Bede the Venerable — as excerpted in the Catena Aurea on Luke 20:9-18

“(in Marc. 12.) Or understanding it morally; to every one of the faithful is let out a vineyard to cultivate, in that the mystery of baptism is entrusted to him to work out. One servant is sent, a second and a third, when the Law, the Psalms, and the Prophets are read. But the servant who is sent is said to be treated despitefully or beaten, when the word heard is despised or blasphemed. The heir who is sent that man kills as far as he can, who by sin tramples under foot the Son of God. (Heb. 6:6.) The wicked husbandman being destroyed, the vineyard is given to another, when with the gift of grace, which the proud man spurned, the humble are enriched.”
