The Principle Of An International Auxiliary Language
Compiled by the Research Dept at the direction of the House of Justice, 1 Nov 79(?)
As to your suggestion regarding a more widespread use of Esperanto among the Bahá’ís as a medium of correspondence, Shoghi Effendi, as you know, has been invariably encouraging the believers, both in the East and in the West, to make an intensive study of that language, and to consider it as an important medium for the spread of the Cause in international circles. He has been specially urging the friends to have the Cause well represented in all Esperanto Congresses and associations, and by this means cultivate greater friendship and co-operation between them and the Esperantists.
But in this connection, he feels, he must make it clear that although the Cause views with much sympathy and appreciation the activities which the Esperantists are increasingly initiating for the spread of their language, yet it considers that the adoption of Esperanto by the entire world is by no means an inevitable fact. Neither Bahá’u’lláh, nor even ‘Abdu’l-Bahá, ever stated that Esperanto will be the international auxiliary language. The Master simply expressed the hope that it may, provided certain conditions were fulfilled, develop into such a medium.
