Supralapsarian \Su`pra*lap*sa"ri*an\, n. [Supra- + lapse: cf. F.
supralapsaire.] (Eccl. Hist.)
One of that class of Calvinists who believed that God's
decree of election determined that man should fall, in order
that the opportunity might be furnished of securing the
redemption of a part of the race, the decree of salvation
being conceived of as formed before or beyond, and not after
or following, the lapse, or fall. Cf. {Infralapsarian}.
