A mutual language will become the mightiest means of a universal progress toward the union of the East and the West. It will make the earth one home, and become the divine impulse for human advancement. It will upraise the standard of oneness in the world of humanity, and make the earth a universal commonwealth. It will be the cause of love between the children of men and create good fellowship between the various creeds.

(Abdul Baha, Divine Philosophy, p. 111)
