Tertullian — Against Marcion 41

Woe, says He, to that man by whom the Son of man is betrayed! Luke 22:22 Now it is certain that in this woe must be understood the imprecation and threat of an angry and incensed Master, unless Judas was to escape with impunity after so vast a sin . If he were meant to escape with impunity, the woe was an idle word; if not, he was of course to be punished by Him against whom he had committed the sin of treachery.

Now, if He knowingly permitted the man, whom He deliberately elected to be one of His companions, to plunge into so great a crime, you must no longer use an argument against the Creator in Adam's case, which may now recoil on your own God: either that he was ignorant , and had no foresight to hinder the future sinner; or that he was unable to hinder him, even if he was ignorant ; or else that he was unwilling , even if he had the foreknowledge and the ability; and so deserved the stigma of maliciousness, in having permitted the man of his own choice to perish in his sin . I advise you therefore (willingly) to acknowledge the Creator in that god of yours, rather than against your will to be assimilating your excellent god to Him.

For in the case of Peter, too, he gives you proof that he is a jealous God , when he destined the apostle, after his presumptuous protestations of zeal , to a flat denial of him, rather than prevent his fall . The Christ of the prophets was destined, moreover, to be betrayed with a kiss , Luke 22:47-49 for He was the Son indeed of Him who was honoured with the lips by the people. Isaiah 29:13 When led before the council, He is asked whether He is the Christ. Luke 22:66-67 Of what Christ could the Jews have inquired but their own? Why, therefore, did He not, even at that moment, declare to them the rival (Christ)? You reply, In order that He might be able to suffer. In other words, that this most excellent god might plunge men into crime, whom he was still keeping in ignorance . But even if he had told them, he would yet have to suffer.

For he said, If I tell you, you will not believe . Luke 22:67 And refusing to believe , they would have continued to insist on his death. And would he not even more probably still have had to suffer, if had announced himself as sent by the rival god, and as being, therefore, the enemy of the Creator? It was not, then, in order that He might suffer, that He at that critical moment refrained from proclaiming Himself the other Christ , but because they wanted to extort a confession from His mouth, which they did not mean to believe even if He had given it to them, whereas it was their bounden duty to have acknowledged Him in consequence of His works, which were fulfilling their Scriptures. It was thus plainly His course to keep Himself at that moment unrevealed, because a spontaneous recognition was due to Him.
