Sabbatarianism
Sabbatarianism advocates the observation of the Sabbath in Christianity, in keeping with the Ten Commandments. The observance of Sunday as a day of worship and rest is a form of first-day Sabbatarianism, a view which was historically heralded by nonconformist denominations, such as Congregationalists, Presbyterians, Methodists, Moravians, Quakers and Baptists, as well many Episcopalians.
