Viewing these periods of Bahá’í history as the constituents of a single entity, we note the chain of events proclaiming successfully the rise of a Forerunner, the Mission of One Whose advent that Forerunner had promised, the establishment of a Covenant generated through the direct authority of the Promised One Himself, and lastly the birth of a System which is the child sprung from both the Author of the Covenant and its appointed Center. We observe how the Báb, the Forerunner, announced the impending inception of a divinely-conceived Order, how Bahá’u’lláh, the Promised One, formulated its laws and ordinances, how ‘Abdu’l-Bahá, the appointed Center, delineated its features, and how the present generation of their followers have commenced to erect the framework of its institutions. We watch, through these periods, the infant light of the Faith diffuse itself from its cradle, eastward to India and the Far East, westward to the neighboring territories of ‘Iráq, of Turkey, of Russia, and of Egypt, travel as far as the North American continent, illuminate subsequently the major countries of Europe, envelop with its radiance, at a later stage, the Antipodes, brighten the fringes of the Arctic, and finally set aglow the Central and South American horizons. We witness a corresponding increase in the diversity of the elements within its fellowship, which from being confined, in the first period of its history, to an obscure body of followers chiefly recruited from the ranks of the masses in _Sh_í’ah Persia, has expanded into a fraternity representative of the leading religious systems of the world, of almost every caste and color, from the humblest worker and peasant to royalty itself. We notice a similar development in the extent of its literature—a literature which, restricted at first to the narrow range of hurriedly transcribed, often corrupted, secretly circulated, manuscripts, so furtively perused, so frequently effaced, and at times even eaten by the terrorized members of a proscribed sect, has, within the space of a century, swelled into innumerable editions, comprising tens of thousands of printed volumes, in diverse scripts, and in no less than forty languages, some elaborately reproduced, others profusely illustrated, all methodically and vigorously disseminated through the agency of world-wide, properly constituted and specially organized committees and Assemblies. We perceive a no less apparent evolution in the scope of its teachings, at first designedly rigid, complex and severe, subsequently recast, expanded, and liberalized under the succeeding Dispensation, later expounded, reaffirmed and amplified by an appointed Interpreter, and lastly systematized and universally applied to both individuals and institutions. We can discover a no less distinct gradation in the character of the opposition it has had to encounter—an opposition, at first kindled in the bosom of _Sh_í’ah
