(2:Macc.12:46): "It is a holy and wholesome thought to pray for the dead, that they may be loosed from sins."
Those in Heaven have no need for prayer; those in hell are beyond hope. Thus there must be a place for the dead where sins are expiated. Catholics maintained the Apocrypha, while the Reformers discarded it. The baby got thrown out with the bathwater, just so Purgatory could be eliminated.
