The gospel of Judas Iscariot is filled with gnostic thinking. Gnosticism can be simply explained that the people on top believe that they have special knowledge that they know and you don’t, it’s something holier than you, something that you will never attain.
Gnosticism is very off-message for what Jesus usually stands for, “Anyone with ears to hear should listen and understand.”
Examples of this can be found throughout the text. Jesus repeatedly tells the disciples that nobody from their generation is strong and holy and that no angels will watch over them. Jesus also talks of predestination, that it is no use for them to sacrifice upon the altar, for their stars and angels have already decided.
Jesus also seems kind of condescending in this text, something the exact opposite of the kind man he is usually portrayed as. He shuts down the disciples questions, telling them to stop struggling with him, for everything has already been decided. In addition, when Judas approaches him once more, he laughs and asks, “You thirteenth spirit, why do you try so hard? But speak up, and I shall bear with you.”
Basically, the general feel of the text is to give Judas a reason to betray Jesus, instead of it simply being out of his greed, or being possessed by Satan.
An example of this can be found in the same passage as the previous. After Jesus said that he will bear with him, Judas confides in him that he had a vision where the other twelve disciples were persecuting him, but that he followed Jesus to a great house, beyond his comprehension, with great people surrounding it, and and he asked Jesus if he could take him (Judas) in with him.
Jesus said that his stars have led him astray (meaning, that’s silly of you to even think), and that no mortal person was worthy enough to enter the house, as they would never be holy enough.
