The interest which the Bahá’ís have and should have in this language [Esperanto] is essentially because of the vital significance of the idea it represents rather than the belief in its inherent worth as a suitable and adequate international medium of expression.

The Bahá’ís indeed welcome Esperanto as the first experiment of its kind in modern times. They are in full sympathy with the Esperantists in so far as they stress the absolute necessity for the creation of an international language to be studied by all the peoples of the world in addition to their respective national languages.
