The Bearers of the Trust of God are made manifest unto the peoples of the earth as the Exponents of a new Cause and the Revealers of a new Message. Inasmuch as these Birds of the celestial Throne are all sent down from the heaven of the Will of God, and as they all arise to proclaim His irresistible Faith, they, therefore, are regarded as one soul and the same person. For they all drink from the one Cup of the love of God, and all partake of the fruit of the same Tree of Oneness.
These 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. Even as He hath revealed: "No distinction do We make between any of His Messengers." For they, one and all, summon the people of the earth to acknowledge the unity of God, and herald unto them the Kawthar of an infinite grace and bounty. They are all invested with the robe of prophethood, and are honored with the mantle of glory. Thus hath Muhammad, the Point of the Qur'án, revealed: "I am all the Prophets." Likewise, He saith: "I am the first Adam, Noah, Moses, and Jesus." Similar statements have been made by Imam Ali. Sayings such as these, which indicate the essential unity of those Exponents of Oneness, have also emanated from the Channels of God's immortal utterance, and the Treasuries of the gems of Divine knowledge, and have been recorded in the Scriptures. These Countenances are the recipients of the Divine Command, and the Day Springs of His Revelation. This Revelation is exalted above the veils of plurality and the exigencies of number. Thus He saith: "Our Cause is but One." Inasmuch as the Cause is one and the same, the Exponents thereof also must needs be one and the same….
It is clear and evident to thee that all the Prophets are the Temples of the Cause of God, Who have appeared clothed in divers attire. If thou wilt observe with discriminating eyes, thou wilt behold Them all abiding in the same tabernacle, soaring in the same heaven, seated upon the same throne, uttering the same speech, and proclaiming the same Faith. Such is the unity of those Essences of Being, those Luminaries of infinite and immeasurable splendor! Wherefore, should one of these Manifestations of Holiness proclaim saying: "I am the return of all the Prophets," He, verily, speaketh the truth. In like manner, in every subsequent Revelation, the return of the former Revelation is a fact, the truth of which is firmly established....
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, fulfils a definite mission, and is entrusted with a particular Revelation. Even as He saith: "Some of the Apostles We have caused to excel the others. To some God hath spoken, some He hath raised and exalted. And to Jesus, Son of Mary, We gave manifest signs, and We strengthened Him with the Holy Spirit."
It is because of this difference in their station and mission that the words and utterances flowing from these Well Springs of Divine knowledge appear to diverge and differ. Otherwise, in the eyes of them that are initiated into the mysteries of Divine wisdom, all their utterances are, in reality, but the expressions of one Truth. As most of the people have failed to appreciate those stations to which We have referred, they, therefore, feel perplexed and dismayed at the varying utterances pronounced by Manifestations that are essentially one and the same.
