Now, while Paul was carrying the gospel to the Gentiles, others were focused on the Jewish diaspora. Moreover, like Paul, they sometimes employed literate believers to compose letters in the then universal language of Greek to reach those scattered believers.
The anonymous epistle to the Hebrews was one of them. The letter focused on interpreting the Hebrew Bible through the Christ event and comparing the Old Covenant to the New Covenant. It opened with a declaration of Christ's role as God's representative and his superiority to the angelic realm (Hebrews 1). The author then proceeded to describe precisely how Christ brought salvation to humankind, his superiority to Moses, and how he represented the ultimate Sabbath for believers (Hebrews 2-4:13). The epistle also described Christ's role as the High Priest of the New Covenant (Hebrews 4:14-8:13). Next, the author described how Christ fulfilled the sacrificial/ritualistic system of Torah (Hebrews 9-10). Finally, the letter concluded with an explanation of the central role which faith had played in the old system and would continue to play in the new one (Hebrews 11-12).
In similar fashion, James addressed his epistle "To the twelve tribes in the Dispersion." (James 1:1) He focused on Jewish Christians demonstrating their faith in Christ's sacrifice by admonishing them to be doers of God's word, not just hearers (James 1-2). Even so, James reiterated Christ's assertion that the central responsibility of his disciples was to fulfill the Law of Love (James 2:8-13). James went on to encourage Jewish Christians to tame their speech (James 3:1-12). He also reminded his audience about the dangers inherent to giving into the passions which rage within all humans (James 4:1-12). He went on to conclude his remarks with an admonishment to remain faithful to Christ and each other (James 5).
Likewise, Peter addressed his first epistle "To those who are elect exiles of the Dispersion in Pontus, Galatia, Cappadocia, Asia, and Bithynia." (I Peter 1:1) Peter opened by reminding his Jewish audience that they had been sprinkled with the blood of Jesus Christ (I Peter 1:2). He also went on to remind them that their hope was centered on the fact that God had resurrected Jesus Christ from the grave (I Peter 1:3-9). Like James, Peter reminded his audience that God had called them to live holy lives (I Peter 1:13-25 and 2:1-12). Like James, he also reiterated Christ's teaching about brotherly love and forgiveness (I Peter 3:8-12) He also admonished Jewish believers to follow Christ's example of patience and humility in the face of suffering and persecution (I Peter 3:13-22 and 4:1-19). Finally, Peter closed with an admonishment for the leadership among them to follow the example of the Good Shepherd of service to others (I Peter 5:1-11).
For Jewish Christians, the focus was on Christ's roll in fulfilling the Hebrew Scriptures. As we have already observed, these folks continued to participate in synagogues. Likewise, they persisted in observing the weekly Sabbath, Holy Days, and in observing the laws surrounding clean and unclean. Nevertheless, like their Gentile brethren, their focus was on Jesus Christ's sacrifice for them, and the fact that God had resurrected him from death. In short, they were Christians who continued to live their lives as cultural Jews.
We must also remember that MOST of them had accepted the Council of Jerusalem's decision regarding a Gentile believer's obligation to Torah (that they were NOT required to observe the tenets of God's covenant with Israel). Even so, there continued to be a small but vocal group of Jewish believers who insisted that everyone (including Gentile converts) was obligated to obey the commandments of Torah. Moreover, many non-believing Jews were, by this time, openly hostile to Christian teachings.
As a Jew and an apostle of Jesus Christ, Paul had experienced the full range of Jewish beliefs and practices. He had also been warned about what he would face in Jerusalem. Hence, he must have been aware that an appearance at the Temple would be dangerous. Indeed, as soon as some of the Asian Jews spotted Paul there, they began stirring up the crowd against him. They claimed that Paul was anti-Jewish, and that he had preached against Torah and the Temple. They also accused him of defiling the Temple by bringing Gentiles into it. (Acts 21:27-29) As a consequence, a large group of these Jews seized Paul and dragged him outside of the Temple. Although the mob clearly intended to kill Paul, the commander of a Roman regiment of soldiers intervened and took him into protective custody. (Acts 21:30-36)
When Paul's safety had finally been secured, he asked the commander for permission to address the mob. The commander gave his assent, and Paul was allowed to speak. He addressed them in Hebrew and briefly recounted his own background in the Jewish religion and in persecuting Christians. (Acts 22:1-21) The mob, however, began screaming at him when he told them that God had sent him to preach to the Gentiles. Thus, the commander intervened again and ordered his soldiers to take Paul inside their headquarters and question him about the riot that he had provoked. Nevertheless, before the soldiers began their interrogation, Paul asked them if it was legal to whip a Roman citizen without a trial. Then a centurion reported what the prisoner had said to the commander, and the interrogation of Paul was immediately suspended. (Acts 22:22-29)
The following day, the commander ordered the Jewish Council to assemble and presented Paul to them for their evaluation of him (Acts 22:20). Paul stood before the Council and declared: "Brothers, I have lived my life before God in all good conscience up to this day." At that, the High Priest ordered those next to Paul to slap his face. "God is going to strike you, you whitewashed wall! Are you sitting to judge me according to the law, and yet contrary to the law you order me to be struck?" Paul responded. This only served to further inflame the High Priest and his supporters, so Paul apologized for being unintentionally impertinent. (Acts 23:1-5)
Now, Paul realized that the Council was composed of both Pharisees and Sadducees, and he declared to the assembly that he was associated with the beliefs of the Pharisees. "It is with respect to the hope and the resurrection of the dead that I am on trial," he declared. Hearing that, the Pharisees on the Council all said that they couldn't find any fault with what Paul was saying. As a consequence, the Council became embroiled in a heated debate between the two parties, and the tribune again had to intervene to save Paul from the uproar that his remarks had evoked. (Acts 23:6-10)
That evening, the Lord appeared to Paul and said: "Take courage, for as you have testified to the facts about me in Jerusalem, so you must testify also in Rome." (Acts 23:11) Nevertheless, the next day Paul learned of a plot by over forty individuals to murder him, and that they had obtained the cooperation of some of the leading members of the Council in their plans. However, when the tribune heard about the plot, he decided to remove Paul from the Council's reach and thwart the plans of the conspirators. (Acts 23:12-22)
Thus, the commander wrote a letter to Felix, who was then the governor of the province, explaining Paul's circumstances and asking him to intervene in the matter. Toward that end, he ordered a large detachment of Roman soldiers to take Paul to Caesarea and present him to the governor. As a consequence, Felix agreed to hear Paul's case after his accusers had been given the opportunity to also appear at the hearing. (Acts 23:23-35)
Five days later, the High Priest arrived in Caesarea with a small group of elders who were prepared to make their case against Paul. Both sides presented their case to Felix, and the apostle defended both his actions and his beliefs against his accusers. The governor, however, did not want to offend the Jewish religious leadership; so, he decided to keep Paul in prison. Hence, for the next two years Paul remained in a kind of limbo. (Acts 24)
Now, although no one knows the exact date, it was about this time that accounts of Christ's life, death, and resurrection began to be committed to writing. Prior to this, they had been told and retold many times throughout the years since Christ's death and resurrection. Once again, although there is much uncertainty surrounding the process of writing the Synoptic Gospels, a scholarly consensus has rallied around what is known as the Four-Source Hypothesis. Indeed, in Bart Ehrman's The Bible: A Historical and Literary Introduction (Oxford University Press, 2018), we are informed that this is "the view held by the vast majority of critical scholars today."
Ehrman wrote: "The foundation for this hypothesis is that among the three Synoptic Gospels, Mark was the first to be written and was copied, in part, by both Matthew and Luke for many of their stories. This view is sometimes called Markan Priority, that is, Mark was prior to and used by the other two. There are numerous reasons for holding this view." Ehrman went on to list three of the main justifications for holding to this view: 1) the patterns of agreement between them, 2) the sequence in which the stories appear, and 3) the fact that both Matthew and Luke make independent corrections to problematic passages found in Mark. Hence, Mark becomes the principal source for both of the other Gospels. Likewise, there must have been some other source for stories which do NOT appear in Mark but do appear in both Luke and Matthew. Finally, there is some material that is unique to Matthew, and some that is unique to Luke. I trust my readers with the math - that makes FOUR sources in total for the material found in the Gospels of Matthew and Luke. We should also note that there is a widespread consensus that the Gospel of John was composed later than the Synoptic Gospels and was composed independently of those accounts.
To briefly summarize, during this period, we begin to see epistles and written accounts of Christ's story circulating among the various congregations of the Christian Church. To be clear, there was still nothing like the New Testament Canon at the time. Hence, roughly thirty years after Christ's death and resurrection we begin to see some of these writings being shared among SOME of the congregations of the Church! Thus, although the developments which we have heretofore discussed are a very important part of the story of the Church, we must keep in mind that we are only about one-third of our way through that first one-hundred years!
