Judas Iscariot
Judas Iscariot (died AD) was a disciple and one of the original Twelve Disciples of Jesus Christ. According to all four canonical gospels, Judas betrayed Jesus to the Sanhedrin in the Garden of Gethsemane by kissing him and addressing him as "Rabbi" to reveal his identity to the crowd who had come to arrest him. His name is often used synonymously with betrayal or treason. Judas's epithet "Iscariot" most likely means he came from the village of Kerioth, but this explanation is not universally accepted and many other possibilities have been suggested.
Judas Iscariot
Judas has been a figure of great interest to esoteric groups, such as many Gnostic sects. Irenaeus records the beliefs of one Gnostic sect, the Cainites, who believed that Judas was an instrument of the Sophia, Divine Wisdom, thus earning the hatred of the Demiurge. His betrayal of Jesus thus was a victory over the materialist world. The Cainites later split into two groups, disagreeing over the ultimate significance of Jesus in their cosmology.
