Bede the Venerable — as excerpted in the Catena Aurea on Luke 11:33-36

“Now when He adds, If thy whole body therefore, &c. by the whole of our body He means all our works. If then thou hast done a good work with a good intention, having in thy conscience nothing approaching to a dark thought, though it chance that thy neighbour is injured by thy good actions, nevertheless for thy singleness of heart shalt thou be rewarded with grace here, and with glorious light hereafter; which he signifies, adding, And as the bright shining of a candle shall it give thee light. These words were especially directed against the hypocrisy of the Pharisees, who sought for signs that they might catch him.”
