Augustine of Hippo
Catena Aurea · Lukasevangelium 21
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; 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. And then shall they see the Son of man coming in a cloud with power and great glory.
(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.
