In Christian theology, the Harrowing of Hell (Latin: Descensus Christi ad Inferos; Greek: Ἡ εἰς ᾍδου κάθοδος τοῦ Χριστοῦ – "the descent of Christ into Hell" or "Hades") is the period of time between the Crucifixion of Jesus and his resurrection. In triumphant descent, Christ brought salvation to the souls held captive there since the beginning of the world.
Christ's descent into the world of the dead is referred to in the Apostles' Creed and the Athanasian Creed (Quicumque vult), which state that he "descended into the underworld" (descendit ad inferos), although neither mention that he liberated the dead. His descent to the underworld is alluded to in the New Testament in 1 Peter 4:6, which states that the "good tidings were proclaimed to the dead". The Catechism of the Catholic Church notes Ephesians 4:9, which states that "[Christ] descended into the lower parts of the earth", as also supporting this interpretation. These passages in the New Testament have given rise to differing interpretations. The Harrowing of Hell is commemorated in the liturgical calendar on Holy Saturday.
