Sabbath in seventh-day churches

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.

Catholic, Orthodox, and most Protestant denominations believe the Mosaic Law to be superseded. Yet it is only in the west that some Christians describe the sabbath as being transferred to Sunday, the first day of the week, merged with the Lord's Day and the day of Christ's resurrection, forming (in some traditions) a "Christian Sabbath".
