Sabbatarians

Sabbatarianism is a view within Christianity that advocates the observation of the Sabbath, in keeping with the Ten Commandments. Its historical origins lie in early Christianity, later in the Eastern Church and Irish Church, and then in Puritan Sabbatarianism, which delineated precepts for keeping Sunday, the Lord's Day, holy in observance of Sabbath commandment principles. This observance of Sunday as a day of worship and rest is the purest form of first-day Sabbatarianism, a view which was historically heralded by nonconformist denominations, such as Congregationalists, Presbyterians, Methodists, and Baptists, as well as many Episcopalians; although its impact diminished in popular culture, traces and influences remain today, e.g. Sunday laws.

Seventh-day Sabbatarianism is a movement that generally embraces a literal reading of the Sabbath commandment that provides for both worship and rest on the seventh day of the week. Seventh-day Baptists leave most other Sabbath considerations of observance to individual conscience. The Seventh-day Adventist Church and Church of God (Seventh Day) have similar views, but maintain the original, scriptural duration as Friday sunset through Saturday sunset. The Orthodox Tewahedo Churches in Eritrea and Ethiopia, observe the seventh-day Sabbath, as well as Sunday as the Lord's Day. Likewise, the Coptic Church, another Oriental Orthodox body, "stipulates that the seventh-day Sabbath, along with Sunday, be continuously regarded as a festal day for religious celebration."
