One who has abandoned his faith, political party, or cause.
[< Greek apostasis: revolt : apo–, away from + histanai, place.]
Having lost my faith in many things, abandoned many causes, and given up hope in many areas in a lot of areas — these works of man — I rely on faith in the works of God. Holiness, grace, and justice; the beauty of creation; the redemptive act of atonement performed by his son. Most of this site has nothing to do with faith or apostasy.
