Ambrose of Milan
Catena Aurea · Lukasevangelium 17
I tell you, in that night there shall be two men in one bed; the one shall be taken, and the other shall be left. Two women shall be grinding together; the one shall be taken, and the other left. Two men shall be in the field; the one shall be taken, and the other left. And they answered and said unto him, Where, Lord? And he said unto them, Wheresoever the body is, thither will the eagles be gathered together.
For God is not unjust that He should separate in His reward of their deserts men of like pursuits in life, and not differing in the quality of their actions. But the habit of living together does not equalize the merits of men, for not all accomplish what they attempt, but he only who shall persevere to the end shall be saved.
