The truth lies between these two positions. Almost every major founder belonged to a Christian congregation, although a sizable number of them were not committed Christians whose faith strongly influenced their political philosophy and actions.....
"...[M]any who played leading roles in the nation's Declaration of Independence", the Continental Congress, and the devising and ratification of the Constitution were devout Christians, as evident in their church attendance, commitment to prayer and Bible reading, belief in God's direction of earthly affairs, and conduct. Among others, these books discuss John Witherspoon, James Wilson, Samuel Adams, George Mason, Oliver Ellsworth, Patrick Henry, John Jay, Benjamin Rush, and Roger Sherman.
...[T]he faith of Congregationalist John Hancock, Quaker John Dickinson, Presbyterian Elias Boudinot, and Episcopalian Charles Pinckney, and others helped shape their political views, policies, and practice. Abigail Adams and Catholics Charles Carroll, Daniel Carroll, and John Carroll also were dedicated Christians. Moreover, Jay, Boudinot, Pinckney, and numerous other founders served as officers of the American Bible Society.
Even many of those often labeled as deists-Washington, Franklin, Adams, Jefferson, Madison, and Alexander Hamilton-do not fit the standard definition of deism, which asserts that after creating the world, God has had no more involvement with it. Deism views God as a transcendent first cause who is not immanent, triune, fully personal, or sovereign over human affairs. All of these founders, however, repeatedly discussed God's providence and frequently affirmed the value of prayer..... Those espousing this perspective believed in a powerful, benevolent Creator who established the laws by which the universe operates. They also believed that God answered prayer, that people best served Him by living a moral life, and that individuals would be rewarded or punished in the afterlife based on their earthly deeds. Only a few founders, most notably Thomas Paine and Ethan Allan, can properly be called deists.
Despite their theological differences, virtually all the founders maintained that morality depended on religion (which for them meant Christianity). They were convinced that their new republic could succeed only if its citizens were virtuous..... [more]Insight Scoop The Ignatius Press Blog: The Founders: How Christian Were They?
