John 5:29

They that have done good, &c. ... shall proceed, Greek ε̉κποζεύσονταί, i.e., shall go forth, out of their tombs and their graves, towards the Valley of Jehoshaphat, where the universal judgment shall take place.

Christ here sets before the unbelieving Jews His authority to judge, that through fear of it He may make them fear, may make them contrite, and convert them. He did the same at the end of His life, when, being adjured by Caiaphas, the High Priest, to say if He was the Son of God, He answered that He was, and added (Matt. xxvi. 64), "Hereafter shall ye see the Son of Man sitting on the right hand of power, and coming in the clouds of heaven."

There is nothing more terrible, and at the same time more effectual for rousing the minds of men to repentance and leading a holy life than a lively representation of the last judgment. So Christ, when He ascended into heaven, commanded His apostles by the angels to preach his return to judgment (Act 1:11). S. Paul pressed the same thing upon the Areopagites (Act 17:31). For in that judgment shall the destiny of each be finally decided for everlasting happiness or everlasting woe. "In all thy works," therefore, "remember thy last end, and thou wilt never sin" (Ecclus. 7:40). In very deed that fateful day will be the last of this world, and the horizon of eternity, which shall separate the just from the unjust and set them far apart, heaping upon the just utmost felicity, and weighing down the unjust with calamity, and that for ever and ever. Think constantly of this wonderful difference, be zealous for holiness, live for eternity. Ver.30. I cannot, &c. Christ shows that His judgment, by which, as man, He will judge all men, will be a last judgment, for his reason that He cannot either judge or will any other thing than that which the Father judges and wills. For He, in that He is God, has the very same judgment, the very self-same Divine mind and will that the Father has. But in that He is man, He is wholly governed by the Divinity and the indwelling Word, so that He can neither judge nor will anything but that which the Godhead judges and wills. So S. Augustine.

As I hear, so I judge : always, and especially in the judgment day. I hear, i.e., I know, I understand. As S. Chrysostom says, "By hearing nothing else is meant than that nothing else is possible but the Father's judgment. I so judge as if the Father Himself were judge."

Because I seek not Mine own will, i.e., Mine own alone, or diverse from the Father's will, for I have no such will, but the will of Him that sent Me : for My Divine will is identical with the Father's, and My human will is wholly conformable to the Divine will. As S. Augustine says, "not that He has no will of His own in judging, but because His will is not so His own as to be diverse from the Father's will." He gives the reason. priori why His future judgment should be just, because, indeed, His will is altogether subject and conformed to the Divine will, because it subsists in the Divine Person of the Word, and is ruled by it. For the will bends and rules the intellect and its judgment in whatever direction it pleases.
