Aniconism is the absence of material representations of the natural and supernatural world in various cultures. Most denominations of Christianity have not generally practiced aniconism, or the avoidance or prohibition of these types of images, even dating back to early Christian art and architecture. Those in the faith have generally had an active tradition of making artwork and Christian media; depicting God, Jesus, The Holy Spirit, religious figures including saints and prophets, and other aspects of theology like The Trinity and Manus Dei.
There have however been periods of aniconism in Christian history, notably during the controversy of the Byzantine iconoclasm of the eighth century, and following the Protestant Reformation of the 16th century, when Calvinism in particular rejected all images in churches, and this practice continues today in some Reformed (Calvinist) churches, as well as some forms of fundamentalist Christianity. The Catholic Church has always defended the use of sacred images in churches, shrines, and homes, encouraging their veneration but condemning anyone who would worship them as if they were gods themselves.
