We believe that immersion is the only method of baptism taught and commanded in the Scriptures. While it is an important ritual, it has no saving or delivering or sanctifying power. As a ritual it portrays the believer's new position in Christ and his belief in his own future bodily resurrection. Spiritual rebirth is necessary before water baptism is to be performed.
When a believer is taken into the water he is publicly identifying with the death and burial of Christ. When he comes up out of the water he is identifying with the resurrection of Christ and his own future bodily resurrection.
