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 scriptural account of creation in Genesis wherein an "evening and morning" established a day, predating the giving of the Ten Commandments (thus the command to "remember" the sabbath). Seventh-day Sabbatarianism was the practice of all or most of the early Christian church through the 4th century.[1][2] The seventh day of the week is recognized in many languages and calendars as Sabbath, and is still observed as such in modern Judaism.
