And then shall appear the sign of the Son of man in heaven: and then shall all the tribes of the earth mourn, and they shall see the Son of man coming in the clouds of heaven with power and great glory.
All Commentaries on Matthew 24:30 Go To Matthew 24
Augustine of Hippo
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,” because in that ungoverned fury of wicked persecutors, the Church shall not be seen.
