Sab"bat (?), n. [See Sabbath.] In mediæval demonology, the nocturnal
assembly in which demons and sorcerers were thought to celebrate their
orgies.
Sab`ba*ta"ri*an (?), n. [L. Sabbatarius: cf. F. sabbataire. See
Sabbath.] 1. One who regards and keeps the seventh day of the week as
holy, agreeably to the letter of the fourth commandment in the
Decalogue.
There were Christians in the early church who held this opinion, and
certain Christians, esp. the Seventh-day Baptists, hold it now.
