Definition of Sabbatarianism

In Christianity, the Sabbath is a weekly religious day of rest as ordained by one of the Ten Commandments: the third commandment by Roman Catholic and Lutheran numbering, and the fourth by Eastern Orthodox and other Protestant numbering. The practice is inherited from Judaism, the parent religion of Christianity; the Hebrew word שַבָת ("šabbat" , read in English as shabbat) means "the [day] of rest (or ceasing)" and entails a ceasing or resting from labor. The institution of the Old Testament Sabbath, a "perpetual covenant ... [for] the people of Israel" , was in respect for the day during which God rested after having completed the Creation in six days (, ).
