31. By the public ministry we mean the office by which the Word of God is preached and the Sacraments are administered by order and in the name of a Christian congregation. Concerning this office we teach that it is a divine ordinance; that is, the Christians of a certain locality must apply the means of grace not only privately and within the circle of their families nor merely in their common intercourse with fellow-Christians, John 5:39; Eph. 6:4; Col. 3:16, but they are also required, by the divine order, to make provision that the Word of God be publicly preached in their midst, and the Sacraments administered according to the institution of Christ, by persons qualified for such work, whose qualifications and official functions are exactly defined in Scripture, Titus 1:5; Acts 14:23; 20:28; 2 Tim. 2:2.
32. Although the office of the ministry is a divine ordinance, it possesses no other power than the power of the Word of God, 1 Pet. 4:11; that is to say, it is the duty of Christians to yield unconditional obedience to the office of the ministry whenever, and as long as, the minister proclaims to them the Word of God, Heb. 13:17, Luke 10:16. If, however, 6:30-8:30 the minister, in his teachings and injunctions, were to go beyond the Word of God, it would be the duty of Christians not to obey, but to disobey him, so as to remain faithful to Christ, Matt. 23:8. Accordingly, we reject the false doctrine ascribing to the office of the ministry the right to demand obedience and submission in matters which Christ has not commanded.
33. Regarding ordination we teach that it is not a divine, but a commendable ecclesiastical ordinance. (Smalcald Articles. Triglot, p. 525, paragraph 70; M., p. 342.)
