I’m pretty sure the gospel translations we have today are include some significant edits, with all the others derived from Mark. What I don’t know is if mentions of Hell or Hellfire as an afterlife torture program are from the first century as I am not a biblical scholar. The common feared fate was gehenna, the garbage dumpsite where refuse was burned, including the bodies of the poor, outcasts and criminals.

I wrote a blog cataloguing Hell in 2016. I’ve been told Limbo was never a part of it though George Carlin was taught about Limbo when he was in parochial school, so there’s a lot of misinformation and changing opinions within ecclesiastic scholarship.

But I also don’t know if there was a definite period in which spiritual interpretations were added in. The scholarly consensus is that the apostles expected the world to end within their lifetime, and Jesus would return to collect them all and sort everyone out. They would not need to die to see their eternal life, which was literal.

But that didn’t happen. In fact, Christian history teems with apocalyptic disappointments.
