The twelve Apostles of Jesus Christ.

The Apostles (one sent forth as a messenger) were missionaries among the leaders in the Early Church. Traditionally, the Twelve Apostles include Peter (whom some denominations consider the "Prince of the Apostles"); Andrew, James the Greater, James the Less, John, Philip, Bartholomew, Matthew, Thomas, Thaddeus, Simon, and Judas Iscariot. Judas had been one of the Twelve, but he betrayed Jesus and killed himself. With Judas gone, Matthias became one of the Twelve. In the Synoptic Gospels, Mark names the Twelve, Matthew follows Mark, and Luke substitutes Jude for Mark's Thaddeus. John refers to the Twelve without naming them all, adds the name Nathanael, and uses the term "beloved disciple" (presumably for John).
