JUDAS’S BETRAYAL OF CHRIST FORETOLD.
And if we must make a statement regarding Judas that may overwhelm our opponents with shame, we would say that, in the book of Psalms, the whole of Psalm 108 [LXX] contains a prophecy about Judas, the beginning of which is this: O God, whom I praise, do not remain silent; for the mouths of the sinner and the mouth of the deceitful man are opened against me. And it is predicted in this psalm both that Judas separated himself from the number of the apostles on account of his sins and that another was selected in his place; and this is shown by the words and let another man take his position. But now suppose that he had been betrayed by one of his disciples, who was possessed by a worse spirit than Judas and who had completely poured out, as it were, all the words that he had heard from Jesus, what would this contribute to an accusation against Jesus or the Christian religion? And how will this demonstrate its doctrine to be false? We have replied in the preceding chapter to the statements that follow this, showing that Jesus was not taken prisoner when attempting to flee but that he gave himself up voluntarily for the sake of us all. Therefore it follows, that even if he were bound, he was bound agreeably to his own will, thus teaching us the lesson that we should undertake similar things for the sake of religion in a spirit of willingness.
