The book of Acts identifies the followers of Jesus as a Jewish sect called both “Nazarenes” and the “Way” (Acts 19:9, 23; 22:4; 24:14, 22). Like modern Christianity with its many denominations, first-century Judaism had numerous sects including the Pharisees, Sadducees, Essenes, Nazarenes, etc. Those who belonged to the Way believed God was going to restore the kingdom of Israel; install Jesus as the ruler of this kingdom; resurrect Jews who had died; and destroy all of the enemies of Yahweh, the god of Israel (Matt 21:33-45, 13:37-43; Mark 16:16; Luke 12:31-48). (With the exception of Jesus being installed as the ruler, the Pharisees held the same beliefs.)
Jesus repeatedly warned his fellow Jews that only those who faithfully obeyed Yahweh’s commands would have a place in the coming kingdom (Matt 5:19, 16:27).
Followers of Jesus were likely shocked when Jesus was crucified since they believed he was the prophesied Davidic king who would restore their independence and then reign over God’s kingdom (Matt. 21:9; Mark 11:9-10; John 12:13); however, the apostles assured other members of the Way that although Jesus had died, Yahweh raised him from the dead and took him to heaven from where he would soon return (Acts 3:18-26).
Jesus’ followers believed that by resurrecting and exalting Jesus to heaven, Yahweh was declaring that Jesus could reign over the kingdom of God and that he was worthy of worship alongside of himself. In essence, Jesus was made a god. (The Greek trinitarian concept had not yet been invented.)
As Jewish followers of Jesus waited for him to return with his army of angels, a Pharisee named Saul saw a bright light and heard a voice, which identified itself as Jesus in heaven. Jesus told Saul that he had been chosen to be an apostle to the Gentiles.
Saul, who began calling himself Paul, met with the leaders of the Way, and after receiving their blessing, began traveling to various locations outside of Israel to speak in diaspora synagogues to Jews and God-fearing Gentiles. His message was that Jesus was returning to rid the world of unrighteousness and only those who placed their faith in Christ would be saved (Rom 1:1-6; Rom 2:6-16; 2 Cor 5:10). Furthermore, he taught that the dead would be resurrected at the return of Jesus. His message was not well received by Jews, so he eventually stopped going to Jews and focused solely on Gentiles.
Paul believed Yahweh had brought a partial hardening upon Israel until the fullness of the nations/Gentiles* accepted Jesus as the Jewish Messiah who would soon be returning from heaven to rule over all nations (Rom 11:7-10, 25).
Paul taught that believing Gentiles were grafted in to the new covenant blessings. They would be saved from destruction and would experience the universal peace that would characterize Christ’s reign (Col 1:22-23). He believed the inclusion of Gentiles would make Jews jealous so they would become followers of Jesus Christ once Yahweh removed the hardening (Rom 10:19; 11:11, 14). Furthermore, he believed it was Yahweh’s plan from the beginning to save all Israel by including Gentiles in his salvific plan (Rom 11:25-27).
Although Paul expected to be alive when Jesus returned from heaven (1 Thess 4:15-17; 1 Cor 15:51-52), he was killed in 64 or 67 AD. A few years later, Jerusalem was destroyed by the Romans in the First Jewish–Roman War.
The other apostles continued to encourage members of the Way to remain faithful since Jesus had promised to return while some of them were still alive (Matt 16:28; Mark 9:1; Luke 9:27), but as the years dragged on, more and more Jews abandoned their belief that Jesus was the Messiah.
In the Gospel of John, written near the close of the first century, the author still speaks of Jesus’ imminent return but appears to have given up on the prophecy that Jesus will return to earth to reign in Israel. Instead, he writes of the present reality of the kingdom with the reign of Jesus beginning when he was lifted up on the cross and continuing from heaven.
By the end of the second century, Gentile “Christians” (the new name for members of the Way) far outnumbered Jewish Christians. And it was during the second century that Gentile Christians, who were now in leadership positions, began reshaping Christianity by pulling it out of Judaism and purging it of its Jewishness.
Of course, the fourth century saw the trinitarian doctrine established as a Church creed. This doctrine, which was developed from the second through the fourth centuries, was a source of conflict between Jews and Christians throughout this period. (Although this doctrine was developed by Gentiles, it was built upon the Luke and Matthew birth accounts, the Jewish concept of personified Wisdom, the notions related to Logos expressed by Philo and the writer of the fourth Gospel, and the eschatological relationship between last things and first things.)
At the end of the fourth century, Augustine created a theological framework for Christianity that no longer revolved around Yahweh’s covenant with Israel. He also rejected the apocalyptic reign of the Messiah from the new Jerusalem and argued, using the Gospel of John, that the kingdom of God should be understood figuratively and allegorically rather than literally.
In the 16th century, Luther and the reformers continued to build on Augustine’s ideas, which continued to reshape Christianity into a religion that taught the Gentile Church had replaced Jews as God’s chosen. This religion focused on universal sin and personal salvation for all who believed; i.e., people could avoid hell and go to heaven when they died.
Later, in the 1800s, John Nelson Darby came up with the idea of the saints being raptured from the earth prior to a period of great earthly tribulation, an idea completely foreign to the beliefs of Jesus and his first-century followers. This Pre-tribulation rapture theology was popularized in the United States in the early 20th century by the wide circulation of the Scofield Reference Bible and is still a popular doctrine among many Protestant denominations.
As you can see, modern Christianity has very little in common with the Way. On the other hand, one could argue that in the 21st century, modern Christianity is the more useful of the two.

*The phrase “fullness of the Gentiles” may have referred to the ten northern tribes of ancient Israel. Alternatively, “fullness of the Gentiles” may have referred to Gentiles who represented the nations Jewish prophets said would forsake their gods to worship Yahweh and give tribute to Israel (Ps 86:9; Isa 14:2; Amos 9:11-15; Zech 8:22-23, 14:9).
