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.
Judaism's view of Jesus
Judaism's idea of the messiah differs substantially from the Christian idea of the Messiah. In Orthodox Judaism, the messiah's task is to bring in the Messianic Age, a one-time event, and a presumed messiah who is killed before completing the task (i.e. compelling all of Israel to walk in the way of Torah, repairing the breaches in observance, fighting the wars of God, building the Temple in its place, gathering in the dispersed exiles of Israel) is not the messiah. Maimonides states, 
Jews believe that the messiah will fulfill the messianic prophecies of the prophets Isaiah and Ezekiel. According to Isaiah, the messiah will be a paternal descendant of King David. He is expected to return the Jews to their homeland and rebuild the Temple, reign as King, and usher in an era of peace and understanding where "the knowledge of God" fills the earth, leading the nations to "end up recognizing the wrongs they did Israel". Ezekiel states the messiah will redeem the Jews.
