The Kiss of Judas is an ability by Judas Iscariot one of the disciples of Jesus Christ who betrayed him after the Last Supper. This power has the ability to corrupt and taint any divine being be it angel or deity. The kiss itself also symbolizes the ultimate betrayal with one who fashioned you into his disciple and considered you a brother-in-arms.
It was first discovered when Judas identified Jesus to the soldiers by means of a kiss. This is the kiss of Judas, also known (especially in art) as the Betrayal of Christ, which occurs in the Garden of Gethsemane after the Last Supper, and leads directly to the arrest of Jesus by the police force of the Sanhedrin.
Each Gospel describes the role that Judas plays in the Passion. Jesus conducts the Last Supper with his disciples, prays in Gethsemane, and is arrested by soldiers led by Judas. In the Synoptic Gospels beginning with Mark (the earliest Gospel, dating to around 70 C.E.), Judas leads the soldiers and exclaims: “The one I will kiss is the man; arrest him and lead him away under guard” (Mark 14:44). Thus, the earliest Gospel establishes the lasting symbol of the Judas kiss. Matthew also includes the kiss of Judas in the arrest sequence; however, Luke depicts Jesus questioning Judas: “Is it with a kiss that you are betraying the Son of Man?” (Luke 22:48). And John avoids the kiss altogether, focusing instead on the villainy of Judas’s treason.
