Definition: Idolatry, as an ancient religious concept in Christianity, involves worshiping a deity or icon from which one derives all their worship. The term "idolatry" has been used to describe any act that relies on the divine or on idols for its purpose. In the context of Christianity, idolatry can refer to the worship of false gods or the use of pagan symbols and images as a form of spiritual worship. In other words, idolatry involves worshiping a god who is not real or who does not exist in reality. It's important to note that idolatry is often associated with negative or harmful effects on individuals, such as religious persecution or destruction of the sacred sites where the idols are believed to be located.
