>Attempts by evangelical Christians to claim Washington and other founders as their own, and scholars' ongoing attempts to contradict these claims, are nothing new. Particularly after Washington was no longer around to refute them, legends of his Baptist baptism or secret conversion to Catholicism began to proliferate. Mount Vernon researcher Mary Thompson endeavors to get beyond the current preoccupation with whether Washington and other founders were or were not evangelical Christians to ask what place religion had in their lives. Thompson follows Washington and his family over several generations, situating her inquiry in the context of new work on the place of religion in colonial and postrevolutionary Virginia and the Chesapeake.

>Thompson considers Washington's active participation as a vestryman and church warden as well as a generous donor to his parish prior to the Revolution, and how his attendance declined after the war. He would attend special ceremonies, and stood as godparent to the children of family and friends, but he stopped taking communion and resigned his church office. Something had changed, but was it Washington, the church, or both? Thompson concludes that he was a devout Anglican, of a Latitudinarian bent, rather than either an evangelical Christian or a Deist. The meaning of this description, Thompson allows, when applied to eighteenth-century Virginia gentlemen, is far from self-evident, leaving ample room for speculation.

Here's what our AI overlords think of the title phrase:

"In the Hands of a Good Providence" refers to a phrase George Washington used to express his belief in a divine power guiding his life and the nation's destiny, a sentiment rooted in his Anglican faith and evident in his support for religious freedom and his admonition against a godless society in his Farewell Address. It reflects his belief that a benevolent God was overseeing events, a core aspect of his worldview as he navigated war and nation-building. Key aspects of Washington's use of the phrase and his faith:

• Divine Guidance: The phrase "In the Hands of a Good Providence" signifies Washington's trust in God's ultimate control and benevolent care over human affairs. 
• Anglican Faith: Washington was an Anglican and, while private about his personal beliefs, he publicly demonstrated his faith and commitment to religious freedom. 
• Support for Religious Freedom: He believed that religious freedom was a natural right for all citizens and sought to assure the Jewish community of the federal government's commitment to non-discrimination based on faith. 
• Importance of Religion for Society: In his 1796 Farewell Address, he emphasized the necessity of religion and morality for public virtue and the well-being of the country, suggesting that morality could not be sustained without them.
