Purgatory

Purgatory in Roman Catholic theology is an intermediate state after physical death in which those destined for heaven "undergo purification, so as to achieve the holiness necessary to enter the joy of heaven". Only those who die in the state of grace but have not in life reached a sufficient level of holiness can be in Purgatory, and therefore no one in Purgatory will remain forever in that state or go to hell.
