Bede the Venerable
Catena Aurea · Lukasevangelium 17
Then said he unto the disciples, It is impossible but that offences will come: but woe unto him, through whom they come! It were better for him that a millstone were hanged about his neck, and he cast into the sea, than that he should offend one of these little ones.
This is spoken according to the custom of the province of Palestine; for among the ancient Jews the punishment of those who were guilty of the greater crimes was that they should be sunk into the deep with a stone tied to them; and in truth it were better for a guilty man to finish his bodily life by a punishment however barbarous, yet temporal, than for his innocent brother to deserve the eternal death of his soul. Now he who can be offended is rightly called a little one; for he who is great, whatsoever he is witness of, and how great soever his sufferings, swerves not from the faith. As far then as we can without sin, we ought to avoid giving offence to our neighbours. But if an offence is taken at the truth, it is better to let the offence be, than that truth should be abandoned.
