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.
