John 12:31

Now is the judgment of this world, &c. Judgment here signifies condemnation, the condemnation of the Jews for condemning Me to death. So SS. Chrysostom, Theophylact, and Euthymius. But others understand it to mean judgment in favour of the innocent. It means, in this sense, the time is at hand for the deliverance of the world from the tyranny of Satan. For my death is at hand, by which this deliverance will be effected, and Satan will be cast out of the hearts of the faithful. Rupertus acutely observes, "Two worlds are here spoken of, one the enemy of God, the other reconciled to Him the one lost, the other saved." He founds this distinction on the absence or the presence of the article [but this does not appear in the Greek]. But what then is the judgment of this world, and the casting out of the prince of this world? Surely the coming Passion of Him who is speaking: for that is the judgment of this world, its salvation indeed, as separating from the reprobate the whole body of the elect from the beginning of the world to the hour of His Passion: and the casting out of the prince of this world, holding sway over the lovers of the world, is the reconciliation of the elect Gentiles. "Christ therefore here signifies (1) that He would by His death free the world (that is the Gentiles who would believe in Him) from sin and the devil; (2) that He would drive out the devil from the hearts of the faithful, and also from the temples, that the true God might be worshipped therein; (3) that He would deprive the devil of the power he had heretofore exercised in tempting men, and would also bestow all-powerful grace, by which, if they willed, they would be able to resist temptation; (4) Christ cast out many devils from the bodies of men, and consigned them to hell. So Prosper (in Dem. Temp.); and see Luke 8:31. S. Augustine writes, "He foresaw that after His Passion and glorification many people throughout the whole world would believe on Him, out of whose hearts the devil is cast when they renounce him by their faith. He was also cast out of the hearts of righteous men of old. But it is said here that he will be cast out, because that which then took place in a very few cases, would hereafter take place in many and great multitudes. He is cast out, but yet ceases not to tempt. But it is one thing to rule within, and another to assail from without." S. Chrysostom in like manner says, "As if a man who assaults his debtors and casts them into prison, and with like madness throws another into prison, who owes him nothing at all, will have to pay the penalty for the wrongs he has done; so will the devil pay the penalty for the wrongs he has done us, by his bold, assaults against Christ."

Just as He Himself says, Luke 11:21.

Christ, therefore, knowing that the Gentiles longed to see Him, was grieved that the whole world was overwhelmed with heathenism, and therefore wishes His death to be hastened, in order that He might obtain for them faith and grace from God, and might send His apostles to convert them to God. And in like manner S. Gregory greatly desired the conversion of the Angles. [This Cornelius tells at length]:
