The Christian flag is a banner that can be flown by any
Christian denomination, representing their faith and the
unity of all Christians. It features a red cross, the most
common and powerful symbol of Christianity colored for the
blood of its savior. It also contains a white field for biblical
purity, and a blue canton. It was conceived by an American,
Charles Overton, in 1897, but is now flown by Christians
around the world.
