Socinianism \So*cin"i*an*ism\, n. (Eccl. Hist.)
   The tenets or doctrines of Faustus Socinus, an Italian
   theologian of the sixteenth century, who denied the Trinity,
   the deity of Christ, the personality of the Devil, the native
   and total depravity of man, the vicarious atonement, and the
   eternity of future punishment. His theory was, that Christ
   was a man divinely commissioned, who had no existence before
   he was conceived by the Virgin Mary; that human sin was the
   imitation of Adam's sin, and that human salvation was the
   imitation and adoption of Christ's virtue; that the Bible was
   to be interpreted by human reason; and that its language was
   metaphorical, and not to be taken literally.
