Addressing those who would offer that the act of water baptism causes the remission of sin . . . using Acts 2:38 as proof.
There is much missing from Acts 2:38 that prevents its use as a proof text for the act of water baptism conferring righteousness upon the subject of the baptism. To use this text for such a proof, we must obtain all that we need in the way of proof from the single word translated as "for" in the KJV.
Acts 2:38
38 Then Peter said unto them, Repent, and be baptized every one of you in the name of Jesus Christ for the remission of sins, and ye shall receive the gift of the Holy Ghost.(KJV)
You would equate "for" to mean "to bring about" or something similar. The word simply does not have that meaning in this context. Particularly in light of clarifying text located later in Acts, and also in Romans (more on this later).
Omitting the parenthetical clause from the midst of 2:38, to help us see the key grammatical elements involved in this translation, we get the essence of the command " . . . be baptized . . . for the remission of sins." This instruction can perhaps be more easily understood if we substitute less "spiritual" (but more familiar) terms. Consider a military band, assembled for inspection and review. One of the soldiers is to be recognized for heroism. His commander might order him forward by saying, "Step forward and be decorated for bravery."
Which is the symbol, and which is the issue of substance? What is the cause that led to an appropriate response? His bravery precipitated his being decorated. If he had not been brave there would be nothing to be decorated "for."
Back to the Bible text. If those Peter was addressing had no remission of sin through Christ, if they had not received His righteousness imputed to them because of their faith in Him, there would have been no remission to be baptized "for."
And from whence comes the imputing of that righteousness? From God, when the heart of the sinner turns to Christ as his only hope for salvation. Consider the following.
Acts 10:43
43 To him give all the prophets witness, that through his name whosoever believeth in him shall receive remission of sins. (KJV)
Rom 10:9-11
9 That if thou shalt confess with thy mouth the Lord Jesus, and shalt believe in thine heart that God hath raised him from the dead, thou shalt be saved.
10 For with the heart man believeth unto righteousness; and with the mouth confession is made unto salvation
(recall that salvation can include justification or sanctification or both - see my post in "What is salvation").
11 For the scripture saith, Whosoever believeth on him shall not be ashamed. (KJV)
I am afraid that to attribute the remission of sins to the washing with water is to confuse the celebration, the symbolic expression of the spiritual cleansing that comes through faith in Christ, with the belief unto justification.
Like the Wizard in the Emerald City of Oz, you are crediting the medal with instilling valor. It is cute in a fantasy story. But it is very dangerous in theology.
