Burial
Although in Bible times bodies were normally placed in tombs, caves or buried there is no mention in Scripture forbidding cremation. At the resurrection of the dead God is able to restore all those who have returned to dust, either by cremation or due to natural decay.
At baptism a person is submersed in water, symbolizing the burial of the ‘old life’ and raised up out of the water to a resurrected ‘new life’ in Christ (Rom 6:4).
