Definition of glassite

• n. - A member of a Scottish sect, founded in the 18th century by John Glass, a minister of the Established Church of Scotland, who taught that justifying faith is "no more than a simple assent to the divine testimone passively recived by the understanding." The English and American adherents of this faith are called Sandemanians, after Robert Sandeman, the son-in-law and disciple of Glass.
