Related terms to henotheism are monolatrism and kathenotheism. The latter term is an extension of "henotheism", from ("kath' hena theon") — "one god at a time". Henotheism refers to a pluralistic theology wherein different deities are viewed to be of a unitary, equivalent divine essence. Some scholars prefer the term monolatry to henotheism, to discuss religions where a single god is central, but the existence or the position of other gods is not denied. Another term related to henotheism is "equitheism", referring to the belief that all gods are equal.
