The term Voodoo hoodoo is commonly used by Louisiana locals to describe our unique brand of New Orleans Creole Voodoo. It refers to a blending of religious and magickal elements. Voodoo is widely believed by those outside of the New Orleans Voodoo tradition to be separate from hoodoo magick. However, the separation of religion from magick did not occur in New Orleans as it did in other areas of the country. The magick is part of the religion; the charms are medicine and spiritual tools that hold the inherent healing mechanisms of the traditional religion and culture. Voodoo in New Orleans is a way of life for those who believe.
Still, there are those who separate Voodoo and hoodoo. Some hoodoo practitioners integrate elements of Voodoo, and some do not. Some incorporate elements of Catholicism or other Christian religious thought into their practice, while others do not. How much of the original religion a person decides to believe in and practice is left up to the individual. Some people don’t consider what they do religion at all, preferring to call it a spiritual tradition or African American folk magic. The term Voodoo hoodoo is in reference to the blend of the two aspects of the original religion as found in New Orleans Voodoo and as a way of life. A fellow New Orleans native and contemporary gris gris man Dr. John explains it this way:
In New Orleans, in religion, as in food or race or music, you can’t separate nothing from nothing. Everything mingles each into the other—Catholic saint worship with gris gris spirits, evangelical tent meetings with spiritual church ceremonies—until nothing is purely itself but becomes part of one fonky gumbo. That is why it is important to understand that in New Orleans the idea of Voodoo—or as we call it gris gris—is less a distinct religion than a way of life.~ Dr. John
