The Christian Flag is an ecumenical flag designed in the late 19th century to represent Christianity and Christendom. Baptist, Congregationalist, Lutheran, Mennonite, Methodist, Moravian, Presbyterian, and Reformed, among others.
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 shed on Calvary. The blue represents the waters of baptism as well as the faithfulness of Jesus. The white represents Jesus' purity. The dimensions of the flag and canton have no official specifications.
