- This word (from the Greek eikōn, meaning "image," and klastēs, meaning "breaker") refers to a movement that began in the eighth century in the Eastern Churches in opposition to the use of images in worship. The Second Council of Nicaea (787) rejected iconoclasm and approved the veneration of icons. (See CCC 2131-2132)
