The Greek adjective enochos means liable, guilty, or subject to a penalty — held within (the grasp of) a legal charge or obligation. It combines en (in) and echo (to hold), creating the image of being 'held in' legal accountability.
Jesus uses enochos in the Sermon on the Mount to escalate legal accountability: not just murder but anger makes one enochos to judgment (Matthew 5:21-22). In 1 Corinthians 11:27, eating the Lord's Supper unworthily makes one enochos — guilty against the body and blood of Christ. The word carries the weight of standing before a tribunal.
Theologically, enochos teaches that sin creates real legal liability before God. The only escape is the one who became enochos for us — Christ taking our guilt at the cross.
