And if your right eye causes you to offend, pluck it out, and cast it from you: for it is better for you that one of your members should perish, and not that your whole body should be cast into hell.
All Commentaries on Matthew 5:29 Go To Matthew 5
Hilary of Poitiers
AD 368
As the degree of innocence increases, faith becomes more advanced. For we are advised to be free not only from our own particular faults but also from those things that affect us outwardly. For is it not because of sin that the bodily members were condemned in the first place? The right eye is no less sinister than the left. It is pointless to chastise a foot that is unaware of lust and thus involves no grounds for punishment. But our members indeed do differ from each other while we are all one body. We are here being advised to pluck out inordinate loves or friendships if they are the occasion that leads us further into wrongdoing. We would do well to not even have the benefit of a member, like an eye or a foot, if it furnishes the avenue by which one is drawn by excessive affections into a partnership with hell. Even the cutting away of a member might be beneficial if the heart (figuratively speaking) were also able to be cut away. But if the impulse of the heart is left unchanged, the cutting away of a member would be pointless.
