I quote Wikipedia’s entry on Joachim of Fiore:
“Joachim’s theories were refuted by Thomas Aquinas in his Summa Theologica (written 1265-1274). In contrast, Dante situated Joachim in the Paradiso of his Divine Comedy (c. 1320).” … “Of importance is the fact that Joachim himself was never condemned as a heretic by the Church; rather, the ideas and movement surrounding him were condemned. Joachim the man was held in high regard during his lifetime.”
Prophecy never interested me before, but the state of the world has caused me to wonder about what might be coming. I agree with Stine’s comment at the end of his video.
