Eusebius of Caesarea
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.
When also the Son of God shall come in glory, and shall crush the proud empire of the son of sin, the angels of heaven attending Him, the doors of heaven which have been shut from the foundation of the world shall be opened, that the things that are on high may be witnessed.
