Arminian \Ar*min"i*an\, n. (Eccl. Hist.)
   One who holds the tenets of Arminius, a Dutch divine (b.
   1560, d. 1609).

   Note: The Arminian doctrines are: 1. Conditional election and
         reprobation, in opposition to absolute predestination.
         2. Universal redemption, or that the atonement was made
         by Christ for all mankind, though none but believers
         can be partakers of the benefit. 3. That man, in order
         to exercise true faith, must be regenerated and renewed
         by the operation of the Holy Spirit, which is the gift
         of God. 4. That man may resist divine grace. 5. That
         man may relapse from a state of grace.
