A branch of evangelical Christians who take the Bible literally. They believe that one of the most important of God's commands is to "be fruitful and multiply" (it's written twice!). Quiverfull families have as many children in the least amount of time that is humanly possible. The quiverfull mission is to repopulate the world with white Christians, and the movement is one of the fastest growing segments of Dominionist Christians.
Did you see that quiverfull family on TLC last night? They had, like, twenty kids!
