The name Judas Iscariot usually provokes a negative response as the disciple who betrayed his Lord to death. It is difficult to think of another person, dead for so long, who is so closely associated with betrayal. In recent times, some commentators have urged a rethink on Judas, arguing that he has been unfairly treated. This book will show that the traditional picture of Judas as a traitor best fits the biblical evidence. It also establishes two other points. Firstly, although Judas was a human being, he had the literary features of an idol. Secondly, the earliest gospel, Mark, clearly establishes his guilt and Matthew and Luke show how uniquely guilty Judas was.
