Bede the Venerable
Catena Aurea · Lukasevangelium 17
And as it was in the days of Noe, so shall it be also in the days of the Son of man. They did eat, they drank, they married wives, they were given in marriage, until the day that Noe entered into the ark, and the flood came, and destroyed them all. Likewise also as it was in the days of Lot; they did eat, they drank, they bought, they sold, they planted, they builded; But the same day that Lot went out of Sodom it rained fire and brimstone from heaven, and destroyed them all. Even thus shall it be in the day when the Son of man is revealed.
The coming of our Lord, which He had compared to lightning flying swiftly across the heavens, He now likens to the days of Noah and Lot, when a sudden destruction came upon mankind.
