Apostles
Later in the Gospel narratives the twelve apostles are described as having been commissioned to preach the Gospel to "all the nations", regardless of whether Jew or Gentile. Paul emphasized the important role of the apostles in the church of God when he said that the household of God is "built upon the foundation of apostles and prophets, Christ Jesus himself being the cornerstone".
Although not one of the apostles commissioned during the life of Jesus, Paul, a Jew named Saul of Tarsus, claimed a special commission from the risen Jesus and is considered "the apostle of the Gentiles", for his missions to spread the gospel message after his conversion. In his writings, the epistles to Christian churches throughout the Levant, Paul did not restrict the term "apostle" to the Twelve, and often refers to his mentor Barnabas as an apostle. The restricted usage appears in the Revelation to John.
Names and titles of Jesus in the New Testament
While John's Gospel emphasizes Jesus as the Son of God, the Gospel of Luke depicts him as a prophet above all else, attributing that title to Jesus more often than even Mark. A prophet is not someone who merely preaches, but claims divine revelation through God. In following his hometown rejection episode, Jesus remarks that as a prophet he is not welcome in his own hometown. Elsewhere, in the Jews again doubt that Jesus is a prophet. The view of Jesus as a prophet is used in the concept of threefold office which sees his 3 roles as "Prophet, Priest and King". While during early Christianity there were people claiming to be prophets, there are no records of anyone else claiming to be a prophet during the life of Jesus.
