Bede the Venerable
Catena Aurea · Markusevangelium 13
And then if any man shall say to you, Lo, here is Christ; or, lo, he is there; believe him not: For false Christs and false prophets shall rise, and shall shew signs and wonders, to seduce, if it were possible, even the elect. But take ye heed: behold, I have foretold you all things. But in those days, after that tribulation, the sun shall be darkened, and the moon shall not give her light, And the stars of heaven shall fall, and the powers that are in heaven shall be shaken. And then shall they see the Son of man coming in the clouds with great power and glory. And then shall he send his angels, and shall gather together his elect from the four winds, from the uttermost part of the earth to the uttermost part of heaven.
(ubi sup.) For the stars in the day of judgment shall appear obscure, not by any lessening of their own light, but because of the brightness of the true light, that is, of the most high Judge coming upon them; although there is nothing to prevent its being taken to mean, that the sun and moon with all the other heavenly bodies then for a time are really to lose their light, just as we are told was the case with the sun at the time of our Lord’s Passion. But after the day of judgment, when there shall be a new sky and a new earth, then shall happen what Isaiah says: Moreover, the light of the moon shall be as the light of the sun, and the light of the sun shall be sevenfold. (Isa. 30:26) There follows, And the powers of heaven shall be shaken.
