Augustine of Hippo
Catena Aurea · Lukasevangelium 17
In that day, he which shall he upon the housetop, and his stuff in the house, let him not come down to take it away: and he that is in the field, let him likewise not return back. Remember Lot’s wife. Whosoever shall seek to save his life shall lose it; and whosoever shall lose his life shall preserve it.
For he is on the housetop who, departing from carnal things, breathes as it were the free air of a spiritual life. But the vessels in the house are the carnal senses, which many using to discover truth which is only taken in by the intellect, have entirely missed it. Let the spiritual man then beware, lest in the day of tribulation he again take pleasure in the carnal life which is fed by the bodily senses, and descend to take away this world’s vessels. It follows, And he that is in the field, let him not return back; that is, He wholabours in the Church, as Paul planting and Apollos watering, let him not look back upon the worldly prospects which he has renounced.
