The Novatians also are condemned, who would not absolve such as had fallen after Baptism, though they returned to repentance. They also are rejected who do not teach that remission of sins comes through faith but command us to merit grace through satisfactions of our own. Article XIII: Of the Use of the Sacraments. Of the Use of the Sacraments they teach that the Sacraments were ordained, not only to be marks of profession among men, but rather to be signs and testimonies of the will of God toward us, instituted to awaken and confirm faith in those who use them. Wherefore we must so use the Sacraments that faith be added to believe the promises which are offered and set forth through the Sacraments. They therefore condemn those who teach that the Sacraments justify by the outward act, and who do not teach that, in the use of the Sacraments, faith which believes that sins are forgiven, is required. Article XIV: Of Ecclesiastical Order. Of Ecclesiastical Order they teach that no one should publicly teach in the Church or administer the Sacraments unless he be regularly called. Article XV: Of Ecclesiastical Usages. Of Usages in the Church they teach that those ought to be observed which may be observed without sin, and which are profitable unto tranquillity and good order in the Church, as particular holy-days, festivals, and the like. Nevertheless, concerning such things men are admonished that consciences are not to be burdened, as though such observance was necessary to salvation. They are admonished also that human traditions instituted to propitiate God, to merit grace, and to make satisfaction for sins, are opposed to the Gospel and the doctrine of faith. Wherefore vows and traditions concerning meats and days, etc., instituted to merit grace and to make satisfaction for sins, are useless and contrary to the Gospel. Article XVI: Of Civil Affairs. Of Civil Affairs they teach that lawful civil ordinances are good works of God, and that it is right for Christians to bear civil office, to sit as judges, to judge matters by the Imperial and other existing laws, to award just punishments, to engage in just wars, to serve as soldiers, to make legal contracts, to hold property, to make oath when required by the magistrates, to marry a wife, to be given in marriage. They condemn the Anabaptists who forbid these civil offices to Christians. They condemn also those who do not place evangelical perfection in the fear of God and in faith, but in forsaking civil offices, for the Gospel teaches an eternal righteousness of the heart. Meanwhile, it does not destroy the State or the family, but very much requires that they be preserved as ordinances of God, and that charity be practiced in such ordinances. Therefore, Christians are necessarily bound to obey their own magistrates and laws save only when commanded to sin; for then they ought to obey God rather than men. Acts 5, 29. Article XVII: Of Christ's Return to Judgment.
