From ConservapediaGreek term for the rejection of the veneration of images (or icons). The practice of destroying religious images was justified as an interpretation of the Second Commandment and was supported by the Byzantine (or eastern Roman) emperor in the 8th century.
In either the year 726 or 730, Emperor Leo III banned all images of Christ that showed him in human form. The Iconoclasts argued that any image depicting God in human form either omits His divine nature or confuses it with His human nature.
The Seventh Ecumenical Council (787) defended image veneration believing that to venerate an image is to venerate not its substance but the shared likeness. An icon of Christ affirms the reality of the human and the divine.
