Does Christianity teach that the soul is immortal?

Traditionally yes, but some theologians argue the New Testament emphasizes the resurrection of the body by God's power rather than the natural immortality of the soul, treating any continued existence as dependent on God.

Purgatory is the Catholic doctrine of a state of purification after death for those who die in God's grace but still need cleansing before entering heaven; it is rejected by Protestant churches and understood differently in Orthodoxy.

Death and the Intermediate State

This topic concerns the Christian understanding of death and the condition of the dead between death and the final resurrection, the so-called intermediate state.

Definition

The doctrine of human death and the state of the dead prior to the general resurrection.

Scope

This topic examines theological accounts of death, the question of whether human beings possess a naturally immortal soul or depend on resurrection, the various proposals for the intermediate state (conscious existence with Christ, soul sleep, or immediate resurrection in God's eternity), and the disputed doctrine of purgatory. It relates these to the underlying anthropology (dualism, physicalism). The presentation is descriptive, comparing the positions rather than asserting one.

Core questions

Is the human soul naturally immortal, or is hope based on resurrection?
What is the condition of the dead before the resurrection?
Is there a purifying intermediate state (purgatory)?
How does anthropology shape views of the intermediate state?

Key theories

Resurrection rather than immortality: Oscar Cullmann's argument that the New Testament hope is the resurrection of the whole person by God's act, not the Greek idea of an inherently immortal soul surviving death, so that death is a real enemy overcome only in resurrection.
Conscious intermediate state: The traditional view that between death and resurrection the soul exists consciously, the saved 'with Christ', appealing to texts such as Jesus' words to the thief and Paul's desire to depart and be with Christ.

History

Patristic and medieval theology assumed a conscious intermediate state and developed the doctrine of purgatory, defined in the medieval West and rejected by the Reformers. The twentieth century saw renewed debate, with Cullmann contrasting biblical resurrection with Greek immortality, and others (such as Rahner) proposing resurrection in death, while contemporary physicalist anthropologies have reopened the question of personal continuity.

Debates

Immortality of the soul versus resurrection: Whether Christian hope rests on a naturally immortal soul that survives death or on God's resurrection of the whole person, with implications for how the dead exist before the end.
Purgatory: Whether there is a state of postmortem purification for the saved, affirmed by Catholicism and (differently) Orthodoxy but denied by Protestants as lacking scriptural warrant and undermining grace.
