There's a difference between Hades and Gehenna. I always thought they were the same. It's the difference between hell and purgatory. Hades is a place you can't come back from
Gehenna is the name of the valley of the "sons of Hinnom," which is a place people sacrificed to Baal. The sacrifice was often people but more often garbage was thrown there. It was a dreadful place. The gases piled up in this dump and sometime combusted into tiny fires. Maybe the Gospels mentioning everlasting fire were thinking of the smoldering refuse in Gehenna.
Am I wrong in thinking that when Jesus descended to the dead, in the Apostle's Creed, He went down to get those people in Gehenna?
