Smalcald Articles - Part 3, Article 5

Part III, Article V. Of Baptism.

1] Baptism is nothing else than the Word of God in the water, commanded by His institution, or, as Paul says, a washing in the Word; as also Augustine says: Let the Word come to the element, and it becomes a Sacrament. 2] And for this reason we do not hold with Thomas and the monastic preachers [or Dominicans] who forget the Word (God's institution) and say that God has imparted to the water a spiritual power, which through the water washes away sin. 3] Nor [do we agree] with Scotus and the Barefooted monks [Minorites or Franciscan monks], who teach that, by the assistance of the divine will, Baptism washes away sins, and that this ablution occurs only through the will of God, and by no means through the Word or water.
4] Of the baptism of children we hold that children ought to be baptized. For they belong to the promised redemption made through Christ, and the Church should administer it [Baptism and the announcement of that promise] to them.
