Impiety is a perceived lack of proper respect for something considered sacred. Impiety is often closely associated with sacrilege, though it is not necessarily a physical action. Impiety cannot be associated with a cult, as it implies a larger belief system was disrespected. One of the Pagan objections to Christianity was that, unlike other mystery religions, early Christians refused to cast a pinch of incense before the images of the gods, an impious act in their eyes. Impiety in ancient civilizations was a civic concern, rather than solely religious. It was believed that impious actions such as disrespect towards sacred objects or priests could bring down the wrath of the gods.
