Seven Ecumenical Councils in the context of "Union of Utrecht (Old Catholic)"

Iconolatry (Greek: εἰκών, eikon, 'picture or image', + λατρεία, latreia, 'veritable (full) worship or adoration') designates the idolatric worship or the adoration of icons. In the history of Christianity, iconolatry was mainly manifested in popular worship, as freedom of worship while others viewed it as superstitious belief in the divine nature of icons or deities. It was practiced as a focal point on icons, and other deities representing various saints, angels and the God. One of extreme practices of iconolatry was scraping parts of icons into the Holy Communion.

Iconolatry is the opposite of iconoclasm, and it also should not be confused with iconophilia, designating the moderate veneration of icons. Both extreme positions, iconolatry and iconoclasm, were rejected in 787 by the Second Council of Nicaea, being the seventh Ecumenical Council. The Council decided that holy icons should not be destroyed, as was advocated and practiced by the Byzantine iconoclasm, nor veritable (full) worshiped or adored (Greek: ἀληθινήν λατρείαν; Latin: veram latriam), as was practiced by iconolatry, but to be only venerated as symbolic representations of God, angels, or saints.
