Bryan Spinks first outlines Luther's high view of Baptism as the outward sign of Justification, as something God does. He then considers both of Luther's revisions of the Baptismal Liturgy in order to make the glory of God's action manifest. Luther lists non-essential ceremonies, then the 'integral' parts of the Liturgy – vows, immersion and the triune name. He lists those things which can take away from the 'glory of Baptism'. Spinks adds a note on Luther's view of Confirmation and concludes that Luther's chief concern was that Baptism should be the sacrament of salvation.
