The subject of this thesis is the history of the iconoclastic controversy that originated in the 8th century Byzantine church. Christian art flowered in the time of the Emperor Justinian and in the 8th century the iconoclastic controversy arose. The full-dress iconoclastic controversy started at the beginning of the 8th century, was dealt with by successive General Councils until the matter was solved when the 7th Nicene council of 787 approved the veneration of images. These became idolatry, threw church and society into chaos so that the Pope and the emporer and their supporters over the course of two centuries developed their own Christologies. At that time images were at the heart of the people(Minjung)’s faith. There is always a tendency for religious feelings to be transformed by images.This writer in concentrating on the 8th century controversy has reviewed its historical background, occasion and results and has attempted to deal with the question of images in relation to present day church worship. Idolatry through worship of symbols finds fulfillment in Eucharistic theology for that visualizes the presence of Christ.
