Bede the Venerable

Our Lord continues the words which He had begun against the hypocrites, saying, For a good tree bringeth not forth corrupt fruit; i. e. as if He says, If thou wouldest have a true and unfeigned righteousness, what thou settest forth in words make up also in works, for the hypocrite though he pretends to be good is not good, who doeth evil works; and the innocent though he be blamed, is not therefore evil, who doeth good works.
