Contradiction with John 6:70
Jesus indicates that one of the disciples is a devil, suggesting foreknowledge of betrayal which complements rather than directly contradicts Mark 14:18, but highlights differing emphasis in the narrative.
John 6:70: Jesus answered them, Have not I chosen you twelve, and one of you is a devil?
Contradiction with John 13:27
Jesus tells Judas to proceed with his betrayal quickly; here, Jesus' explicit direction could be seen as contrasting with the implied inevitability in Mark 14:18.
John 13:27: And after the sop Satan entered into him. Then said Jesus unto him, That thou doest, do quickly.
Contradiction with Luke 22:3
States that Satan entered Judas, suggesting an external influence rather than Judas acting independently, which could be seen as a different cause for the betrayal described in Mark 14:18.
Luke 22:3: Then entered Satan into Judas surnamed Iscariot, being of the number of the twelve.
Contradiction with Matthew 26:24
Suggests woe to the betrayer, indicating a moral judgment that might contrast with the simple foretelling in Mark 14:18.
Matthew 26:24: The Son of man goeth as it is written of him: but woe unto that man by whom the Son of man is betrayed! it had been good for that man if he had not been born.
