The African-Christian Church flag is based upon the regular Christian Church flag, but with Pan-African colours. Like the Hammons African-American flag, the colour red is conserved and Kwanzaa colours of red and black are included. Red is always conserved because the blood every Christian is always red, regardless of skin tone.
The popular Christian flag has a field of white with a blue canton and red cross. The unity point between these two flags is the red cross.
