Catena Aurea · Lukasevangelium 17
Lk 17, Verses 31–33English original
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.
Because thus she looked behind, she lost the gift of her nature. For Satan is behind, behind also Sodom. Wherefore flee from intemperance, turn away from lust, for recollect, that he who turned not back to his old pursuits escaped, because he reached the mount; whereas she looking back to what was left behind, could not even by the aid of her husband reach the mount, but remained fixed.
