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.
Criticism of Jesus
Judaism also holds that Jesus couldn't be the Jewish Messiah, arguing that he had not fulfilled any of the Messianic prophecies foretold in the Tanakh, nor did he embody the personal qualifications of the Messiah foretold by the Prophets. According to Jewish tradition, there were no more prophets after Malachi, who lived centuries before Jesus and delivered his prophecies about 420 BCE. Thus Judaism is critical of Jesus' own claims and allusions about his alleged messiahship and his identification as the "son of God", as presented in the New Testament, and considers Jesus to be just one of many individuals who claimed to be the Messiah, but didn't fulfill any of the Messianic prophecies; therefore, they were all impostors.
