Bahai - an evil deception ?, page-136

If you reject Baha'u'llah you reject Christ. Baha'u'llah is quite clear about this.

"Be thou assured in thyself that verily, he who turns away from this Beauty hath also turned away from the Messengers of the past and showeth pride towards God from all eternity to all eternity" - Baha'u'llah

So the answer to your question is yes, but is a broader view of who Jesus was.

So between me and you, I am the only true believer in Jesus. You have rejected Him
