"Congress shall make no law respecting an establishment of religion, or prohibiting the free exercise thereof; or abridging the freedom of speech, or of the press; or the right of the people peaceably to assemble, and to petition the Government for a redress of grievances."
For these American patriots, even the forms of Anglican services were in doubt, since the Prayer Book rites of Matins, Evensong and Holy Communion, all included specific prayers for the British Royal Family. Consequently, the conclusion of the War of Independence eventually resulted in the creation of two new Anglican churches, the Episcopal Church in the United States in those states that had achieved independence
Embracing the symbols of the British presence in the American colonies, such as the monarchy, the episcopate, and even the language of the Book of Common Prayer, the Church of England almost drove itself to extinction during the upheaval of the American Revolution. More than any other denomination, the War of Independence internally divided both clergy and laity of the Church of England in America, and opinions covered a wide spectrum of political views: patriots, conciliators, and loyalists. While many Patriots were suspicious of Loyalism in the church, about three-quarters of the signers of the Declaration of Independence were nominally Anglican laymen, including Thomas Jefferson, William Paca, and George Wythe. It was often assumed that persons considered "High Church" were Loyalists, whereas persons considered "Low Church" were Patriots; assumptions with possibly dangerous implications for the time.
Within the United States, the model of Congregational churches was carried by migrating settlers from New England into New York, then into the Old North West, and further. With their insistence on independent local bodies, they became important in many social reformmovements, including abolitionism, temperance, and women's suffrage. Modern Congregationalism in the United States is largely split into three bodies: the United Church of Christ, the National Association of Congregational Christian Churches and the Conservative Congregational Christian Conference, which is the most theologically conservative.
