Vodouists believe in a distant and unknowable Supreme Creator, Bondye (derived from the French term Bon Dieu, meaning "good God"). According to Vodouists, Bondye does not intercede in human affairs, and thus they direct their worship toward spirits subservient to Bondye, called loa. Every loa is responsible for a particular aspect of life, with the dynamic and changing personalities of each loa reflecting the many possibilities inherent to the aspects of life over which they preside. To navigate daily life, vodouists cultivate personal relationships with the loa through the presentation of offerings, the creation of personal altars and devotional objects, and participation in elaborate ceremonies of music, dance, and spirit possession.
Vodou originated in the Caribbean and developed in the French Empire in the 18th century among West African slaves when African religious practice was actively suppressed, and enslaved Africans were forced to convert to Christianity. Religious practices of contemporary Vodou are descended from, and closely related to, West African Vodun as practiced by the Fon and Ewe. Vodou also incorporates elements and symbolism from other African peoples including the Yoruba and Kongo; as well as Taíno religious beliefs, Roman Catholicism, and European spirituality including mysticism, Freemasonry, and other influences.
In Haiti, whereas a very small number of Roman Catholics combine their faith with aspects of Vodou, this practice is denounced as diabolical by virtually all Haitian Protestants.
