held fast in the wrong so that punishment can follow: answerable to a court, deserving of a sentence, or guilty in relation to what has been violated
This is a courtroom word. It does not describe a feeling, and on its own it does not even describe a completed verdict. It describes a position: a person is now held in the wrong, and something is coming. The picture underneath it is one of being gripped, since it is built on a verb that means to hold someone in something (ἐνέχω). Whoever this word describes is caught and cannot get free of what is owed.
What the word points at depends on what comes next in the sentence, and the New Testament uses all three patterns:
- a court a person must answer to, as in the warnings of Matthew 5:21 and Matthew 5:22
- a punishment a person now deserves, most starkly the death sentence pronounced at the trial of Jesus
- an offense committed or a person wronged, so that someone can be guilty in relation to the body and blood of the Lord
Because of that flexibility, one English word rarely serves twice in a row. Translators write "liable to judgment" in one line, "deserving death" in another, "guilty of" in a third, and "accountable for" in a fourth. Each of those choices carries only part of what the Greek does. The steady element under all of them is exposure: a person standing exactly where the penalty can reach.
James pushes the word furthest. Someone who keeps the whole law but trips at a single point has become this word with respect to all of it. The law, on that reading, cannot be broken in pieces.
