Barnabas' real name was Joseph, a Levite from Cyprus. Barnabas was a member of the Jerusalem church, an important mother church. Barnabas was an influential figure who also sold his farm and brought the proceeds to the apostles for distribution among the Jerusalem church.Barnabas was also the only person who welcomed Paul's conversion and invited him to join the church. Paul's arrival was initially met with resistance from the congregation, given his violent actions against the Christians of the time. But Barnabas convinced the other members of the congregation that Paul had changed, until finally Paul was accepted. Over time Barnabas and Paul became close. They became partners in evangelism with the same vision: that the gospel should not be confined to the Jews. The gospel must be shared with all people, so that the good news can reach all nations. Barnabas and Paul bore witness that Christ embraces all nations. After the council in Jerusalem, Barnabas and Paul chose different paths to spread the gospel, simply because of different opinions about who to invite. Barnabas continued his journey to Cyprus, where he became a highly respected figure as a pioneer of Christianity in Cyprus.

Although little is written about Barnabas, even after Acts chapter 15, he never appears again in New Testament stories. Yet Barnabas is actually a very important figure. According to the records, Barnabas was a good man, full of holy spirit, and had a firm faith. So what about the writings that are claimed to be those of Barnabas?

In chronological order, the oldest writing is the Epistle of Barnabas. Written in the mid-3rd century, it was included in the Sinaitic codex. However, it was not included in the canon. There is also the “Acts of Barnabas”, written by someone named John Mark. This text contains the ministry journey of Barnabas and John Mark to various regions with all the dynamics of service against idolaters as far as Salamis. The Acts of Barnabas is thought to have originated in the 5th century, so it is natural that it is less considered to be included in the canon because of the age of the writing which is considered young. The most famous and controversial gospel among Christians today is the Gospel of Barnabas. The original text of the Gospel of Barnabas has not been found, but the parchments found show that the Gospel of Barnabas dates back to the 18th century, a writing that was born after the vulgata. A writing that is too recent.

What is its content? What were the considerations that kept it out of the canon?"
