“If your hand or your foot causes you to sin, cut it off”
Matthew 18:8–9
Figure of speechSettledJesus
If your hand or your foot causes you to sin, cut it off and throw it away. It is better for you to enter life crippled or lame than to have two hands and two feet and be thrown into the eternal fire. (Matthew 18:8–9 BSB)
What it sounds like today
Horrifyingly literal self-mutilation.
The cultural key
Deliberate hyperbole in the vein of rabbinic exaggeration: vivid overstatement to force a point. The tell: the teaching doesn't actually work literally (a blind man can still lust; the sin's source is the heart, as Jesus says elsewhere, Matthew 15:19). No early Christian community practiced it. The amputation hyperbole returns in the community discourse, now framed around the little ones: drastic action against whatever in you endangers the vulnerable ranks above bodily wholeness.
Recovered meaning
Treat sin surgically: whatever feeds it, however valued, however much a part of you it feels, must go, and go drastically. Amputation-level seriousness, not amputation.
