[1] Since its adoption by the United States Federal Council of Churches in 1942, it has had varied usage by congregations of many Christian traditions,[2][1] including Anglican,[3][4] Baptist,[5] Congregationalist,[6][7] Lutheran,[8] Mennonite,[9] Methodist,[2][10] Moravian,[11] Presbyterian,[12] and Reformed, among others.

[17] The Christian Flag was first conceived on September 26, 1897, at Brighton Chapel on Coney Island in Brooklyn, New York in the United States.

The superintendent of a Sunday school, Charles C. Overton, gave an impromptu lecture to the gathered students, because the scheduled speaker had failed to arrive for the event.

In 1907, Overton and Ralph Diffendorfer, secretary of the Methodist Young People's Missionary Movement, designed and began promoting the flag.

In the upper corner is a blue square, the color of the waters of baptism, emblematic of heaven, the home of the Christian; also a symbol of faith and trust.

[25] Mainline Protestant denominations in the United States accepted the flag first, and by the 1980s many institutions had described policies for displaying it inside churches.

Behold It, And Hail It With A Song, And Let The Voice Of Millions The Joyful Strain Prolong, To Every Clime And Nation, We Send It Forth Today; God Speed Its Glorious Mission, With Earnest Hearts We Pray.

Now Throw It To The Breeze, And May It Wave Triumphant O’er Land And Distant Seas, Till All The Wide Creation Upon Its Folds Shall Gaze, And All The World United, Our Loving Saviour Praise.
