Summary: The Catechism of the Catholic Church (promulgated 1992) gives the modern magisterial restatement of the descent. Under the article "He Descended into Hell" (§§632–635) it teaches that Christ's soul, truly joined to the dead, "descended there as Saviour, proclaiming the Good News to the spirits imprisoned there" (1 Pet 3:18–19) — that he delivered "the just who had gone before him," the holy souls who "awaited their Saviour in Abraham's bosom," but "did not descend into hell to deliver the damned." It consolidates Benedict XII and the patristic consensus into the Church's current authoritative formula, and carefully draws the line the descent does not cross: the freeing of the just, not a universal deliverance.
It is precisely these holy souls, who awaited their Saviour in Abraham's bosom, whom Christ the Lord delivered when he descended into hell.
— Catechism of the Catholic Church §633, vatican.va. The descent is real and salvific: §632 has it that Christ "descended there as Saviour, proclaiming the Good News to the spirits imprisoned there" (citing 1 Pet 3:18–19), and §633 identifies those he delivers as the OT righteous held in "Abraham's bosom" — the same emptied holding-place the Aquinas page calls the limbus patrum.
Jesus did not descend into hell to deliver the damned, nor to destroy the hell of damnation, but to free the just who had gone before him.
— Catechism of the Catholic Church §633, vatican.va. The Catechism draws the limit the patristic mainstream had left implicit: the descent frees the righteous dead, but is no universal second chance for the lost. This sides with Gregory the Great and Augustine against the more expansive reading floated by Clement of Alexandria (a postmortem repentance even for some in Hades), and bears directly on the content-of-the-proclamation argument.
The gospel was preached even to the dead.
— Catechism of the Catholic Church §634, vatican.va. Quoting 1 Pet 4:6, the Catechism makes the descent the completion of the gospel's reach across "all times and all places": redemption extends even to those who died before Christ. The risen Christ now holds "the keys of Death and Hades" (Rev 1:18; §635).
