Living as a Gentile

In Galatians 2, Paul describes a dramatic public conflict with Cephas, better known as Peter. The scene occurred in Antioch, where Jewish and Gentile followers of Jesus had been sharing fellowship. Then “certain people came from James,” and Peter withdrew from table fellowship with Gentile believers. Barnabas and others followed his example. Paul confronted Peter openly because, he says, they were “not acting in line with the truth of the gospel” (Gal 2:14).

This episode is often used to support a familiar picture: Peter, like Paul, had stopped living as a Torah-observant Jew. When visitors from Jerusalem arrived, he supposedly returned to Jewish practice out of fear. Paul then rebuked him for abandoning Christian freedom.

But was it really what Paul meant?

A closer reading, especially alongside Acts 10, Acts 15, and the Jewish world of the first century, suggests a different possibility. The issue may not have been whether Peter ate kosher food, observed the Sabbath, or remained Jewish. The issue was whether Gentiles who trusted Israel’s Messiah could be welcomed as full members of God’s people without becoming Jewish proselytes.

“We Are Jews by Birth”

Paul’s words are striking:

“We are Jews by birth and not Gentile sinners; yet we know that a person is not justified by works of the law but through faith in Jesus Christ” (Gal 2:15–16).

Modern readers may find the phrase “Gentile sinners” uncomfortable, but it reflects a recognizable Jewish way of speaking in the Second Temple period. It did not necessarily mean that every Gentile was personally more immoral than every Jew. Rather, Gentiles were often viewed as people outside Israel’s covenant, outside the Torah’s way of life, and frequently associated with idolatry.

Jewish writings from before and around the time of Jesus reflect this sharp boundary between Israel and the nations. These texts should not be used to condemn Judaism. They help us hear Paul within his world. He was not a former pagan who had discovered a religion that contradicted Judaism. He was a Jewish Pharisee who had become convinced that Jesus was Israel’s Messiah and that God’s promises to Israel were now making salvation available to the nations.

That is why Galatians is not an argument against the Torah of Moses. Far from it! It is an argument against requiring Gentiles to become Jews in order to be recognized as first-class citizens in the Kingdom of Israel’s God.

What Did Peter Do Wrong?

Paul asks Peter:

“If you, though a Jew, live like a Gentile and not like a Jew, how can you compel the Gentiles to live like Jews?” (Gal 2:14).

The Greek verbs behind “live like a Gentile” and “live like a Jew” do not automatically settle the question of food laws or Jewish practice. The language may refer broadly to social and covenantal life. Peter had been living in open fellowship with Gentile believers. By withdrawing, he acted as though such fellowship was improper unless those Gentiles first adopted a fully Jewish identity.

This is why Paul’s rebuke was so serious. Peter’s withdrawal communicated something powerful without words: “You may believe in Israel’s Messiah, receive the Spirit, and worship Israel’s God, but you are still not fully acceptable at the table unless you become like us.”

Paul could not allow that message to stand.

Peter’s error was not necessarily that he had ceased observing Torah and then suddenly resumed it. Rather, he had acted inconsistently with the revelation God had already given him. In Acts 10, Peter receives a vision involving animals considered unclean under the Torah. Many readers immediately assume that the vision gave Peter permission to abandon Jewish dietary practice. But Peter himself tells us how he understood it:

“God has shown me that I should not call any person common or unclean” (Acts 10:28).

The point of the vision was people.

Immediately after the vision, Peter was summoned to the home of Cornelius, a Gentile who feared Israel’s God. Peter entered his house, preached Jesus the Messiah, and watched the Holy Spirit fall upon Cornelius and his household. This astonished the Jewish believers who had come with him, because the same Spirit poured out at Pentecost was now given to uncircumcised Gentiles.

Peter’s conclusion was clear: God had accepted them.

Proselytes and God-Fearers

An important distinction helps clarify the controversy. A proselyte was a Gentile who had converted fully to Judaism. Such a person entered Israel’s covenantal life through circumcision, immersion, and participation in Jewish communal practice. A God-fearer, by contrast, worshiped the God of Israel and respected Jewish beliefs and ethics without becoming a full proselyte.

Cornelius appears to have been such a God-fearer. He prayed to Israel’s God, gave generously, and was respected by the Jewish community (Acts 10:1–2, 22). Yet he was uncircumcised.

The great question facing the early Jesus movement was this: Must Gentiles such as Cornelius become Jews before they can receive the blessings of the Messiah?

The Jerusalem Council in Acts 15 answered: no.

Peter reminded the council that God gave the Holy Spirit to Gentiles “just as he did to us,” making no distinction between Jewish and Gentile believers by cleansing their hearts through faith (Acts 15:8–9). James then affirmed that the inclusion of the nations fulfilled the prophetic hope that the God of Israel would call people from among the Gentiles for his name.

The council did not tell Jewish believers to stop being Jewish. Neither did it demand that Gentile believers undergo proselyte conversion. Gentiles were asked to avoid idolatry, sexual immorality, strangled meat, and blood, practices closely connected with pagan worship and necessary for fellowship in mixed communities (Acts 15:20).

The result was not a religion detached from Israel. It was a renewed messianic movement in which Jews remained Jews and Gentiles came to Israel’s God through Israel’s Messiah.

Justification and the Gift of Life

Paul’s central point in Galatians is that neither Jews nor Gentiles are justified before God by “works of the law.” In this setting, the phrase cannot be reduced simply to good deeds. It includes the boundary-marking practices and covenantal identity that distinguished Jews from Gentiles, especially when those practices were imposed upon Gentiles as the condition for full acceptance.

Paul does not say that the Torah is evil. Elsewhere he calls it “holy, righteous, and good” (Rom 7:12). Nor does he dismiss Israel’s calling. Instead, he insists that Jewish covenant identity cannot become a barrier preventing Gentiles from entering God’s family through faith in Jesus.

Peter and Paul were Jews. They knew the Torah. They loved Israel’s God. Yet neither could claim justification because of Jewish birth, circumcision, food practices, or any other privilege. They stood before God, like Cornelius, entirely by grace.

This is why Paul can write:

“I have been crucified with Christ and I no longer live, but Christ lives in me” (Gal 2:20).

The heart of Paul’s message is life. Jews and Gentiles alike were spiritually dead and are made alive through the faithfulness of Jesus the Messiah and through faith in him. The same Holy Spirit who transformed Peter and Paul transformed Cornelius’s household.

Therefore, Peter’s withdrawal in Antioch was not a small matter of table etiquette. It denied, in practice, the shared life God had given to Jewish and Gentile believers alike.

The gospel did not require Jews to stop being Jews. Nor did it require Gentiles to become Jews. It proclaimed something far more radical: through the Jewish Messiah, the God of Israel was creating one family from Israel and the nations.
