1. You could look at the writings of the Doctors of the Church like St. Augustine (civ. Dei 21.3.1; ench. 93) or St. Thomas Aquinas (STh., Supplementum q.69 a.2) who clearly believed there ARE souls in Hell
2. You could look to the saintly testimony of saints like St. Drithelm or the visionaires of Our Lady of Fatima that were shown damned souls in Hell.
3. You could also consider the fact that it is a ʻDe Fideʻ teaching that "The souls of those who die in the condition of personal grievous sin enter Hell."(Ott, L. 1957)
It would logically flow that to believe that NO ONE is in hell is to believe that NO ONE dies in the condition of grievous personal sin. That is not a logical premise. period.
4. Lastly, and most definitively, you could look to the very words of Christ in verses like Mt 25:34 ; Mt 7:13–14 ; Lk 13:23-24, and many others. As an example lets take a look specifically look at Lk 13:23-24
“And a certain man said to him: Lord, are they few that are saved? But he said to them: Strive to enter by the narrow gate: for many, I say to you, shall seek to enter and shall not be able.”
If no one is in Hell then why ʻstriveʻ? Did Jesus lie when he says "for many, I say to you, shall seek to enter and shall not be able"?
Certainly it should be clear that we cant discard the teachings St. Augustine, St. Thomas Aquinas, visionary Saints like St. Drithelm, De fide teachings of the Church, Our Lady of Fatima, and the very Words of Christ for a universalist view that Hell is empty!
Hell is real. Grievous sin can you send there. Souls have already been sent there. DON’T go to Hell! Go to Heaven!
