And if your eye offend you, pluck it out, and cast it from you: it is better for you to enter into life with one eye, rather than having two eyes to be cast into hell fire.
All Commentaries on Matthew 18:9 Go To Matthew 18
Hilary of Poitiers
AD 368
Or; The lowliness of His passion is the scandal of the world, which refused to receive the Lord of eternal glory under the disgrace of the Cross. And what more dangerous for the world than to have rejected Christ? And He says that offences must needs come, forasmuch as in the sacrament of restoring to us eternal life, all lowliness of suffering was to be fulfilled in Him.
Or; By the man is denoted the Jewish people, as the introducers of all this offence that is about Christ’s passion; for they brought upon the world all the danger of denying Christ in His passion, of whom the Law and the Prophets had preached that He should suffer.
