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.
Judas Iscariot
During the 1970s, a Coptic papyrus codex (book) was discovered near Beni Masah, Egypt. It appeared to be a 3rd- or 4th-century-AD copy of a 2nd-century original, relating a series of conversations in which Jesus and Judas interact and discuss the nature of the universe from a Gnostic viewpoint. The discovery was given dramatic international exposure in April 2006 when the US "National Geographic" magazine published a feature article entitled "The Gospel of Judas" with images of the fragile codex and analytical commentary by relevant experts and interested observers (but not a comprehensive translation). The article's introduction stated: "An ancient text lost for 1,700 years says Christ's betrayer was his truest disciple." The article points to some evidence that the original document was extant in the 2nd century: "Around A.D. 180, Irenaeus, Bishop of Lyon in what was then Roman Gaul, wrote a massive treatise called "Against Heresies" [in which he attacked] a 'fictitious history,' which 'they style the Gospel of Judas.'"
