<P> The seventh - day Sabbath, observed from Friday evening to Saturday evening (exact start and ending times varying from group to group), 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). They hold that the Old and New Testament show no variation in the doctrine of the Sabbath on the seventh day . Saturday, or the seventh day in the weekly cycle, is the only day in all of scripture designated using the term Sabbath . The seventh day of the week is recognized as Sabbath in many languages, calendars, and doctrines, including those of Catholic, Lutheran, and Orthodox churches . It is still observed in modern Judaism in relation to Mosaic Law . In addition, the Orthodox Tewahedo Churches uphold Sabbatarianism, observing the Sabbath on Saturday, in addition to the Lord's Day on Sunday . </P> <P> Catholic, Orthodox, and some Protestant denominations observe the Lord's Day on Sunday and hold that the Saturday Sabbath is no longer binding for Christians . On the other hand, Congregationalists, Presbyterians, Methodists, and Baptists, as well as many Episcopalians, have historically espoused the view of first - day Sabbatarianism, describing the Sabbath as being transferred to the Lord's Day (Sunday), the first day of the week, merged with the day of Christ's resurrection, forming the Christian Sabbath . </P>
