In Christian teaching about the afterlife, what does the term “limbo of the patriarchs” traditionally describe?

In Christian teaching about the afterlife, the limbo of the patriarchs traditionally describes the abode of the righteous dead before Christ.

The concept, also called the bosom of Abraham, developed from biblical passages and later theological reflection. It describes righteous people who died before Jesus’ death and resurrection as awaiting redemption rather than suffering the punishment assigned to the wicked.

Medieval Christian theologians connected this idea with Christ’s descent to the dead and his liberation or admission of the righteous. The doctrine helped explain how figures such as Abraham, Moses, and the prophets could be righteous while still living before the Christian understanding of salvation was completed.

This idea differs from the separate theological proposal sometimes called limbo of the infants. The two concepts have different subjects and histories. Neither should be confused with purgatory, which Catholic theology describes as purification for those already destined for heaven.
