WordNet (r) 3.0 (2006):

predestination
    n 1: previous determination as if by destiny or fate
    2: (theology) being determined in advance; especially the
       doctrine (usually associated with Calvin) that God has
       foreordained every event throughout eternity (including the
       final salvation of mankind) [syn: predestination,
       foreordination, preordination, predetermination]

The Devil's Dictionary (1881-1906):

PREDESTINATION, n.  The doctrine that all things occur according to
programme.  This doctrine should not be confused with that of
foreordination, which means that all things are programmed, but does
not affirm their occurrence, that being only an implication from other
doctrines by which this is entailed.  The difference is great enough
to have deluged Christendom with ink, to say nothing of the gore.
With the distinction of the two doctrines kept well in mind, and a
reverent belief in both, one may hope to escape perdition if spared.
