<p>6:71 <i>Now he spoke of Judas, the son of Simon Iscariot; for he was the one of those twelve who would betray him</i>- Clearly the term &quot;devil&quot; doesn't refer to an Angelic being who fell off the 99th floor in Eden. The term is here applied to Judas, just as &quot;satan&quot; is to Peter. Perhaps this is another of the points of similarity between Peter and Judas, who in essence did the same thing in denying the Lord; and yet Peter's core faith triumphed and he repented, whereas Judas could not believe in the Lord's grace as Peter did.</p>
