The oneness of humanity and its happiness are dependent on the equality of man and woman

And let it be known once more that until woman and man recognize and realize equality, social and political progress here or anywhere will not be possible. For the world of humanity consists of two parts or members: one is woman; the other is man. Until these two members are equal in strength, the oneness of humanity cannot be established, and the happiness and felicity of mankind will not be a reality. God willing, this is to be so.(The Promulgation of Universal Peace, p. 76)
