The Christian Flag is a flag designed in the early 20th century to represent all of Christianity and Christendom, and has been most popular among Christian 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 Jesus shed on Calvary. The blue represents the waters of baptism as well as the faithfulness of Jesus. The white represents Jesus' purity. In conventional vexillology, a white flag is linked to surrender, a reference to the Biblical description of Jesus' non-violence and surrender. The dimensions of the flag and canton have no official specifications.
