The Greek noun euporia (εὐπορία) means wealth, prosperity, financial ease, abundance of means. The noun form of euporeō, it appears once in the NT — Acts 19:25 — in a context dripping with irony: the silversmith Demetrius rallies his guild around their euporia (their livelihood) which is threatened by Paul's gospel.
Acts 19:25 is one of the NT's most honest exposures of economic idolatry. Demetrius frames his grievance in religious terms ("the great goddess Artemis may be counted as nothing") but reveals his true motive first: "You know that from this business we have our wealth (euporia)." The gospel always threatens certain economies — those built on false worship, exploitation, and the manufacture of idols. When people encounter Christ, shrines close and silversmiths lose income. Demetrius is not wrong that Paul's preaching threatens his euporia; he is wrong that his euporia is worth protecting at the cost of truth. The church must be willing to threaten comfort and profit when truth demands it.
