It would help if their assumptions weren’t so wrong. For example, the 2nd paragraph says:
"To be clear, we’re concerned here with the nature of Hell, not just its existence. In fact, you can’t escape the reality of Hell or final judgment in Scripture. It’s a topic taken up by every New Testament writer and it dominates the teaching of Jesus. Of the 12 times the Greek word for Hell (Gehenna) is used in the New Testament, 11 come from the lips of Christ. He said the most about Hell, so to deny the existence of Hell is to deny the teachings of Jesus."
However, “Gehenna” is NOT the Greek word for Hell. In fact, Gehenna is not actually a Greek word, but the Greek transliteration of Ga Hinnom, Hebrew for the valley of Hinnom just outside Jerusalem. The Greek word that best conveys the concept of Hell (ECT) is Tartarus. Tartarus in Greek Mythology was the torturous realm within Hades (the realm of the dead). If the NT writers intended to speak of ECT, Tartarus would have been the word to use, especially when writing to the Greeks. It’s also significant to note that Tartarus was not used in the LXX to translate Sheol; rather, the general term Hades (realm of the dead, grave) was used. It’s also significant to note that of the 11 times Gehenna is used by Jesus, it’s only 8 seperate passages, and of those 8, 2 are parallel passages of Matthew’s in Mark and Luke. So in reality there are only 6 distinct uses of Gehenna, all in Matthew, and of these 6 most are specifically leveled at the Pharisees. And the Pharisees surely understood the OT context of Gehenna as being a sign of Judgment against Israel’s wickedness, and there is evidence that they, the Pharisees, thought of it primarily as a place of fiery judgment and remedial punishment in the afterlife, an encounter with the fire of truth that purges one of evil. And of course, Matthew was written to the Jews who would have understood the intended meaning of Gehenna, and would not have mistaken it for the Greek myth Tartarus.
So Jesus did not warn of Hell, but warned the Jews of Gehenna, the judgment of God against Israel by Rome, and likely was warning specifically the Pharisees, even calling them “sons of Gehenna”.
And of course, James is the only other NT writer that speaks of Gehenna, and even there it is not a warning of a place someone will go, but a source from which someone speaks.
I weary of people, especially theologians who should know better, making such outlandish ignorant statements like in the 2nd paragraph of the referenced blog.
