The frequent New Testament affirmations that Jesus was "raised from the dead" presuppose that the crucified one sojourned in the realm of the dead prior to his resurrection. Acts 3:15; Rom 8:11; I Cor 15:20; cf. Heb 13:20. This was the first meaning given in the apostolic preaching to Christ's descent into hell: that Jesus, like all men, experienced death and in his soul joined the others in the realm of the dead. But he descended there as Saviour, proclaiming the Good News to the spirits imprisoned there. Cf. I Pt 3:18-19.
