When the Lord died in the flesh, His soul was separated from His flesh, but His divinity was not separated from His flesh nor from His soul. The soul departed to Hades to preach those who had died in the hope of the resurrection, for Satan has no power over them. St. Ambrose said: “It is obvious that the Lord Jesus did not fall under the power of darkness but rather He abolished its dominion, preaching even to the dead in Hades to liberate them (1).” But who are the ones to whom He preached? There are many explanations:
A. The opinion of St. Athanasius, St. Cyril, and St. Jerome: After the Lord’s death in the flesh, He descended into Hades and preached to those who did not believe Noah when he was warning them about the flood, but when some saw the rain pouring, they repented and asked for mercy.
B. The opinion of St. Augustine: The Lord Jesus, with His Holy Spirit, preached the people, through Noah, and warned them of the flood, so they may repent, but they did not believe. By saying “in the prison”, he means the spirits who were in the flesh. Only eight, Noah, his wife, his three sons and their wives were saved through this preaching.
C. The opinion of Tertullian (2): The number eight was to show that the creation started with Adam and Eve, a man with only one wife, and also, the new world, after the flood, Noah and his sons, each having one wife.
D. The opinion of Fr. Hippolytus (3): “He arranged everything on earth; therefore, He became man to restore to us our image through Himself, also He arranged everything under the earth for He was numbered with the dead preaching the Gospel to the souls of the saints who died on the hope of the resurrection. Through death, He conquered death.”
E. The opinion of St. Irenaeus (4): After mentioning the people who sinned in the Old Testament, he said that the Lord descended to the deep earth proclaiming His ascension, declaring the forgiveness of sins to those who believe in Him. All those who believed in Him, hoped in Him and declared His coming and submitted to His blessings, that is, all the prophets, the fathers, He forgave them their sins, in as much as He forgave us.
F. The opinion of St. Clement of Alexandria (5): He relied on what Job said in ch.28:24, that He looks to the ends of the earth and sees under the whole heavens. He descended and preached not only to those who hoped in His salvation, but to the Gentiles, who in their ignorance, lived righteously according to their law.
