Luke 17:25

When our Lord said, The kingdom of God is within you, He would fain prepare His disciples for suffering, that being made strong they might be able to enter the kingdom of God; He therefore foretells to them, that before His coming from heaven at the end of the world, persecution will break out upon them. Hence it follows, And he said to the disciples, The days will come, &c. meaning that so terrible will be the persecution, that they would desire to see one of His days, that is, of that time when they yet walked with Christ. Truly the Jews ofttimes beset Christ with reproaches and insults, and sought to stone Him, and ofttimes would have hurled Him down film the mountain; but even these seem to be looked upon as slight in comparison of greater evils that are to come.

For their life was then without trouble, for Christ took care of them and protected them. But the time was coming when Christ should be taken away, and they should be exposed to perils, being brought before kings and princes, and then they should long for the first time and its tranquillity.

Or, by the day of Christ He signifies His kingdom, which we hope will come, and He lightly says, one day, because there shall no darkness disturb the glory of that blessed time. It is right then to long for the day of Christ, yet from the earnestness of our longing, let us not vision to ourselves as though the day were at hand. Hence it follows, And they shall say to you, Lo here! and, Lo there!

As if he said, If at the coming of Antichrist, his fame shall be spread abroad, as though Christ had appeared, go not out, nor follow him. For it cannot be that He who was once seen on earth, shall any more dwell in the corners of the earth. It will therefore be he of whom we speak, not the true Christ. For this is the clear sign of the second coming of our Savior, that suddenly the luster of His coming shall fill the whole world; and so it follows, For as the lightning that lightens, &c. For He will not appear walking upon the earth, as any common man, but will illuminate our whole universe, manifesting to all men the radiance of His divinity.

And he well says, that lightens out of the one part under heaven, because the judgment will be given under the heaven, that is, in the midst of the air, as the Apostle says, We shall be caught up together with them in the clouds. But if the Lord shall appear at the Judgment like lightning, then shall no one remain hidden in the deep of his heart, for the very brightness of the Judge pierces through him; we may also take this answer of our Lord to refer to His coming, whereby He comes daily into His Church. For ofttimes have heretics so vexed the Church, by saying that the faith of Christ stands in their own dogma, that the faithful in those times longed that the Lord would if it were possible even for one day return to the earth, and Himself make known what was the true faith. And you shall not see it, because it need not that the Lord should again testify by a bodily presence that which has been spiritually declared by the light of the Gospel, once scattered and diffused throughout the whole world.

Now His disciples supposed that He would go to Jerusalem, and would at once make a manifestation of the kingdom of God. To rid them therefore of this belief, He informs them that it became Him first to suffer the Life-giving Passion, then to ascend to the Father and shine forth from above, that He might judge the world in righteousness. Hence He adds, But first must he suffer many things, and be rejected of this generation.

He means the generation not only of the Jews, but also of all wicked men, by whom even now in His own body, that is, His Church, the Son of man suffers many things, and is rejected. But while He spoke many things of His coming in glory, He inserts something also concerning His Passion, that when men saw Him dying, whom they had heard would be glorified, they might both soothe their sorrow for His sufferings by the hope of the promised glory, and at the same time prepare themselves, if they love the glories of His kingdom, to fool; without alarm upon the horrors of death.

Then, turning to His disciples, He says: “Woe unto him through whom offences come! It were better for him if he had not been born, or if a millstone were hanged about his neck and he were cast into the sea, than that he should offend one of these little ones,” that is, one of His disciples. Judge, then, what the sort of punishment is which He so severely threatens. For it is no stranger who is to avenge the offence done to His disciples. Recognise also in Him the Judge, and one too, who expresses Himself on the safety of His followers with the same tenderness as that which the Creator long ago exhibited: “He that toucheth you toucheth the apple of my eye.” Such identity of care proceeds from one and the same Being. A trespassing brother He will have rebuked. …

“The world,” he says, “knew Him not”; but they of whom the world was not worthy knew Him. And having spoken of those who knew Him not, he in a short time puts the cause of their ignorance; for he does not absolutely say, that no one knew Him, but that “the world knew him not”; that is, those persons who are as it were nailed to the world alone, and who mind the things of the world. For so Christ was wont to call them; as when He says, “O Holy Father, the world hath not known Thee.” ( c. xvii. 25 .) The world then was ignorant, not only of Him, but also of His Father, as we have said; for nothing so darkens the mind as to be closely attached to present things.
