Muslims are using liberal scholars arguments to try and cast doubt upon the apostle Paul and his being an apostle of Jesus Al Masih. This video, put together by Keith Thompson of Reformed Apologetics Ministries, shows the historical case for the apostle Paul against Muslim arguments. Keith also writes articles for answering-islam.org.
1. The historical evidence that shows Paul was an apostle, was approved by the 12 disciples of Jesus (without Judas Ischariot, but Matthias had replaced him – see Acts chapter 1); and that they taught the same message. Paul saw Jesus in His resurrection body and was specially called by Christ. (see Acts 9, 22, 26, Acts 15 – agreement with James and Peter; Galatians chapters 1-2, 1 Corinthians 15:1-9).
2. Part 2 shows the problems with trying to use the Ebionites as somehow a “proto-Muslim” group. See also here where I wrote an earlier article that includes refutations of how Muslims try and make the Ebionites some kind of early form of Muslims.
3. Part 3 gives quotes from early Islamic sources and commentators (Al Qurtabi, Al Tabari) that shows that early Muslims understood that Paul was a follower of Jesus and was martyred in Rome along with the apostle Peter. The way they wrote, they had no understanding of him preaching a different message that Peter, John, James, and the rest of the 12 disciples of Jesus. Obviously Judas is not included in the twelve. Matthias was chosen by the disciples to replace Judas. See Acts chapter 1. Many believe that was a human decision, and that God’s miraculous choice was Saul of Tarsus, who was also called “Paul”.
Part 5. Damaging heresies of the Ebionites (Shows that Muslims should not use them, because there are many contradictions of the Ebionites with Islam.)
