"We, therefore, following the royal pathway and the divinely inspired authority of our Holy Fathers and the traditions of the Catholic Church (for, as we all know, the Holy Spirit indwells her), define with all certitude and accuracy that just as the figure of the precious and life-giving Cross, so also the venerable and holy images, as well in painting and mosaic as of other fit materials, should be set forth in the holy churches of God, and on the sacred vessels and on the vestments and on hangings and in pictures both in houses and by the wayside, to wit, the figure of our Lord God and Saviour Jesus Christ, of our spotless Lady, the Mother of God, of the honourable Angels, of all Saints and of all pious people. For by so much more frequently as they are seen in artistic representation, by so much more readily are men lifted up to the memory of their prototypes, and to a longing after them; and to these should be given due salutation and honourable reverence, not indeed that true worship of faith which pertains alone to the divine nature; but to these, as to the figure of the precious and life-giving Cross and to the Book of the Gospels and to the other holy objects, incense and lights may be offered according to ancient pious custom. For the honour which is paid to the image passes on to that which the image represents, and he who reveres the image reveres in it the subject represented. For thus the teaching of our holy Fathers, that is the tradition of the Catholic Church, which from one end of the earth to the other hath received the Gospel, is strengthened. Thus we follow Paul, who spake in Christ, and the whole divine Apostolic company and the holy Fathers, holding fast the traditions which we have received. So we sing prophetically the triumphal hymns of the Church, 'Rejoice greatly, O daughter of Sion; Shout, O daughter of Jerusalem. Rejoice and be glad with all thy heart. The Lord hath taken away from thee the oppression of thy adversaries; thou art redeemed from the hand of thine enemies. The Lord is a King in the midst of thee; thou shalt not see evil any more, and peace be unto thee forever.'" - 7th Ecumenical Council, Decree of the Synod
