Baptism of the Dead

Charles Buck Theological Dictionary

A custom which anciently prevailed among some people in Africa, of giving baptism to the dead. The third council of Carthage speaks of it as a thing that ignorant Christians were fond of : Gregory Nazianzin also takes notice of the same superstitious opinion. The practice seems to be grounded on a vain idea, that, when men had neglected to receive baptism in their life-time, some compensation might be made for this default by receiving it after death.
