Gospel According to St Luke: Jesus said:
25. And there shall be signs in the sun, and in the moon, and in the stars; and upon the earth distress of nations, with perplexity; the sea and the waves roaring;
26. Men's hearts failing them for fear, and for looking after those things which are coming on the earth: for the powers of heaven shall be shaken.
27. And then shall they see the Son of man coming in a cloud with power and great glory.
ST BEDE; The events which were to follow the fulfillment of the times of the Gentiles He explains in regular order, saying, There shall be signs in the sun, and in the moon, and in the stars.
ST AMBROSE; All which signs are more clearly described in Matthew, Then shall the sun be darkened, and the moon shall not give her light, and the stars shall fall from heaven.
EUSEB. For at that time when the end of this perishing life shall be accomplished, and, as the Apostle says, The fashion of this world passes away, then shall succeed a new world in which instead of sensible light, Christ Himself shall shine as a sunbeam, and as the King of the new world, and so mighty and glorious will be His light, that the sun which now dazzles so brightly, and the moon and all the stars, shall be hidden by the coming of a far greater light.
ST CHRYS For as in this world the moon and the stars are soon dimmed by the rising of the sun, so at the glorious appearance of Christ shall the sun become dark, and the moon not shed her ray, and the stars shall fall from heaven, stripped of their former attire, that they may put on the robe of a better light.
EUSEB. What things shall befall the world after the darkening of the orbs of light, and whence shall arise the straitening of nations, He next explains as follows, And of the earth distress of nations, by reason of the confusion of the roaring of the sea. Wherein He seems to teach, that the beginning of the universal change will be owing to the failing of the watery substance. For this being first absorbed or congealed, so that no longer is heard the roaring of the sea, nor do the waves reach the shore because of the exceeding drought, the other parts of the world, ceasing to obtain the usual vapor which came forth from the watery matter, shall undergo a revolution. Accordingly since the appearance of Christ must put down the prodigies which resist God, namely, those of Antichrist, the beginnings of wrath shall take their rise from droughts, such as that neither storm nor roaring of the sea be any more heard.
And this event shall be succeeded by the distress of the men who survive; as it follows, Men's hearts being dried up for fear, and looking after those things which shall come upon the whole world. But the things that shall then come upon the world He proceeds to declare, adding, For the powers of heaven shall be shaken.
THEOPHYL. Or else, When the higher world shall be changed, then also the lower elements shall suffer loss; whence it follows, And on the earth distress of nations, &c. As if He said, the sea shall roar terribly, and its shores shall be shaken with the tempest, so that of the people and nations of the earth there shall be distress, that is, a universal misery, so that they shall pine away from fear and expectation of the evils which are coming upon the world.
ST AUG. But you will say, your punishment compels you to confess that the end is now approaching, seeing the fulfillment of that which was foretold. For it is certain there is no country, no place in our time, which is not affected or troubled. But if those evils which mankind now suffer are sure signs that our Lord is now about to come, what means that which the Apostle says, For when they shall say peace and safety. Let us see then if it be not perhaps better to understand the words of prophecy to be not so fulfilled, but rather that they will come to pass when the tribulation of the whole world shall be such that it shall belong to the Church, which shall be troubled by the whole world, not to those who shall trouble it. For they are those who shall say, Peace and safety. But now these evils which are counted the greatest and most immoderate, we see to be common to both the kingdoms of Christ and the Devil. For the good and the evil are alike afflicted with them, and among these great evils is the yet universal resort to licentious feasts. Is not this the being dried up from fear, or rather the being burnt up from lust?
But not only shall men be tossed about when the world shall be changed, but angels even shall stand amazed at the terrible revolutions of the universe. Hence it follows, And the powers of heaven shall be shaken.
ST GREG. For whom does He call the powers of heaven, but the angels, dominions, principalities, and powers? which at the coming of the strict Judge shall then appear visibly to our eyes, that they may strictly exact judgment of us, seeing that now our invisible Creator patiently bears with us.
EUSEB. When also the Son of God shall come in glory, and shall crush the proud empire of the son of sin, the angels of heaven attending Him, the doors of heaven which have been shut from the foundation of the world shall be opened, that the things that are on high may be witnessed.
ST CHRYS. Or the heavenly powers shall be shaken, although themselves know it not. For when they see the innumerable multitudes condemned, they shall not stand there without trembling.
ST BEDE; Thus it is said in Job, the pillars of heaven tremble and are afraid at his reproof. What then do the boards do, when the pillars tremble? what does the shrub of the desert suffer, when the cedar of Paradise is shaken?
EUSEB. Or the powers of heaven are those which preside over the sensible parts of the universe, which indeed shall then be shaken that they may attain to a better state. For they shall be discharged from the ministry with which they serve God toward the sensible bodies in their perishing condition.
ST AUG. But that the Lord may not seem to have foretold as extraordinary those things concerning His second coming, which were wont to happen to this world even before His first coming, and that we may not be laughed at by those who have read more and greater events than these in the history of nations, I think what has been said may be better understood to apply to the Church. For the Church is the sun, the moon, and the stars, to whom it was said, Fair as the moon, elect as the sun. And she will then not be seen for the unbounded rage of the persecutors.
ST AMBROSE; While many also fall away from religion, clear faith will be obscured by the cloud of unbelief, for to me that Sun of righteousness is either diminished or increased according to my faith; and as the moon in its monthly wanings, or when it is opposite the sun by the interposition of the earth, suffers eclipse, so also the holy Church when the sins of the flesh oppose the heavenly light, cannot borrow the brightness of divine light from Christ's rays. For in persecutions, the love of this world generally shuts out the light of the divine Sun; the stars also fall, that is, men who shine in glory fall when the bitterness of persecution waxes sharp and prevails. And this must be until the multitude of the Church be gathered in, for thus are the good tried and the weak made manifest.
ST AUG. But in the words, And upon the earth distress of nations, He would understand by nations, not those which shall be blessed in the seed of Abraham, but those which shall stand on the left hand.
ST AMBROSE; So severe then will be the manifold fires of our souls, that with consciences depraved through the multitude of crimes, by reason of our fear of the coming judgment, the dew of the sacred fountain will be dried upon us. But as the Lord's coming is looked for, in order that His presence may dwell in the whole circle of mankind or the world, which now dwells in each individual who has embraced Christ with his whole heart, so the powers of heaven shall at our Lord's coming obtain an increase of grace, and shall be moved by the fullness of the Divine nature more closely infusing itself. There are also heavenly powers which proclaim the glory of God, which shall be stirred by a fuller infusion of Christ, that they may see Christ.
ST AUG. Or the powers of heaven shall be stirred, because when the ungodly persecute, some of the most stout-hearted believers shall be troubled.
THEOPHYL. It follows, And then shall they see the Son of man coming in the clouds. Both the believers and unbelievers shall see Him, for He Himself as well as His cross shall glisten brighter than the sun, and so shall be observed of all.
ST AUG. But the words, coming in the clouds, may be taken in two ways. Either coming in His Church as it were in a cloud, as He now ceases not to come. But then it shall be with great power and majesty, for far greater will His power and might appear to His saints, to whom He will give great virtue, that they may not be overcome in such a fearful persecution. Or in His body in which He sits at His Father's right hand He must rightly be supposed to come, and not only in His body, but also in a cloud, for He will come even as He went away, And a cloud received him out of their sight.
ST CHRYS. For God ever appears in a cloud, according to the Psalms, clouds and darkness are round about him. Therefore shall the Son of man come in the clouds as God, and the Lord, not secretly, but in glory worthy of God. Therefore He adds, with great power and majesty.
ST CYRIL; Great must be understood in like manner. For His first appearance He made in our weakness and lowliness, the second He shall celebrate in all His own power.
ST GREG. For in power and majesty will men see Him, whom in lowly stations they refused to hear, that so much the more acutely they may feel His power, as they are now the less willing to bow the necks of their hearts to His sufferings.
