re: “Interestingly, the early Christians didn’t really believe in Hell. Instead, they believe in the Jewish Sheol, a zombie-like place where the dead went for eternity. They believed that Satan and his minions would be cast into the lake of fire eventually, but not man.”
It is true that the Old Testament is a bit vague about what Hell exactly is. It is also true that the word “hell” is the English word for “sheol”. However, Jesus was very clear about Hell. He taught that it was a real place of conscious eternal punishment - a place to be avoided at all costs. So, I believe you are greatly mistaken about the early Christians’ beliefs regarding Hell since they believed Jesus’s words implicitly. The Apostles were also clear about Hell being a place of torment.
The only place in the New Testament where the lake of fire is mentioned is in the book of Revelation which also declares that all those who reject Christ and whose names were not written in the “Book of Life” were also cast into the Lake of fire - along with Satan and the fallen angels. So, once again, I think you are mistaken about what early Christians believed. Since Revelation was written by the Apostle John, who was widely known among the early believers, I doubt that his writings were unknown to them either.
“The Apostles were also clear about Hell being a place of torment.”
True, although as you point out, the lake of fire is only mentioned in Revelations as being the place where Satan and his minions go after the Last Judgement.
So although Hell is described as a place of torment, it’s hard to say what that means exactly. Some theologians think that the condemned simply wander forever in a state of darkness and misery, knowing that they cannot be with God.
Which is a bit like the Greek Hades (described as a dark, shadowy place where the dead wander).
You can read a more detailed description of hell in the Apocolypse of Peter. Go the the link below and go to the reference section. If there was a one and a trillion chance of me going to place like that..I’ll pass. BTW, it was removed by the early church.
