What is common to all who are devoted to one or another of the world's religious systems is the conviction that it is through the Divine Revelation that the soul comes in touch with the world of God, and that it is this relationship which gives real meaning to life. Some of the most important passages in Bahá'u'lláh's writings are those which discuss at length the nature and role of those who are the channels of this Revelation, the Messengers or "Manifestations of God." A recurrent analogy found in these passages is that of the physical sun. While the latter shares certain characteristics of the other bodies in the solar system, it differs from them in that it is, in itself, the source of the system's light. The planets and moons reflect light whereas the sun emits it as an attribute inseparable from its nature. The system revolves around this focal point, each of its members influenced not only by its particular composition, but by its relationship to the source of the system's light.(42)
In the same way, Bahá'u'lláh asserts, the human personality which the Manifestation of God shares with the rest of the race is differentiated from others in a way that fits it to serve as the channel or vehicle for the Revelation of God. Apparently contradictory references to this dual station, attributed, for example, to Christ,(43) have been among the many sources of religious confusion and dissension throughout history. Bahá'u'lláh says on the subject:
Throughout history, the conviction of believers that the Founder of their own religion occupied a unique station has had the effect of stimulating intense speculation on the nature of the Manifestation of God. Such speculation has, however, been severely hampered by the difficulties of interpreting and resolving the allegorical allusions in past scriptures. The attempt to crystallize opinion in the form of religious dogma has been a divisive rather than unifying force in history. Indeed, despite the enormous energy devoted to theological pursuits -- or perhaps because of it -- there are today profound differences among Muslims as to the precise station of Muhammad, among Christians as to that of Jesus, and among Buddhists with respect to the Founder of their own religion. As is all too apparent, the controversies created by these and other differences within any one given tradition have proven at least as acute as those separating that tradition from its sister faiths.
Particularly important to an understanding of Bahá'u'lláh's teachings on the unity of religions, therefore, are His statements about the station of the successive Messengers of God and the functions performed by them in the spiritual history of humankind:
[The] Manifestations of God have each a twofold station. One is the station of pure abstraction and essential unity. In this respect, if thou callest them all by one name, and dost ascribe to them the same attributes, thou hast not erred from the truth ....
The other station is the station of distinction, and pertaineth to the world of creation, and to the limitations thereof. In this respect, each Manifestation of God hath a distinct individuality, a definitely prescribed mission, a predestined revelation, and specially designated limitations. Each one of them is known by a different name, is characterized by a special attribute, fulfills a definite mission ...
Viewed in the light of their second station ... they manifest absolute servitude, utter destitution, and complete self-effacement. Even as He saith: "I am the servant of God. I am but a man like you." ...
Were any of the all-embracing Manifestations of God to declare: "I am God," He, verily, speaketh the truth, and no doubt attacheth thereto. For ... through their Revelation, their attributes and names, the Revelation of God, His names and His attributes, are made manifest in the world .... And were any of them to voice the utterance, "I am the Messenger of God," He, also, speaketh the truth, the indubitable truth .... Viewed in this light, they are all but Messengers of that ideal King, that unchangeable Essence .... And were they to say, "We are the Servants of God," this also is a manifest and indisputable fact. For they have been made manifest in the uttermost state of servitude, a servitude the like of which no man can possibly attain ....(45)
Thus it is that whatsoever be their utterance, whether it pertain to the realm of Divinity, Lordship, Prophethood, Messengership, Guardianship, Apostleship, or Servitude, all is true, beyond the shadow of a doubt. Therefore these sayings ... must be attentively considered, that the divergent utterances of the Manifestations of the Unseen and Day Springs of Holiness may cease to agitate the soul and perplex the mind.(46)
Implicit in these paragraphs is a perspective which represents the most challenging feature of Bahá'u'lláh's exposition of the function of the Manifestation of God. Divine Revelation is, He says, the motive power of civilization. When it occurs, its transforming effect on the minds and souls of those who respond to it is replicated in the new society that slowly takes shape around their experience. A new center of loyalty emerges that can win the commitment of peoples from the widest range of cultures; music and the arts seize on symbols that mediate far richer and more mature inspirations; a radical redefinition of concepts of right and wrong makes possible the formulation of new codes of civil law and conduct; new institutions are conceived in order to give expression to impulses of moral responsibility previously ignored or unknown: "He was in the world, and the world was made by him ... "(47) As the new culture evolves into a civilization, it assimilates achievements and insights of past eras in a multitude of fresh permutations. Features of past cultures that cannot be incorporated atrophy or are taken up by marginal elements among the population. The Word of God creates new possibilities within both the individual consciousness and human relationships.
Eventually, as an ever-evolving civilization exhausts its spiritual sources, a process of disintegration sets in, as it does throughout the phenomenal world. Turning again to analogies offered by nature, Bahá'u'lláh compares this hiatus in the development of civilization to the onset of winter. Moral vitality diminishes, as does social cohesion. Challenges which would have been overcome at an earlier age, or been turned into opportunities for exploration and achievement, become insuperable barriers. Religion loses its relevance, and experimentation becomes increasingly fragmented, further deepening social divisions. Increasingly, uncertainty about the meaning and value of life generates anxiety and confusion. Speaking about this condition in our own age Bahá'u'lláh says:
When each of the Divine impulses has fulfilled itself, the process recurs. A new Manifestation of God appears with the fuller measure of Divine inspiration for the next stage in the awakening and civilizing of humankind:
Until a section of humanity begins to respond to the new Revelation, and a new spiritual and social paradigm begins to take shape, people subsist spiritually and morally on the last traces of earlier Divine endowments. The routine tasks of society may or may not be done; laws may be obeyed or flouted; social and political experimentation may flame up or fail; but the roots of faith -- without which no society can indefinitely endure -- have been exhausted. At the "end of the age," at the "end of the world," the spiritually minded begin to turn again to the Creative source. However clumsy or disturbing the process may be, however inelegant or unfortunate some of the options considered, such searching is an instinctive response to the awareness that an immense chasm has opened in the ordered life of humankind.(53) The effects of the new Revelation, Bahá'u'lláh says, are universal, and not limited to the life and teachings of the Manifestation of God Who is the Revelation's focal point. Though not understood, these effects increasingly permeate human affairs, revealing the contradictions in popular assumptions and in society, and intensifying the search for understanding.
The succession of the Manifestations is an inseparable dimension of existence, Bahá'u'lláh declares, and will continue throughout the life of the world: "God hath sent down His Messengers to succeed to Moses and Jesus, and He will continue to do so till 'the end that hath no end' ..."(54)
