For years I have been curious about Zoroastrianism. It is not one of the 3 Abrahamic religions, but it developed nearly simultaneoulsy with Judaism. Zoroastrianism is not considered by Catholics to be a revealed faith. Something that strikes me, though, is its teaching that Hell is a temporary state. It also teaches the coming of a general resurrection day, at which time those who have been punished and cleansed in Hell will be given new bodies and enter into Heaven. That sounds alot like Purgatory to me.
There is no record of Jesus ever being exposed to Zoroaster’s teachings, so perhaps this is merely a coincidence. Still, I wonder if it did not somehow influence early Church thinking, considering that in neither Judaism nor Islam is Hell temporary. Nor do they hold to the existence of Purgatory.
It’s interesting to think about.
