What is spiritual adultery?
Spiritual adultery is the mixing of pagan practices or beliefs with New Testament Christianity. It occurs when religious organizations adopt elements from the pagan world and combine them with Christian truth, thereby prostituting the Word of God. Such a system adulterates the things of God and will face His judgment.
Les explains that the passage is not talking about physical adultery or immorality but about spiritual adultery. He defines it as religions or organizations taking from the pagan world and mixing it with New Testament Christianity. Any time paganism is mixed with Christianity, that prostitutes the truth of the Word of God. The 'whore' mentioned is not a woman of the street or evening but a system that has adulterated the things of God, and God will judge it. The text also says the kings of the earth committed fornication with this system, and the inhabitants of the earth were made drunk with the wine of her immorality.
