Quiverfull takes its name from Psalm 127: "Like arrows in the hands of a warrior are sons born in one's youth. Blessed is the man whose quiver is full of them.
Quiverfull advocates Rick and Jan Hess, authors of 1990's "A Full Quiver: Family Planning and the Lordship of Christ," envision the worldly gains such a method could bring, if more Christians began producing "full quivers" of "arrows for the war": control of both houses of Congress, the "reclamation" of sinful cities like San Francisco and massive boycotts of companies that do not comply with conservative Christian mores. "If the body of Christ had been reproducing as we were designed to do," the Hesses write, "we would not be in the mess we are today." Nancy Campbell, author of another movement book from 2003 called "Be Fruitful and Multiply," exhorts Christian women to do just that with promises of spiritual glory. "Oh what a vision," she writes, "to invade the earth with mighty sons and daughters who have been trained and prepared for God's divine purposes."
