The Gods of the Nations

When ancient Israel encountered pagan nations worshiping their gods (and sometimes joined in themselves), what exactly were they worshiping? Are they fallen angels, demons, ancestors, the spirits of dead humans, or maybe even nothing at all? How did the early Church understand this worship? What is idolatry and how does it work? Do idolatry and paganism exist today? Fr. Andrew Stephen Damick and Fr. Stephen De Young look at ancient heathen religion and what it means in the Bible and for us today.
