“To every discerning and illuminated heart it is evident that God, the unknowable Essence, the Divine Being, is immensely exalted beyond every human attribute, such as corporeal existence, ascent and descent, egress and regress. Far be it from His glory that human tongue should adequately recount His praise, or that human heart comprehend His fathomless mystery. He is, and hath ever been, veiled in the ancient eternity of His Essence, and will remain in His Reality everlastingly hidden from the sight of men….
The door of the knowledge of the Ancient of Days being thus closed in the face of all beings, the Source of infinite grace … hath caused those luminous Gems of Holiness [Manifestations of God, including Bahá’u’lláh, The Báb, Muhammad, Jesus Christ, Moses, Zoroaster, Buddha, and Krishna] to appear out of the realm of the spirit, in the noble form of the human temple, and be made manifest unto all men, that they may impart unto the world the mysteries of the unchangeable Being, and tell of the subtleties of His imperishable Essence.
These sanctified Mirrors, these Day Springs of ancient glory, are, one and all, the Exponents on earth of Him Who is the central Orb of the universe, its Essence and ultimate Purpose. From Him proceed their knowledge and power; from Him is derived their sovereignty. The beauty of their countenance is but a reflection of His image, and their revelation a sign of His deathless glory. They are the Treasuries of Divine knowledge, and the Repositories of celestial wisdom. Through them is transmitted a grace that is infinite, and by them is revealed the Light that can never fade…. These Tabernacles of Holiness, these Primal Mirrors which reflect the light of unfading glory, are but expressions of Him Who is the Invisible of the Invisibles. By the revelation of these Gems of Divine virtue all the names and attributes of God, such as knowledge and power, sovereignty and dominion, mercy and wisdom, glory, bounty, and grace, are made manifest.
These attributes of God are not, and have never been, vouchsafed specially unto certain Prophets, and withheld from others. Nay, all the Prophets of God, His well-favored, His holy and chosen Messengers are, without exception, the bearers of His names, and the embodiments of His attributes. They only differ in the intensity of their revelation, and the comparative potency of their light.”
(Bahá’u’lláh, Gleanings from the Writings of Bahá’u’lláh, p. 46)
“Unto this subtle, this mysterious and ethereal Being [the Manifestation of God, or Divine Teacher or Messenger] He [God] hath assigned a twofold nature; the physical, pertaining to the world of matter, and the spiritual, which is born of the substance of God Himself. He hath, moreover, conferred upon Him a double station. The first station, which is related to His innermost reality, representeth Him as One Whose voice is the voice of God Himself.… The second station is the human station, exemplified by the following verses: “I am but a man like you.” “Say, praise be to my Lord! Am I more than a man, an apostle?” These Essences of Detachment, these resplendent Realities are the channels of God’s all-pervasive grace. Led by the light of unfailing guidance, and invested with supreme sovereignty, They are commissioned to use the inspiration of Their words, the effusions of Their infallible grace and the sanctifying breeze of Their Revelation for the cleansing of every longing heart and receptive spirit from the dross and dust of earthly cares and limitations. Then, and only then, will the Trust of God, latent in the reality of man, emerge, as resplendent as the rising Orb of Divine Revelation, from behind the veil of concealment, and implant the ensign of its revealed glory upon the summits of men’s hearts.”
(Bahá’u’lláh, Gleanings from the Writings of Bahá’u’lláh, p. 66)
“These mirrors are the Messengers of God Who tell the story of Divinity, just as the material mirror reflects the light and disc of the outer sun in the skies. In this way the image and effulgence of the Sun of Reality appear in the mirrors of the Manifestations of God. This is what Jesus Christ meant when He declared, “the father is in the son,” the purpose being that the reality of that eternal Sun had become reflected in its glory in Christ Himself. It does not signify that the Sun of Reality had descended from its place in heaven or that its essential being had effected an entrance into the mirror, for there is neither entrance nor exit for the reality of Divinity; there is no ingress or egress; it is sanctified above all things and ever occupies its own holy station. Changes and transformations are not applicable to that eternal reality. Transformation from condition to condition is the attribute of contingent realities.”
(‘Abdu’l-Bahá, The Promulgation of Universal Peace, p. 173)
Note: Bahá’í Writings use the pronouns He, His, and Him when referring to God, with the understanding that God is not a physical being.
