Day 1: Jerusalem Council — Must Gentiles Be Circumcised?

Reading: Acts 15

Listen to: Acts chapter 15

Historical Context

Acts 15 records what is arguably the most important ecclesiastical gathering in the history of Christianity. The Jerusalem Council, convened around 49 AD, addressed a question that had been simmering since the conversion of Cornelius in Acts 10 and had now reached a boiling point: must Gentile believers be circumcised and observe the Mosaic law in order to be saved? The stakes could not have been higher. If the answer was yes, Christianity would remain a sect within Judaism, accessible to Gentiles only through full proselyte conversion. If the answer was no, the church would be declaring that the covenant markers that had defined Jewish identity for nearly two millennia were not prerequisites for belonging to the people of God. Either answer carried enormous theological, social, and practical consequences.

The crisis was precipitated by “certain people” who came down from Judea to Antioch and began teaching the Gentile believers, “Unless you are circumcised according to the custom of Moses, you cannot be saved” (15:1). Luke does not identify these teachers precisely, but they appear to be the same faction Paul calls the “circumcision party” or “false brothers secretly brought in” (Galatians 2:4). Their position was not irrational. Circumcision was the sign of God’s covenant with Abraham (Genesis 17:9-14), commanded to be observed “throughout your generations” as “an everlasting covenant.” The Mosaic law elaborated this covenant in exhaustive detail. Jesus himself was circumcised, kept the Sabbath, and declared that he came not to abolish the law but to fulfill it (Matthew 5:17). Why, then, should Gentiles be exempt from the very terms of the covenant they claimed to be entering through its Messiah?

Paul and Barnabas engaged in “no small dissension and debate” with these teachers at Antioch (15:2), and the church decided to send them to Jerusalem to consult with the apostles and elders. This was not a surrender of theological conviction but a recognition that the question required a definitive answer from the whole church, not just one local congregation. The journey itself was evangelistic: Paul and Barnabas traveled through Phoenicia and Samaria, “reporting the conversion of the Gentiles” and causing “great joy to all the brothers” (15:3). When they arrived in Jerusalem, however, they encountered immediate opposition from believers who belonged to the party of the Pharisees, who insisted that Gentile converts “must be circumcised and required to keep the law of Moses” (15:5).

The council proceedings, as Luke records them, feature three major speeches. Peter speaks first, recounting the Cornelius episode and drawing a sweeping theological conclusion: “God, who knows the heart, bore witness to them, by giving them the Holy Spirit just as he did to us, and he made no distinction between us and them, having cleansed their hearts by faith” (15:8-9). Peter’s argument is experiential and pneumatological – the Holy Spirit himself has already settled the question by falling on uncircumcised Gentiles. To require circumcision now would be to “put God to the test by placing a yoke on the neck of the disciples that neither our fathers nor we have been able to bear” (15:10). The admission is remarkable: Peter acknowledges that even Israel found the law an unbearable burden. Salvation has always been by grace.

Paul and Barnabas then recount “all the signs and wonders God had done through them among the Gentiles” (15:12). Their testimony is narrative rather than argumentative – a catalogue of divine activity that speaks for itself. The assembly falls silent, awed by the evidence of God’s work.

James, the Lord’s brother and apparent presiding officer of the Jerusalem church, delivers the decisive judgment. His speech is the most theologically sophisticated of the three. He quotes Amos 9:11-12 from the Septuagint, which prophesies that God will rebuild the fallen booth of David “so that the rest of mankind may seek the Lord, and all the Gentiles who are called by my name” (15:17). The key move is hermeneutical: James reads the Old Testament prophets as predicting the inclusion of Gentiles as Gentiles – not as converts to Judaism – within the restored people of God. The prophetic vision was always larger than the circumcision party imagined.

James’ judgment is that Gentile converts should not be “troubled” with circumcision but should abstain from four things: food polluted by idols, sexual immorality (porneia), the meat of strangled animals, and blood (15:20). These four requirements have generated centuries of scholarly debate. The most persuasive interpretation connects them to the “Noahide laws” or the holiness code of Leviticus 17-18, which applied to both Israelites and resident aliens (gerim) living among them. In other words, James is not imposing a reduced Torah but identifying the minimal ethical and dietary standards that would make table fellowship between Jewish and Gentile believers practically possible. The requirements are pastoral, not soteriological – they concern community life, not salvation.

The council’s decision is formalized in a letter carried by Paul, Barnabas, Judas (called Barsabbas), and Silas to the Gentile churches. The letter’s language is significant: “It has seemed good to the Holy Spirit and to us” (15:28). The phrase claims divine authorization for the decision while acknowledging human deliberation. The council modeled a process of theological decision-making that combines Scripture, Spirit-led experience, apostolic testimony, and communal discernment – a process the church would need again and again in the centuries to come.

The chapter closes with an unexpected rupture. Paul and Barnabas disagree sharply over whether to take John Mark, who had deserted them in Pamphylia during the first journey (13:13). The disagreement is so intense that they part ways: Barnabas takes Mark to Cyprus, while Paul chooses Silas and heads overland through Syria and Cilicia. Luke offers no theological judgment on the dispute. The church’s greatest missionary partnership has dissolved over a question of character and second chances – a reminder that even Spirit-filled leaders remain fully human.

Key Themes

• Salvation by grace alone – The council’s definitive declaration that Gentiles are saved through faith in Jesus without Torah observance, establishing the theological foundation for the universal church
• Scripture, Spirit, and community in discernment – The council models theological decision-making through the integration of prophetic Scripture, the Spirit’s testimony, and communal deliberation
• The tension between unity and conviction – The Paul-Barnabas split reveals that genuine disagreements among godly leaders are part of the messy reality of the church’s mission

Connections

• Old Testament Roots: Genesis 17:9-14 (the circumcision covenant); Amos 9:11-12 (restoration of David’s booth and Gentile inclusion); Leviticus 17-18 (laws for resident aliens that may underlie the council’s four requirements)
• New Testament Echoes: Galatians 2:1-10 (Paul’s own account of the Jerusalem meeting, likely the same event); Romans 3:21-31 (justification by faith apart from the law); Ephesians 2:8-9 (saved by grace through faith)
• Parallel Passages: Acts 10:1-48 (the Cornelius conversion Peter references); Acts 11:1-18 (Peter’s earlier defense of Gentile inclusion)

Reflection Questions

1. What three lines of evidence does the council consider – Peter’s experience, Paul and Barnabas’ missionary testimony, and James’ scriptural argument – and how does each contribute to the final decision?
2. Why does James choose requirements from Leviticus 17-18 rather than from the Ten Commandments or some other portion of the law, and what does this reveal about the purpose of the four prohibitions?
3. When your church or community faces a divisive theological or practical question, what elements of the Jerusalem Council’s deliberation process – Scripture, experience, the Spirit’s witness, communal discernment – tend to be emphasized, and which are neglected?

Prayer

Sovereign God, you guided your early church through its most dangerous theological crisis by the wisdom of your Spirit and the clarity of your Word. Thank you that salvation rests not on our performance but on your grace. Give us the humility of Peter, the courage of Paul, and the wisdom of James as we navigate the questions of our own day. Teach us to hold firm to what is essential and to extend grace in what is not. Amen.
