Ambrose of Milan
Catena Aurea · Lukasevangelium 21
But when ye shall hear of wars and commotions, be not terrified: for these things must first come to pass; but the end is not by and by. Then said he unto them, Nation shall rise against nation, and kingdom against kingdom: And great earthquakes shall be in divers places, and famines, and pestilences; and fearful sights and great signs shall there be from heaven.
There are also other wars which the Christian wages, the struggles of different lusts, and the conflicts of the will; and domestic foes are far more dangerous than foreign.
