I do not believe that the Son of man coming in the clouds verses mean what Christians believe they mean.
Christians interpret those verses literally but Baha'is believe that "clouds" is a metaphor for clouded judgment.
To explain in brief, I believe that ‘Son of man coming in the clouds of heaven’ means that the return of the Christ Spirit promised in the Bible will be made manifest from
the heaven of the will of God, and will appear in the form of a human being. The term “heaven” means loftiness and exaltation. Although Jesus was delivered from the womb of His mother, in reality He descended from the heaven of the will of God. Though dwelling on this earth, His true habitation was the realms above. While walking among mortals on earth, Jesus soared in the heaven of the divine presence.
Baha’u’llah explained the meaning of clouds in
The Kitáb-i-Íqán. The term “clouds” as used in the Bible means those things that cloud our judgment and prevent us from seeing what is really there. Just like the physical clouds prevent the eyes of men from beholding the sun, the desires of men hindered men from recognizing the return of Christ.
To further explain the teaming of clouds, Baha’is believe that the term “clouds” as used in the Bible means those things that are contrary to the ways and desires of men. They signify, in one sense, the annulment of laws, the abrogation of former Dispensations, the repeal of rituals and customs current among men. In another sense, they mean the appearance of a Manifestation of God in the image of mortal man, with such human limitations as eating and drinking, poverty and riches, sleeping and waking, and such other things as cast doubt in the minds of men, and cause them to turn away. These “veils” to recognition of a Manifestation of God are symbolically referred to as “clouds.” Just like the physical clouds prevent the eyes of men from beholding the sun, these things hinder the souls of men from recognizing the light of the Manifestation of God.
Thus the meaning of clouds is symbolic, not literal. Their judgment was clouded. Christians were looking for
the same man Jesus in the same body that resurrected and ascended to appear in the actual physical clouds in the sky with power and great glory, trumpets and angels, but when that did not happen that way they rejected Baha’u’llah. However, if one looks at what happened before, during and after Baha’u’llah appeared there is not one prophecy that cannot be applied to Him.
Thus when Jesus said
“ye shall see the Son of man sitting on the right hand of power, and coming in the clouds of heaven” we believe that means that His Return, the next Manifestation of God, would reside in the loftiness and exaltation of the divine presence (heaven), and would come down to earth by the will of God in the clouds (veiled from the sight of most people), like a thief in the night.
The reason Christians missed recognizing Baha’u’llah in the mid-19th century (and still do not recognize Him) is because they are waiting for the “literal fulfillment” of those Son of man in the clouds of heaven prophecies. They expect the same physical body of Jesus to come floating down on a physical cloud from heaven, but I am sure you already know this since it is a basic Christian belief.
