Those who misapply the principle of baptism do not understand what baptism does. Since they miss the essential connection to the voluntary aspect of the atonement, they effectively deny that part of the atonement. It is that tacit denial of an important aspect of the atonement that becomes equivalent to denying the mercies of the Atoning Messiah. By making baptism similar to the resurrection, they are denying an essential aspect of the atonement.
