Luke 21:25

For at that time when the end of this perishing life shall be accomplished, and, as the Apostle says, The fashion of this world passeth away, (1 Cor. 7:13.) 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.

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 on 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 vapour 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.

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. 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.

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.

(ad Hes. Ep. 199.) But you will say, your punishment compels you to confess that the end is now approaching, seeing the fulfilment 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 meaneth that which the Apostle says, For when they shall say peace and safety. (1 Thess. 5:3.) 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? (ad Hes. ut sup.) 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. (Cant. 6:10.) And she will then not be seen for the unbounded rage of the persecutors. (ut sup.) 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.
