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.
Now Noah builds the ark mystically. The Lord builds His Church of Christ’s faithful servants, by uniting them together in one, as smooth pieces of wood; and when it is perfectly finished, He enters it: as at the day of Judgment, He who ever dwells within His Church enlightens it with His visible presence. But while the ark is in building, the wicked flourish, when it is entered, they perish; as they who revile the saints in their warfare here, shall when they are crowned hereafter be smitten with eternal condemnation.
