Yes, not to mention "hearing", "having faith", "confessing", "repenting", etc.Nevertheless, I believe that it is a necessity for salvation (Acts 2:39, Romans 8:30).
The argument may be that that would make it a work of the law.
However, if that is the case, then confessing with your mouth the Lord Jesus, believing that God has raised Him from the dead, would also be a work of the law; since salvation cannot be accomplished without it.
Those who insert the false "anti-works doctrine" into the baptismal situation wish to deprive us of repentance from sin and remission of sins.
The perfect accommodation for continued sinning.
