Bahá’u’lláh was asked a series of philosophical questions by a learned Zoroastrian Mánikchí Sáhib concerning the nature of God and religion.
“Another question raised by the distinguished Sáhib is the following: “There are four schools of thought in the world. One school affirmeth that all the visible worlds, from atoms to suns, constitute God Himself and that naught can be seen but Him. Another school claimeth that God is that Essence that must of necessity exist, that His Messengers are the intermediaries between Him and His creatures, and that their mission is to lead humanity unto Him. Yet another school holdeth that the stars were created by the Necessary Being, whilst all other things are their effect and outcome. These things continually appear and disappear, even as the minute creatures that are generated in a pool of water. A further school maintaineth that the Necessary Being hath fashioned Nature through whose effect and agency all things, from atoms to suns, appear and disappear without beginning or end. What need then for an account or reckoning? As the grass groweth with the coming of the rain and vanisheth thereafter, so it is with all things. If the Prophets and the kings have instituted laws and ordinances, the proponents of this school argue, this hath merely been for the sake of preserving the civil order and regulating human society. The Prophets and the kings, however, have acted in different ways: the former have said ’God hath spoken thus’ that the people might submit and obey, whilst the latter have resorted to the sword and the cannon. Which of these four schools is approved in the sight of God?”
The answer to all this falleth under the purview of the first utterance that hath streamed forth from the tongue of the All-Merciful. By God! It embraceth and comprehendeth all that hath been mentioned. He saith: “Be anxiously concerned with the needs of the age ye live in, and centre your deliberations on its exigencies and requirements”. For in this day He Who is the Lord of Revelation hath appeared and He Who spoke on Sinai is calling aloud. Whatsoever He may ordain is the surest foundation for the mansions reared in the cities of human knowledge and wisdom. Whoso holdeth fast unto it will be reckoned in the eyes of the Almighty among them that are endued with insight.
These sublime words have streamed forth from the Pen of the Most High. He saith, exalted be His glory: “This is the day of vision, for the countenance of God is shining resplendent above the horizon of Manifestation. This is the day of hearing, for the call of God hath been raised. It behoveth everyone in this day to uphold and proclaim that which hath been revealed by Him Who is the Author of all scripture, the Dayspring of revelation, the Fount of knowledge and the Source of divine wisdom.” It is thus clear and evident that the reply to his question hath been revealed in the kingdom of utterance by Him Who is the Exponent of the knowledge of the All-Merciful. Happy are they that understand!
As to the four schools mentioned above, it is clear and evident that the second standeth closer to righteousness. For the Apostles and Messengers of God have ever been the channels of His abounding grace, and whatsoever man hath received from God hath been through the intermediary of those Embodiments of holiness and Essences of detachment, those Repositories of His knowledge and Exponents of His Cause. One can, however, provide a justification for the tenets of the other schools, for in a sense all things have ever been and shall ever remain the manifestations of the names and attributes of God”.
