Catechesis: The Mass

We showed in our Confession our belief that the Lord’s Supper does not give grace by the outward act (ex opere operato) and that, when applied on behalf of others, alive or dead, it does not merit for them the forgiveness of sins, guilt, or punishment by the outward act. This position is supported by clear and firm proof. It is impossible to receive the forgiveness of our sins because of our own work by the outward act. The terrors of sin and death must be overcome through faith when we comfort our hearts with the knowledge of Christ and believe that for His sake we are forgiven and that His merits and righteousness are granted to us, “since we have been justified by faith, we have peace.” (Romans 5:1) These things are so sure and firm that they can stand against all the gates of hell.—Ap XXIV:11, 12.
