Threefold office (munus triplex)

The scheme, systematised by Calvin, that organises Christ's mediatorial work under three anointed offices from Israel's story: prophet (revealing God), priest (offering the sacrifice and interceding), and king (ruling and defending).

Latin munus triplex, 'threefold office'; 'Christ / Messiah' means 'anointed one', and prophets, priests, and kings were anointed.

Deuteronomy 18:15–18 with Acts 3:22 (prophet); Psalm 110:4 with Hebrews 7 (priest); 2 Samuel 7:12–16 with Luke 1:32–33 (king); all three summarised in Hebrews 1:1–3.

Anticipated by Eusebius (Ecclesiastical History 1.3, naming all three) and used in scattered patristic and medieval theology; developed systematically by Calvin (Institutes II.15) and adopted into the Reformed catechisms (Heidelberg 31; Westminster), Lutheran theology, and (applied to all the baptised) the Catechism of the Catholic Church.

Its value is comprehensiveness: it covers the whole human predicament — ignorance (prophet), guilt (priest), bondage and disorder (king) — and the whole of the Old Testament's expectation, guarding against reducing Christ to any one role.

Whether the threefold division is the best frame (Barth reorders it; some prefer a two-office or narrative scheme); it is a heuristic, not a revealed formula.
