The term "Harlot Church" is not a specific biblical phrase, but it is often used in theological discussions to describe a church or religious institution that is perceived to be unfaithful to God, particularly in terms of spiritual idolatry or moral compromise. The imagery of a harlot or prostitute frequently appears in the Bible to depict unfaithfulness, particularly in the context of Israel's relationship with God. For example, in the prophetic books, Israel is often portrayed as a harlot when she turns to worship other gods or engages in practices contrary to the covenant established with Yahweh (see Ezekiel 16; Hosea 1-3).One of the most vivid representations of this concept is found in the Book of Revelation, particularly in Revelation 17, where the "Great Harlot" is described as a city that embodies corruption and apostasy, symbolizing the ultimate rebellion against God. The passage depicts her as sitting on many waters, representing nations and peoples, and she is associated with the "kings of the earth" who indulge in her immoralities (Revelation 17:1-2). This imagery serves as a warning against compromising the faith and highlights the dangers of aligning with worldly values over divine commandments. Thus, the term "Harlot Church" can be used to critique any church or organization perceived to have strayed from its foundational truths and moral integrity, aligning itself instead with secular or sinful practices.
