Matthew 24:29

One will say, As at the breaking out of great conflagrations, great darkness is at the first caused by the smoke, so when the world shall be consumed by fire, which shall be kindled, even the great luminaries shall be darkened; and when the light of the stars is decayed, the rest of their substance, incapable of exaltation, shall fall from heaven into what it was, when it was first raised aloft by the light. When this shall have taken place, it follows that the rational heavenly powers shall suffer dismay and derangement, and shall be suspended from their functions. Others will think otherwise, that as the light of a lamp dies away by degrees, so when the supply of the heavenly luminaries shall fail, the sun shall be darkened, and the moon and the light of the stars shall grow dim, and that which in their composition is earthy shall fall from heaven. But how can it be said of the sun that its light shall be darkened, when Esaias the Prophet (Is. 30:26.) declares, that in the end of the world, there shall be light proceeding forth from the sun? And of the moon he declares that it shall be as the sun. But concerning the stars, there are some that endeavour to convince us that all, or many of them, are larger than the whole earth. How then shall they fall from heaven, when this earth would not be large enough to contain them? But as, at the dispensation of the Cross, the sun was eclipsed, and darkness was spread over the earth; so when the sign of the Son of Man appears in heaven, the light of the sun, moon, and stars, shall fail, as though waning before the might of that sign. This we understand to be the sign of the cross, that the Jews may see, as Zacharias and John speak, Him whom they have pierced, (Zech. 12:10. John 19:37.) and the sign of victory. Morally, one may say that the sun, which shall be darkened, is the Devil, who shall be convicted in the end of the world, that whereas he is darkness, he has feigned himself to be the sun; the moon, which seems to receive its light from this sun, is the Church of the wicked, which professes to have and to give light, but then convicted with its sinful dogmas, shall lose its brightness; and all those who, either by false teaching, or false virtues, promised truth to men, but led them astray by lies, these are fitly called stars falling from, so to say, their own heaven, where they were raised on high, exalting themselves against the knowledge of God. For illustration of this discourse, we may apply that place in Proverbs, which says, The light of the just is unquenchable, but the light of the wicked shall be quenched. (Prov. 4:18) Then the brightness of God shall appear in every one who has borne the image of the heavenly; and they of heaven shall rejoice, but they of earth shall lament.

The darkening of the sun, the failing of the moon, and the fall of the stars, indicate the glories of His coming.

Then He tells of fearful prodigies. What are these prodigies? "Immediately after the tribulation of those days," saith He, "the sun shall be darkened." Of the tribulation of what days doth He speak? Of those of Antichrist and of the false prophets? For there shall be great tribulation, there being so many deceivers. But it is not protracted to a length of time. For if the Jewish war was shortened for the elect's sake, much more shall this temptation be limited for these same's sake. Therefore, He said not, "after the tribulation," but Immediately "after the tribulation of those days shall the sun be darkened," for almost at the same time all things come to pass. For the false prophets and false Christs shall come and cause confusion, and immediately He Himself will be here. Because no small turmoil is then to prevail over the world. But how doth He come? The very creation being then transfigured, for "the sun shall be darkened," not destroyed, but overcome by the light of His presence; and the stars shall fall, for what shall be the need of them thenceforth, there being no night? and "the powers of Heaven shall be shaken," and in all likelihood, seeing so great a change come to pass. For if when the stars were made, they trembled and marvelled ("for when the stars were made, all angels," it is said, "praised Me with a loud voice"); much more seeing all things in course of change, and their fellow servants giving account, and the whole world standing by that awful judgment-seat, and those who have lived from Adam unto His coming, having an account demanded of them of all that they did, how shall they but tremble, and be shaken? "Then shall appear the sign of the Son of Man in Heaven;" that is, the cross being brighter than the sun, since this last will be darkened, and hide himself, and that will appear when it would not appear, unless it were far brighter than the beams of the sun. But wherefore doth the sign appear? In order that the shamelessness of the Jews may be more abundantly silenced. For having the cross as the greatest plea, Christ thus cometh to that judgment-seat, showing not His wounds only, but also the death of reproach. "Then shall the tribes mourn," for there shall be no need of an accusation, when they see the cross; and they shall mourn, that by His death they are nothing benefited; because they crucified Him whom they ought to have adored. Seest thou how fearfully He has pictured His coming? how He has stirred up the spirits of His disciples? For this reason, let me add, He puts the mournful things first, and then the good things, that in this way also He may comfort and refresh them. And of His passion He suggests to them the remembrance, and of His resurrection, and with a display of glory, He mentions His cross, so that they may not be ashamed nor grieve, whereas indeed He cometh then setting it forth for His sign. And another saith, "They shall look on Him whom they pierced." Therefore it is that they shall mourn, when they see that this is He. And forasmuch as He had made mention of the cross, He added, "They shall see the Son of Man coming," no longer on the cross, but "in the clouds of Heaven, with power and great glory." For think not, He meaneth, because thou hearest of the cross, that it is again anything mournful, for He shall come with power and great glory. But He bringeth it, that their sin may be self-condemned, as if any one who had been struck by a stone, were to show the stone itself, or his garments stained with blood. And He cometh in a cloud as He was taken up, and the tribes seeing these things mourn. Not however that the terrors shall with them proceed no further than mournings; but the mourning shall be, that they may bring forth their sentence from within, and condemn themselves.

We are invited to flock to Christ's passion wheresoever in Scripture it is read of, that through it we may be able to come to God's word. These things, therefore, shall not come to pass by any diminution of light, for in another place we read that the light of the sun shall be sevenfold; but by comparison with real light, all things shall seem dim. By the powers of heaven, we understand the bands of the Angels. Rightly does He say, the tribes of the earth, for they shall mourn who have no citizenship in heaven, but are written in earth. (Jer. 17:13.)

(Ep. 199, 39.) Or, the Church is the sun, moon, and stars, to which it is said, Fair as the moon, bright as the sun. Then shall the sun be darkened, and the moon shall not give her light (Song of Solomon 6:10.), because in that ungoverned fury of wicked persecutors, the Church shall not be seen. Then shall the stars fall from heaven, and the powers of heaven shall be shaken, because many, who seemed to be shining in God's grace, shall give way to their persecutors, and shall fall, and even the stoutest believers shall be shaken. And these things shall be after the tribulation of those days, not because they shall happen when the whole persecution is overpast, but because the tribulation shall be first, that the falling away may come after. And because it shall be so throughout all those days, it shall be after the tribulation of those days, yet on those very days.
