dikaiosune

What it means

In Greek usage outside the Bible, dikaiosune could mean a judge's fairness, a citizen's honesty in trade, or the general uprightness expected of someone living well in a community. It's a social word as much as a private one. A dikaios person was someone others could deal with safely — who paid debts, kept contracts, gave true testimony.

In the New Testament the word keeps that legal and relational shape but stretches to cover a person's whole standing before God. It can mean the right conduct God asks for, the right verdict a judge hands down, or the right status a person now has because God has declared it so. English has no single word that holds justice, fairness, uprightness, and right-standing together the way dikaiosune does.

What English does with it

English translations almost always reach for 'righteousness', occasionally 'justice' where the social sense is unmistakable, as in some renderings of Matthew's Beatitudes or Romans' discussion of God's dealings with sin. Choosing 'righteousness' pulls the word toward private piety; choosing 'justice' pulls it toward courts and society. Either choice quietly drops half of what the Greek was doing at once.

The common mistake

A well-worn but mistaken word study claims dikaiosune breaks down to mean 'right-wise-ness', a kind of moral scorecard for individuals. It doesn't work that way in Greek; the word was already in use for civic fairness and legal verdicts long before it picked up its theological sense. Treating it as purely personal morality misses the relational and social weight it always carried.
