Three Treatises on the Divine Images (St. Vladimir's Seminary Press Popular Patristics Series)

In AD 726, the Byzantine emperor ordered the destruction of all icons, or religious images, throughout the empire, and icons were subject to an imperial ban that was to last, with a brief remission, until AD 843. A defender of icons, St John of Damascus wrote three treatises against "those who attack the holy images." He differentiates between the veneration of icons, which is a matter of expressing honor, and idolatry, which is offering worship to something other than God.
