In Catholic theology, Limbo is the afterlife condition of those who die in original sin without being assigned to the Hell of the Damned. Medieval theologians of Western Europe described the underworld as divided into three distinct parts: Hell of the Damned, Limbo of the Fathers or Patriarchs, and Limbo of the Infants. The Limbo of the Fathers is an official doctrine of the Catholic Church, but the Limbo of the Infants is not. The concept of Limbo comes from the idea that, in the case of Limbo of the Fathers, good people were not able to achieve heaven just because they were born before the birth of Jesus Christ. This is also true for Limbo of the Infants in that simply because a child died before baptism, does not mean they deserve punishment, though they cannot achieve salvation.

The afterlife or life after death is a purported existence in which the essential part of an individual's stream of consciousness or identity continues to exist after the death of their physical body. The surviving essential aspect varies between belief systems; it may be some partial element, or the entire soul or spirit, which carries with it one's personal identity.
