Theistic Satanism, otherwise referred to as spiritual Satanism, or devil worship, is one of two manifestations of Satanism, in contrast to nontheistic Satanism. It is an umbrella term for religious groups that consider Satan to objectively exist as a deity, supernatural entity, or spiritual being worthy of worship or reverence, whom individuals may believe in, contact, and convene with, in contrast to the atheistic archetype, metaphor, or symbol found in LaVeyan Satanism.
