"Whore of Babylon"
Sacred prostitution, temple prostitution, cult prostitution,[1] and religious prostitution are general terms for a sexual rite consisting of sexual intercourse or other sexual activity performed in the context of religious worship, perhaps as a form of fertility rite or divine marriage (hieros gamos). Some scholars prefer the term sacred sex to sacred prostitution in cases where payment for services was not involved.
