seventh-day Sabbatarianism

The seventh-day Sabbath, observed from Friday sunset to Saturday sunset, is an important part of the beliefs and practices of seventh-day churches. These churches emphasize biblical references such as the ancient Hebrew practice of beginning a day at sundown, and the Genesis creation narrative wherein an "evening and morning" established a day, predating the giving of the Ten Commandments (thus the command to "remember" the sabbath). The seventh day of the week is recognized as Sabbath in many languages, calendars, and doctrines, including those of Catholic and Orthodox churches. It is still observed in modern Judaism in relation to Mosaic Law.
