The apostle John made reference to the spirit if antichrist which he said was ALREADY in the world at the time of his writing. That antichrist or false christ "in place of Christ" was at that time primarily Gnostics who made up their own version of Christ, one that suited them better the the REAL One. On a side note, this is much along the same line as what Mr Tabor is doing with his work, trying to make Jesus fit what is wanted rather then accepting what He is.

The "gospel" of Judas is part of this anti christ movement. The spirit of antichrist has continued throughout history to this very day. Along the same vein, Judas betrayed Jesus because of his desire to make Christ into something he wanted. Instead Christ delivered everyone that will accept His gift from sin and its consequenses.
