But in those days, after that tribulation, the sun shall be darkened, and the moon shall not give her light,
All Commentaries on Mark 13:24 Go To Mark 13
Ambrose of Milan
AD 397
As in its monthly eclipse, the moon, by reason of the earth coming between it and the sun, disappears from view, so likewise the holy church, when the vices of the flesh stand in the way of the celestial light, can no longer borrow the splendor of its divine light from the sun of Christ…. Also the stars, that is, leaders surrounded by the praise of their fellow Christians, shall fall, as the bitterness of persecution mounts up.
