WHAT IT MEANS TO BE BAPTIZED
Now to be baptized in the name of Christ is to be enrolled, entered, and received into the covenant and family, and so into the inheritance of the sons and daughters of God; yes, and in this life to be called after the name of God; that is to say, to be called a child of God; to be cleansed also from the filthiness of sins, and to be granted the manifold grace of God, in order to lead a new and innocent life. Baptism, therefore, calls to mind and renews the great favor God has shown to the race of mortal humans. For we are all born in the pollution of sin and are the children of wrath. But God, who is rich in mercy, freely cleanses us from our sins by the blood of His Son, and in Him rebirths us to be His sons and daughters, and by a holy covenant joins us to himself, and enriches us with various gifts, that we might live a new life. All these things are assured by baptism. For inwardly we are regenerated, purified, and renewed by God through the Holy Spirit; and outwardly we receive the assurance of the greatest gifts in the water, by which also those great benefits are represented, and, as it were, set before our eyes to be beheld.
WE ARE BAPTIZED WITH WATER
And therefore we are baptized, that is, washed or sprinkled with visible water. For the water washes dirt away, and cools and refreshes hot and tired bodies. And the grace of God performs these things for souls, and does so invisibly or spiritually.
THE OBLIGATION OF BAPTISM
Moreover, God also separates us from all strange religions and peoples by the symbol of baptism, and consecrates us to himself as His property. We, therefore, confess our faith when we are baptized, and obligate ourselves to God for obedience, mortification of the flesh, and newness of life. Hence, we are enlisted in the holy military service of Christ that all our life long we should fight against the world, Satan, and our own flesh. Moreover, we are baptized into one body of the Church, that with all members of the Church we might beautifully concur in the one religion and in mutual services.Selah.
