What does the book of Acts teach about God’s mission in the early Church? As the narrative unfolded, the author Luke revealed how the Lord arranged every action and event to magnify His saving name in the world and transform communities into His singular image from glory to glory (2 Cor 3:18b). The change agent is the Spirit of Jesus Christ. His salvific actions knew no bounds, beginning first with the Jews and then to the Gentiles. It crossed culture, ethnicity, language, socio-economics, and nations. His message spread in three phases: Jerusalem, Judea, Samaria, and the ends of the earth (Acts 1:8), transcending challenges and achieving revival. Some view the supernatural events in the Book of Acts as exclusive to the early Church. Believers can rest assured that Jesus gives them the same tools today, including knowledge, access, authority, and power, through new birth so that they can utilize all the rights, benefits, and privileges of the Kingdom.
Tumultuous Birth
The birth of the church occurred in an environment of opposition, characterized by the presence of Palestinian Judaism, the Jewish Diaspora, Hellenists, and Romans. The earliest Christians considered themselves Jews who believed in the long-awaited Messiah, yet they continued to observe Jewish traditions, such as the Sabbath and worship in the Temple. However, fellow Jews mocked (2:13), arrested (4:1; 5:17), and persecuted (7:58; 8:1). Greeks considered Christians (and Jews) pagans because they worshiped one God as opposed to multiple. Christians also disrupted the local economy. Local citizens from Amastris, modern-day Amasra in Turkey, had approached Pliny that meat sales for sacrificial services had decreased because of the Christians.1 People additionally accused them of engaging in secret rituals involving sexual immorality, as well as of killing children, consuming their organs, and drinking their blood.2 To add to false accusations and misunderstandings, widespread and harsh persecutions existed through to Constantine in 324 AD and later. Nonetheless, Christianity became the dominant religion in the Roman Empire by the fifth century.3
Early Christians
Early Christian communities saw themselves as Jews from the true assembly of a renewed Israel. They still attended temple and obeyed the Law, even though they had their own identity. They did not consider themselves separate from Judaism, but distinguished themselves as a faction identifying themselves by Jesus’ name but calling themselves Jews. They acknowledged Jesus as the Messiah and proclaimed His resurrection and imminent return to fulfill God’s kingdom. The group called themselves the ekklesia (or assembly or church), though they adhered to the Law and attended the temple. On the other hand, they called on the name of Jesus in water and Spirit baptism. They also gathered regularly to study the “apostles’ doctrine, and fellowship, and in breaking of bread, and in prayers” (Acts 2:42). As time progressed, they had difficulty getting along with the Jews and Romans. The Romans viewed Christians as atheists since they worshiped a single, invisible God. Like their Jewish brothers, they would not acknowledge or worship the emperor as a deity.4
Jerusalem (Acts 2-5) 一 Local: Same Culture and Religion
“But you shall receive power when the Holy Spirit has come upon you; and you shall be witnesses to Me in Jerusalem, and in all Judea and Samaria, and to the end of the earth" (Acts 1:8).
The disciples encountered devout men from every nation under heaven representing diaspora from fifteen nations (Acts 2:5-11). A multitude of emotions ensued with the utterance of tongues. Some expressed amazement because they heard it in their own language (Acts 2:6,11). Others mocked them, saying they were full of new wine (2:13). Peter’s pointed address to Israel followed. The 120 spoke in tongues in a public place. Common to that setting, people would openly mock or heckle others. Accusing them of being drunk rubbed in the insult. While Greeks embraced a drunkenness for a “frenzied inspiration by the gods,” Jews viewed intoxication as sinful.55 Nevertheless, this supernatural event of the outpoured Spirit caught the attention of those at the feast and gave rise for Peter to explain it. It also catalyzed Peter’s evangelistic proclamation of the gospel message and subsequent people who believed, calling on the name of the Lord (Acts 2:21; 38).
Three thousand were baptized that same day (2:41), representing the fulfilled firstfruits of the new covenant. With this event, Jerusalem became the initial base of operations and staging area for the spread of the gospel. The apostles did signs and wonders.66 The church membership grew quickly, beginning with the 120 disciples and increasing to 3,000 on the day of Pentecost (Acts 2:41) and later to 5,000 at Solomon’s Portico (4:4). However, the church continued to grow daily (2:47; 5:12-16).
Several factors drove the immediate increase. First and foremost, the power from Jesus’ indwelt Spirit and authority from His Name created the influx. The Spirit let them hear the 120 speaking in tongues, each in their own language. Likewise, I believe the Spirit gave them understanding of Peter’s speech as well. It led to “Men and brethren, what shall we do?” (Acts 2:37) and 3,000 souls baptized in the Name. Scripture also mentioned teachings, healings, and signs and wonders in the name of Jesus prior to the Lord growing His church. In fact, Luke mentioned two different accounts of Peter teaching and healing. Each resulted in his arrest, and both times, the Lord added believers to His church. After Peter healed the lame man and taught in the Name, 5,000 were healed (Acts 3:6, 16; 4:4). Even though the priests and Sadducees told him not to teach in the Name (5:28), “believers were increasingly added to the Lord, multitudes of both men and women” (5:14).
Second, Scripture doesn’t mention growth figures beyond this in the first four chapters. However, consider that the initial 3,000 came not only from the local population but also from a multinational diaspora within the Roman Empire present at the festival. They, in turn, took the gospel with them outside the boundaries of Jerusalem to their home country. In reality, the number of early Christians in the period represented from Acts 1-4 more than likely surpassed the listed amount.
Third, they formed a tight-knit, covenant community. The new believers continued steadfastly in the apostles’ doctrine, fellowship, breaking of bread, and prayer (v. 42). They also shared possessions and goods as members had needs. While they broke bread from house to house, they also continued daily in one accord in the temple (2:42-47). The members supported their spiritual growth and provided mutual support.
Judea (Acts 6-7) 一 Culturally Similar But Some Religiously Different
While the early church centered on the formation of the ekklesia, or the assemblage, as described in Acts 1:4, it concentrated on acts of diakonia as Christianity spread regionally in Judea. Diakonos means “one who, by virtue of the office assigned him by the church, cares for the poor and has charge of and distributes the money collected for their use.” 7The New Testament highlights how the apostles and believers carried out their God-given mission through serving others in the name of Jesus. Thus began the ministry of the church with Hellenist Jews.
Hellenist Jews
Now in those days, when the number of the disciples was multiplying, there arose a complaint against the Hebrews by the Hellenists, because their widows were neglected in the daily distribution (Acts 6:1).
As the church continued to grow, Acts 6:1 mentioned the conflict regarding the distribution of food to Christian widows of Hellenist Jewish descent within the early church community. Who were the Hellenist Jewish Christians? According to F. F. Bruce, the Hebrews spoke Aramaic and lived in the Palestine region. Conversely, the Hellenists, also Jewish, spoke Greek and practiced a Greek way of life.8 Hellenistic Jews were people from the first-century Jewish dispersion who lived in Jewish communities outside of the Holy Land. C. Peter Wagner noted that Hellenistic practices indicate these Jews “were molded to some degree by Greek culture, including the Greek language.”99 Since the Romans recognized Judaism as an authorized religion, it protected the Hellenist Jewish (Diaspora) communities outside Jerusalem and across the Roman Empire. While they did not participate in Greek civic life, they spoke the language daily and in their synagogues. As the Jewish Hellenists scattered abroad, they interacted with people from other religions. Their actions resulted in them making converts (proselytes) and, thus, gathering God-fearers, ethnic Gentiles who practiced Judaism. Later, Christian missionaries evangelized to these God-fearers.
The Twelve and the multitude of disciples decided to choose men full of the Holy Spirit and wisdom to distribute food to the Hellenist widows, rather than leave ministering the Word (6:2). They chose Stephen, Philip, Prochorus, Nicanor, Timon, Parmenas, and Nicolas a Jewish proselyte from Antioch一All Hellenists with Greek names (6:5). Stephen, one of the six, did great wonders and signs among the people. He caught the attention of certain men from the Synagogue of the Freedmen who disputed with Stephen. Since they could not match his wisdom and the Spirit by which he spoke, they stirred up the people, elders, and scribes and brought him before the council. After Stephen’s poignant address to them, they cried fiercely, charged upon him, dragged him outside the city walls, and stoned him. Paul, then Saul, entered the scene persecuting the church (8:1-3). With the exception of the apostles, Christians moved throughout Judea and Samaria to escape oppression. The Gospel followed the scattered. After Stephen’s martyrdom, early believers congregated in Antioch of Syria (Acts 11:19–26). Antioch of Syria was located approximately 300 miles north of Jerusalem, in modern southern Turkey near Syria. It was here that believers first became known Christians. Paul launched his missionary journeys from Antioch.
Samaria (Acts 8) 一 Same Language, Different Culture, Ethnicity, and Religion
As Christianity spread, Philip came to the forefront of mission in Samaria. The Samaritans lived north of Judea and south of Galilee. They were a people of mixed ethnicity, exiled Israelites who remained in Assyria after the conquest of the northern kingdom of Israel in 722 BC (2 Kgs 17) and intermarried with the local population. Philip proclaimed the gospel and performed many miracles there. Unclean spirits were driven out, and the paralyzed and lame were healed. Great joy resulted. Now, when the apostles in Jerusalem heard that the people of Samaria had received the word of God, they sent Peter and John to them. They prayed that they might receive the Spirit and also laid hands on them, and the Samaritans received the Holy Ghost (8:17).
Philip also ministered to an Ethiopian eunuch on the road that goes down from Jerusalem to Gaza as directed by an angel (8:26-27). After encountering him, he heard the eunuch reading from Is 53:8, and he preached Jesus to him. As they went down the road in the middle of a desert, water appeared. Some traditions consider the eunuch to be the first gentile convert. Scripture does not make it clear. Nevertheless, he saw no reason why he couldn’t be baptized. Upon request, Philip baptized him. As the eunuch came up out of the water, the Spirit snatched (Grk: harpazō) Philip away. Philip was found next in Azotus near the coast, located twenty-five miles north of Gaza and thirty-five miles west of Jerusalem. From there, he made his way up to Caesarea (8:40).
End of the Earth (Acts 9-28) 一 Different Geographically, Religiously, Culturally, Linguistically, and Ethnically
Three key events turned mission in a new direction: Paul’s conversion and subsequent trips to minister to the Gentiles, Peter and the salvation of Cornelius a Roman centurion and his household, and the Jerusalem Council.Peter’s sermon in Acts 2, made it clear that the promise of the Spirit is for all believers equally: “For the promise is for you and your children and for all who are far away, as many as the Lord our God will call to himself” (NET Acts 2:39). 1010 With the inclusion of Gentiles, conflict arose from Jewish Christians who believed Gentiles should follow the Torah requirements for circumcision.
An unlikely candidate as a Christian convert, Paul (once Saul) was born in Tarsus as a diaspora Jew in a culture of strict adherence to the Law. However, Jesus knew Paul from the womb as a chosen vessel to bring the Gospel to the Gentile nations (9:15). His parents, both Pharisees, abhorred anything Greek. Gamaliel trained him at thirteen in Judea, where Paul mastered Jewish history, Psalms, and the works of the prophets during the six years he spent dissecting the Scriptures. He also spoke fluent Greek and passable Latin and had a familiarity with Greek philosophy and literature. The power of Jesus’ Spirit fueled and directed Paul’s knowledge and boldness to take the gospel message to the Gentiles on three mission trips. He carried the Gospel from Antioch of Syria all the way into Europe (Acts 13–14; 15:36–18:22; 18:23–21:17).
In another conversion account, the Lord flipped the tables on established Jewish social beliefs and norms through Peter, even though He commissioned him to preach to the Jews. The conversion of Cornelius and his household in Acts 11 went against the salvation protocol from the Circumcision faction. While praying in Joppa, Peter saw a vision of a sheet from heaven filled with all kinds of animals, including those not kosher. When told to eat, he refused, but the voice replied, “What God has cleansed, you must not call it common” (10:15). Soon messengers from Cornelius, a devout Gentile, arrived, and the Spirit sent him with them to Caesarea. There, Cornelius had gathered his household to hear God’s word.1111 Peter declared that no person should be called unclean. As he preached about Jesus, the Holy Ghost fell on all who heard, and they spoke in tongues and magnified God. To Peter’s astonishment, the Spirit was poured out on Gentiles too. And, Peter baptized them (Acts 10:1–48).
A third event marked a critical juncture in Gentile conversion. Galatians 2:1-10 described the conflict as false brethren from the church in Jerusalem contending that Gentiles must be circumcised to be saved. Acts 15:5 described it further as a sect of the Pharisees who felt that it was not enough that Gentiles should believe in the Lord Jesus Christ. Gentiles had to undergo circumcision and keep the law of Moses. After the apostles and elders disputed the matter, Peter arose and made it clear that God makes no distinction between Jews and Gentiles (Acts 15:7-9). Gentile salvation harmonized with Old Testament prophecy (Amos 9:11-12). The yoke of the law that even Israel’s fathers could not bear did not qualify them or form their identity as Christians (Acts 15:10).
Close
In the initial stages of the early church, the Spirit formed a community with new believers in Jerusalem. They came together in covenant with the Lord. Acts 2:42 shows that they continued steadfastly in the apostles’ doctrine and fellowship, in the breaking of bread, and in prayers, as they established their newfound identity (Acts 2:42). In addition to the 120 disciples from the upper room, people from fifteen nations who were there for the Feast of Pentecost believed that day. Not only did locals hear the gospel message, but the diaspora Jews took it with them to their home countries. Additionally, since the multitudes included proselytes who converted to Judaism (Acts 2:11), Gentiles also received salvation.
