afraid of those who belonged to the circumcision group.” — verse 12
Peter's theology apparently had not changed.
His behavior had.
He became afraid.
So he withdrew from the Gentile Christians.
Think about what that action communicated.
Yesterday Peter ate with them.
Today he would not.
What were those Gentile Christians supposed to think?
Are we really part of God's family—or aren't we?
Other Christians Followed Peter
Peter was an influential man.
His actions affected others.
Paul says:
“The other Jews joined him in his hypocrisy, so that by their hypocrisy even Barnabas was led astray.” — verse 13
Even Barnabas.
Barnabas had worked alongside Paul among Gentiles.
Yet he too was pulled into the separation.
That shows us how powerful social pressure can be.
People may know what is right and still act contrary to it because they fear what others will think.
What Was Really Wrong?
Paul tells us exactly why he confronted Peter:
“When I saw that they were not acting in line with the truth of the gospel...” — verse 14
That's the key sentence.
Peter's behavior was not in line with the gospel.
The gospel wasn't merely a doctrine to be preached.
It changed who could sit together at the table.
If Jew and Gentile were one in Christ, Peter could not behave as though Gentile Christians were second-class members of God's family.
Paul Asks Peter a Question
Paul says to Peter:
“You are a Jew, yet you live like a Gentile and not like a Jew. How is it, then, that you force Gentiles to follow Jewish customs?” — verse 14
Peter wasn't apparently standing up and preaching:
Gentiles must become Jews.
His behavior was communicating it.
By withdrawing from them, he was placing pressure on Gentile believers to adopt Jewish practices if they wanted full fellowship.
Paul would not let that pass.
Justified by Faith in Christ
Now Paul moves into the theological heart of the matter.
He says:
“A person is not justified by the works of the law, but by faith in Jesus Christ.” — verse 16
This is one of the best-known statements in Galatians.
But notice where it appears.
It comes in a discussion about Jew and Gentile.
Peter's separation from Gentiles provides the immediate setting.
That doesn't make Paul's statement unimportant for salvation.
Quite the opposite.
It helps us understand what Paul is arguing.
Jewish Christians did not stand righteous before God because they possessed the Law.
Gentile Christians did not need to come under that Law to become righteous.
Both needed Christ.
What Does Paul Mean by “Works of the Law”?
This phrase will become increasingly important as we continue.
We should resist the temptation to define it before Paul develops his argument.
But the context has already given us important clues.
The controversy includes:
circumcision,
Jewish identity,
and the Law.
Paul is not arguing that faith means we can ignore God.
He is arguing that people are not justified by placing themselves under the Law of Moses.
Their standing with God is through Christ.
We'll let Paul develop that argument rather than importing our own definition into his words.
Paul Had Died to the Law
Paul says:
“For through the law I died to the law so that I might live for God.” — verse 19
That's a striking statement.
Paul had not abandoned God.
He had died to the Law so that he could live for God.
For Paul, leaving the Law as the basis of covenant life did not mean leaving God.
It meant finding life in Christ.
“I Have Been Crucified With Christ”
Then comes one of Paul's most memorable statements:
“I have been crucified with Christ and I no longer live, but Christ lives in me.” — verse 20
Christianity isn't merely exchanging one list of regulations for another.
Paul describes something much deeper.
His old life has been crucified with Christ.
Now Christ lives in him.
And Paul says:
“The life I now live in the body, I live by faith in the Son of God, who loved me and gave himself for me.”
Notice how personal Paul's language becomes.
He loved me.
He gave Himself for me.
Then Paul Makes the Issue Crystal Clear
Paul concludes:
“I do not set aside the grace of God, for if righteousness could be gained through the law, Christ died for nothing!” — verse 21
There is Paul's argument in one sentence.
If righteousness could come through the Law, what was the cross for?
Christ's death tells us that the Law was not the final answer to humanity's problem.
Christ was.
Peter's Mistake Was Bigger Than a Meal
Now we can see why Paul reacted so strongly.
This wasn't merely an argument over where Peter ate lunch.
The table represented something much bigger.
Are Jewish and Gentile Christians truly one family in Christ?
Peter knew the answer.
But for a moment, he failed to live like it.
Paul called him back to “the truth of the gospel.”
Follow Paul's Argument
Paul's argument continues to build.
Chapter 1:
My gospel came from Christ.
Galatians 2:1–10:
The Jerusalem apostles recognized that gospel, and Titus was not required to be circumcised.
Now Galatians 2:11–21:
Even Peter had to live consistently with that gospel.
And now Paul is ready for his next major argument.
He turns directly to the Galatians and asks them a question:
How did you receive the Spirit?
Was it through the Law?
Or through faith?
Paul is about to take us back even farther than Moses.
He is going to take us to Abraham.
