The Christian Flag is a flag designed in the early 20th century to represent all of Christianity (see also Christendom), but it has been adopted mainly by Protestant churches in North America, Africa and Latin America. The flag has a white field, with a red Latin cross inside a blue canton. The shade of red on the cross symbolizes the blood that Jesus Christ shed on Calvary, the blue is a picture of the royalty of Jesus Christ as King of Kings, and the white represents the purity of Jesus Christ. The dimensions of the flag and canton have no official specifications.
