The vision was enunciated by the Master in several Tablets and addresses. Its fullest expression occurs in a Tablet addressed by ‘Abdu’l-Bahá to Jane Elizabeth Whyte, wife of the former Moderator of the Free Church of Scotland. Mrs. Whyte was an ardent sympathizer of the Bahá’í teachings, had visited the Master in ‘Akká and would later make arrangements for the particularly warm reception that met Him in Edinburgh. Using the familiar metaphor of “candles”, ‘Abdu’l-Bahá wrote to Mrs. Whyte: O honored lady!... Behold how its [unity’s] light is now dawning upon the world’s darkened horizon. The first candle is unity in the political realm, the early glimmerings of which can now be discerned. The second candle is unity of thought in world undertakings, the consummation of which will erelong be witnessed. The third candle is unity in freedom which will surely come to pass. The fourth candle is unity in religion which is the corner-stone of the foundation itself, and which, by the power of God, will be revealed in all its splendor. The fifth candle is the unity of nations—a unity which in this century will be securely established, causing all the peoples of the world to regard themselves as citizens of one common fatherland. The sixth candle is unity of races, making of all that dwell on earth peoples and kindreds of one race. The seventh candle is unity of language, i.e., the choice of a universal tongue in which all peoples will be instructed and converse. Each and every one of these will inevitably come to pass, inasmuch as the power of the Kingdom of God will aid and assist in their realization.(144) While it will be decades—or perhaps a great deal longer—before the vision contained in this remarkable document is fully realized, the essential features of what it promised are now established facts throughout the world. In several of the great changes envisioned—unity of race and unity of religion—the intent of the Master’s words is clear and the processes involved are far advanced, however great may be the resistance in some quarters. To a large extent this is also true of unity of language. The need for it is now recognized on all sides, as reflected in the circumstances that have compelled the United Nations and much of the non-governmental community to adopt several “official languages”. Until a decision is taken by international agreement, the effect of such developments as the Internet, the management of air traffic, the development of technological vocabularies of various kinds, and universal education itself, has been to make it possible, to some extent, for English to fill the gap.
