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.”
