On some of the oldest Masonic charts, the rainbow is one of the symbols used in connection with fraternal life. Its symbolism and colors have been used as a basis for a ritual. Rev. Sexson decided to associate the name of the organization with the rainbow because rainbows represent the first visible sign that God gave to His creatures. The International Order of the Rainbow for Girls selects the girlhood of a country as a medium through which God fulfills His promise.
