Gregory the Great — as excerpted in the Catena Aurea on Matthew 22:1-14

“(ubi sup.) Or, The armies of our King are the legions of His Angels. He is said therefore to have sent His armies, and to have destroyed those murderers, because all judgment is executed upon men by the Angels. He destroys those murderers, when He cuts off persecutors; and burns up their city, because not only their souls, but the body of flesh they had tenanted, is tormented in the everlasting fire of hell.”
