The following text is based on Chaim Clorfene and Yakov Rogalsky's book "The Path of the Righteous Gentile"<ref>Clorfene, Chaim and Yaakov Rogalsky ''[http://moshiach.com/action/morality/introduction.php The Path of the Righteous Gentile: An Introduction to the Seven Laws of the Children of Noah]''. New York: Phillip Feldheim, 1987</ref>
The essence of the Seven Universal Laws is the prohibition against idolatry. One who worships another deity besides the Creator denies the essence of religion and rejects the entirety of the Seven Universal Laws. But one who guards himself against idolatry demonstrates belief in God and affirms the entirety of the Seven Universal Laws.<ref>Mishneh Torah, Laws of Idolatry, chapter 2, law 4</ref>
