There are even more indications that point to Paul’s influence in the creation of our Bible. For example, in his letter to the Galatians (chapter 2), he refers to three of his fellow apostles: James, Cephas (Peter), John 1:42), and John.
Two ministries
In Galatians 1 and 2, Paul speaks of his unique ministry. He had received his gospel directly from Jesus Christ (1:12) and had not consulted with flesh and blood (1:16), nor with the other apostles (1:17-19). But despite Paul’s unique ministry, which was separate from the Twelve, there was agreement on the difference in calling.
Galatians 2
9 And when they recognized the grace that had been given to me, James, Cephas, and John, who seemed to be pillars, gave to me and Barnabas the right hands of fellowship, so that we would be for the Gentiles, and they for the circumcision.
Agreement
Here we find an agreement among the apostles regarding the difference in ministry, sealed with a handshake. To Paul was entrusted the gospel of the uncircumcision, and to Peter and the Twelve, that of the circumcision (2:7). Paul had a gospel for the Gentiles, the Twelve a message for the circumcision, the Jewish people.
Similarity in Message
The foundation of these different gospels was the same, as Paul teaches elsewhere: Christ died, was buried, rose again on the third day, and appeared to many witnesses (1 Cor. 15:3-8). This is what both Paul and the Twelve proclaimed (1 Cor. 15:11).
Difference
Much could be said about the difference between the gospel of uncircumcision and the gospel of circumcision, but that would be too far off topic.
In short, the Twelve proclaimed to the Jewish people that if they repented, the Messiah would return from heaven and establish His Kingdom (Acts 3:19-21).
Paul, however, knew that Israel would not repent and that salvation was being sent to the nations through the Jewish people’s failure (Acts 13:46, 28:28).
In Galatians 2:9, Paul names the apostles precisely in the order we find their writings in our Bible. He names them in this order and recorded their writings in this order as well.
