Bede the Venerable
Catena Aurea · Lukasevangelium 6
And he spake a parable unto them, Can the blind lead the blind? shall they not both fall into the ditch? The disciple is not above his master: but every one that is perfect shall be as his master. And why beholdest thou the mote that is in thy brother’s eye, but perceivest not the beam that is in thine own eye? Either how canst thou say to thy brother, Brother, let me pull out the mote that is in thine eye, when thou thyself beholdest not the beam that is in thine own eye? Thou hypocrite, cast out first the beam out of thine own eye, and then shalt thou see clearly to pull out the mote that is in thy brother’s eye.
Or the sense of this sentence depends upon the former, in which we are enjoined to give alms, and forgive injuries. If, says He, anger has blinded thee against the violent, and avarice against the grasping, how canst thou with thy corrupt heart cure his corruption? If even thy Master Christ, who as God might revenge His injuries, chose rather by patience to render His persecutors more merciful, it is surely binding on His disciples, who are but men, to follow the same rule of perfection.
