After God sent His Spirit upon Gentiles in Acts 10:44-46, just as He had upon those gathered in the temple in Acts 2:1-13, controversy developed as to what the Gentiles needed to do in order to be saved. Despite the fact that Peter and Paul preached the gospel to Gentiles and reported that God’s Spirit came upon them, some in Jerusalem still demanded that Gentiles follow the law of Moses. The Jerusalem Council was convened to reach a verdict on what Gentiles needed to do in order to be saved. James stated that the decision he reached was consistent with the Old Testament prophesies that God would call the Gentiles once Israel was restored.
(1) In Acts 15:1 and 5, some argued that circumcision according to the law was required for salvation. The Lord instituted circumcision for Israelite males when He commanded Abraham to circumcise his son Ishmael and all the males of his household (Gen 17:9-14). Only those foreigners that underwent circumcision were allowed to eat the Passover (Exod 12:43-49). Joshua circumcised the males born during the forty years that Israel traveled in the wilderness before they entered Canaan (Josh 5:1-9). Luke wrote that while Paul and Barnabas were in Antioch, some prophets came from Judea commanding that the Gentiles needed to be circumcised in order to be saved (Acts 15:1). The debate was so sharp that the church in Antioch decided to send Paul and Barnabas to Jerusalem to report all that God had done through them among the Gentiles—apart from the requirement of circumcision. When those in Jerusalem gathered, “Some of the believers from the party of the Pharisees stood up and said, ‘It is necessary to circumcise them and to command them to keep the law of Moses!’” (Acts 15:5). After a period of debate, Peter reminded the delegates at the council that God—in accord with his vision of unclean animals and the command to eat them (Acts 10:9-15)—“made a choice among you, that by my mouth the Gentiles would hear the gospel message and believe” (Acts 15:7). Peter reported that the presence of the Spirit among the Gentiles (Acts 10:17-11:18) was evidence that they had received salvation in the same way that the Jews experienced salvation at Pentecost.
(2) In Acts 15:16-18, James cited Amos 9:11-12 as the basis of his verdict that the difficulties of the law were not to be placed upon Gentiles for salvation. Amos proclaimed that after the Lord disciplined His people, He would restore their fortunes and rebuild their dwelling in the land. “In that day,” the Lord said, “I will restore the fallen booth of David: I will repair its gaps, restore its ruins, and rebuild it as in the days of old, so that they may possess the remnant of Edom and all the nations that are called by My name” (Amos 9:11-12). James interpreted Peter’s work among the Gentiles as the fulfillment of Amos’s prophecy that the Gentiles would seek the Lord. Little more needed to be said. James amended his thesis only briefly, proposing that the Gentile believers should yet be instructed to “abstain from things polluted by idols, from sexual immorality, from eating anything that has been strangled, and from blood” (Acts 15:20).

Acts 16-18
After the Jerusalem Council and a season edifying the believers in Antioch, Paul requested of Barnabas, “Let’s go back and visit the brothers in every town where we have preached the message of the Lord, and see how they’re doing” (Acts 15:36). Luke reported the events of the mission geographically, following Paul and company from Syria as far as Macedonia and the provinces surrounding the Aegean Sea. Many of the cities named in Luke’s report later received correspondence from Paul—epistles that compose much of the New Testament. During Paul’s second journey, the Old Testament shaped his ministry partnerships and defense of the gospel.
(1) In Acts 16:3, Paul had Timothy, the son of a Jewish woman, circumcised before Timothy accompanied him on his second missionary journey. From the time that the Lord instituted circumcision as a covenant with Abraham in Gen 17:1-16, circumcision represented faithful participation in the people of God. Abraham circumcised Ishmael and the rest of his household (Gen 17:1-14), and then Isaac when the boy was eight days old (Gen 21:4). Moses’ wife Zipporah circumcised her son because the Lord threatened Moses’ life (Exod 4:24-26). When Moses established the Passover celebration, he commanded that only circumcised foreigners could partake with Israel (Exod 12:43-48). Because the men of the wilderness generation had not been circumcised, Joshua made them submit to the command before entering Canaan (Josh 5:1-9). When Paul visited Lystra with the good news of the Jerusalem Council—that Gentiles did not need to be circumcised—he found a disciple of note named Timothy. Timothy’s parents were of mixed race and Timothy had not been circumcised according to the custom of his mother’s heritage. Having just been an integral part of the Jerusalem Council, Paul sought to pacify Jew/Gentile tensions. If Timothy were to be accepted in the Jewish synagogues where Paul was headed, Timothy needed to be circumcised. Paul did not require Titus to be circumcised since Titus was of pure Greek descent (Gal 2:1-5).
(2) In Acts 17:22-30, Paul confronted idolatry in Athens by retelling the Old Testament narrative of creation, the tower of Babel, commands against idolatry, and the day of judgement. Paul proclaimed that since God created the universe and gives life and breath to all living creatures, He is Lord of all and does not live in any temple (Acts 17:24-25). Paul’s portrayal of God reflected Genesis 1-2, Psalms 19 and 33, and the numerous Old Testament commands against idolatry (Exod 20:4-6; 32:1-10; Num 25: 1-15; Deut 5:8-10). In Acts 17:26, Paul noted that from one man God created all nations that have spread out over the earth. God scattered humanity by confusing their language after they built the tower at Babel (Gen 11:1-9). In Acts 17:30-31, Paul told the people of Athens that God appointed a day of judgement, reflecting the prophets’ expectation of the Day of the Lord (Isa 13:4-11; 24:21-22; Jer 46:10; Ezek 30:3-4; Joel 3:12-14; Amos 5:18-20; Zeph 1:14-18; 3:8). But Paul stated that on the day of judgement, the Lord would render His verdict upon each individual based upon their faith in Jesus’ resurrection (Acts 17:31). When Paul mentioned Jesus’ resurrection, some scoffed but others, both men and women, believed (Acts 17:32-33).
