The deists have been misunderstood as Enlightenment thinkers who believed in an inactive deity. Instead, the deists were spiritually oriented people who believed God treated all his children fairly. Unlike the biblical God, the deist God did not punish entire nations with plagues, curse innocent people, or order the extermination of whole nations. In deism, for the first time in modern Western history, God "became" good.

The Spirituality of the English and American Deists: How God Became Good explores how the English deists were especially important because they formulated the arguments that most of the later deists accepted. Half of the English deists claimed they were advocating the Christianity Jesus taught before his later followers perverted his teachings. Joseph Waligore call these deists Jesus-centered deists.

Ben Franklin, Thomas Jefferson, and John Adams studied these Jesus-centered deists and had similar beliefs. While some of the most prominent American Founders were deists, deism had little or no influence on the religious parts of the Constitution and the First Amendment.

Deism did not die out at the end of the Enlightenment. Instead, under different names and forms it has continued to be a significant religious force. Informed observers even think a deistic spiritual outlook is the most popular religious or spiritual outlook in contemporary America.
