Answer:Religion played a major role in the American Revolution by offering a moral sanction for opposition to the British--an assurance to the average American that revolution was justified in the sight of God. As a recent scholar has observed, "by turning colonial resistance into a righteous cause, and by crying the message to all ranks in all parts of the colonies, ministers did the work of secular radicalism and did it better."
The Revolution strengthened millennialist strains in American theology. At the beginning of the war some ministers were persuaded that, with God's help, America might become "the principal Seat of the glorious Kingdom which Christ shall erect upon Earth in the latter Days." Victory over the British was taken as a sign of God's partiality for America and stimulated an outpouring of millennialist expectations--the conviction that Christ would rule on earth for 1,000 years. This attitude combined with a groundswell of secular optimism about the future of America to create the buoyant mood of the new nation that became so evident after Jefferson assumed the presidency in 1801.
