Christ is not a person, nor will Christ return as a particular person.
Jesus was a person who evolved to a ascension and achieved the Christ consciousness.
The return of Christ is happening in our current times, known as the Christ consciousness that is part of the 4th dimension, a stepping stone to a ascension into the 5th or higher dimensions.
The return of Christ is a return of the Christ consciousness where like never before anywhere in the universes, the souls of Earth can ascend keeping there current bodies, this is the return of the Christ consciousness.
If you are saying that Baha'u'llah had the Christ consciousness, that is different to being the return of Christ.
The issue here is that the return of Christ is set for a particular time period of the souls of Earths evolution, not almost 200 years ago.
So telling followers that Baha'u'llah is the return of Christ is a brainwashing method, when it is far from the truth.
Baha'u'llah was like many today in the spirituality communities, known as one of the first wave of 144,000 ascended masters lightworkers that has currently increased into the millions of awakened souls with the same knowledge and abilities as Baha'u'llah.
Baha'u'llah is no different than the millions of souls like myself during current times, the only difference being that he managed to brainwash others by means of control and saying he is the return of Christ, when he was no more special or knowledgeable than any other soul who could access such knowledge by going within, or the current lightworkers of our current times.
