Catechesis: Holy Baptism

Faith must have something that it believes, that is, of which it takes hold and upon which it stands and rests. So faith clings to the water and believes that in Baptism, there is pure salvation and life. This is not through the water (as we have stated well enough), but through the fact that it is embodied in God's Word and institution, and that God's name abides in it.—LC IV:29

Therefore, it makes sense that whoever rejects Baptism rejects God's Word, faith, and Christ, who directs us to Baptism and binds us to Baptism.—LC IV:31
