I am seeking understanding of your position, not debating, but I truly see the possibility of your position that baptism is a rite through divine grace is conferred. Is that correct in describing your position?What is achieved thru Holy Baptism is the forgiveness of sins. THAT is the work of God, not of man. Pouring water and saying the Baptismal words are not work. The forgiveness of sins IS, but THAT is the work of God. And it is God's work that saves us.
If that correctly describe the LCMS position, then it is logical to ask whether water in the rite of baptism is a necessary component whereby forgiveness of sins is granted. More to the point, according to Missouri Synod theology can there be a "dry cleaning" without any water whereby sins are forgiven?
If you choose to not answer that due to my unintentional breaking the rules of CARM, your silence will be sufficient
