Where did people who died before Christ go?
According to the Catechism of the Catholic Church, before the Resurrection, Abraham, Noah, Moses, Adam and Eve, and all the righteous were in the Limbo of the Fathers (limbus patrum) where they remained until “in his human soul united to his divine person, the dead Christ went down to the realm of the dead. He opened heaven’s gates for the just who had gone before him” (CCC 637).
Today a great silence reigns on earth, a great silence and a great stillness. A great silence because the King is asleep. The earth trembled and is still because God has fallen asleep in the flesh and he has raised up all who have slept ever since the world began. . . . He has gone to search for Adam, our first father, as for a lost sheep. Greatly desiring to visit those who live in darkness and in the shadow of death, he has gone to free from sorrow Adam in his bonds and Eve, captive with him—he who is both their God and the son of Eve. . . ."I am your God, who for your sake have become your son. . . I order you, O sleeper, to awake. I did not create you to be a prisoner in hell. Rise from the dead, for I am the life of the dead." (CCC 635)
