John 17: 21
"That they may all be one, just as you, Father, are in me, and I in you, that they also may be in us, so that the world may believe that you have sent me."
The History of the Y Logo
1881 - the Ninth Conference in London approves the first Y logo, which highlights Y values by featuring a reference to John 17:21 : "That they may all be one ... as We are one."
1891 - Luther H. Gulick, M.D., proposes a red triangle as the Y symbol. The equal sides of the triangle stands for " man's essential unity, body, mind and spirit, each being a necessary and eternal part of man, he being neither one alone..."
1895 - The annual convention of the U.S. and Canadian Ys authorizes adding the triangle to the old World Alliance Insignia.
1896 - The logo is simplified and a second ring is added. It is said the second ring represents friendship and love without end among individuals. This remains the Y's official emblem.
