Religious images in Christian theology have a role within the liturgical and devotional life of adherents of certain Christian denominations. The use of religious images has often been a contentious issue in Christian history. Concern over idolatry is the driving force behind the various traditions of aniconism in Christianity.
In the early Church, Christians used the Ichthys (fish) symbol to identify Christian places of worship and Christian homes. The Synod of Elvira (306 AD - 312 AD) "prohibited the exhibition of images in churches". However, since the 3rd century AD, images have been used within Christian worship within parts of Christendom, although some ancient Churches, such as the Church of the East, have apparently long traditions of not using images. However, there is also both literary and archaeological evidence for the early presence of images in the Church of the East tradition.
