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.
Gospel of Judas
The Gospel of Judas is a Gnostic gospel whose content consists of conversations between Jesus and Judas Iscariot. It is thought to have been composed in the second century by Gnostic Christians, not by Judas, since it contains late-2nd-century theology. The only copy of it known to exist is a Coptic language text that has been carbon dated to AD 280, plus or minus 60 years. It has been suggested that the text derives from an earlier Greek version. A translation of the text was first published in early 2006 by the National Geographic Society.
