Lutheranism
(a) The prophetical office (munus, or officium propheticum) includes teaching and the miracles of Christ.
(b) The priestly office (munus sacerdotale) consists of the satisfaction made for the sins of the world by the death on the cross, and in the continued intercession of the exalted Savior for his people (redemptio et intercessio sacerdotalis).
(c) The kingly office (munus regium), whereby Christ founded his kingdom, defends his church against all enemies, and rules all things in heaven and on earth. The old divines distinguish between the reign of nature (regnum naturae sive potentiae), which embraces all things; the reign of grace (regnum gratiae), which relates to the church militant on earth; and the reign of glory (regnum gloriae), which belongs to the church triumphant in heaven.
The theologians who followed Luther and Melanchthon down to the middle of the seventeenth century treat Christ's saving work under the two heads of king and priest. Calvin, in the first edition of his Institutes of the Christian Religion (1536), did the same, and it was not till the third edition (1559) and the Genevan Catechism that he fully presented the three offices. This convenient threefold division of the office of Christ was used by the theologians of both confessions during the seventeenth century. Ernesti opposed it, but Schleiermacher restored it.
