In this “podclass” we’re going to see why Marcionism is the most prolific heresy today. Marcion was a second century heretic who taught that the God of the Old Testament was a different God from the New Testament. The section of St. Alphonsus Liguori’s book can be found here. Scroll down to #8 to read about Marcion.

Correction. I should have said the following: “St. Cyril of Alexandria taught that St. Paul wrote the New Testament book of Hebrews in Hebrew and St. Luke translated it to the Greek.”
