Right.
I read his website. He doesn't seem to claim he has a new Book with new Laws.
And it appears only in this example he claimed that God is speaking.
Baha'u'llah wrote:
"Whoso layeth claim to a Revelation direct from God, ere the expiration of a full thousand years, such a man is assuredly a lying impostor. We pray God that He may graciously assist him to retract and repudiate such claim. Should he repent, God will, no doubt, forgive him. If, however, he persisteth in his error, God will, assuredly, send down one who will deal mercilessly with him. Terrible, indeed, is God in punishing! Whosoever interpreteth this verse otherwise than its obvious meaning is deprived of the Spirit of God and of His mercy which encompasseth all created things."
It is not like he is adding or removing any Shariah Laws from Last Book of God (Aghdas), and saying follow these new laws. So, in this sense he is not misleading people. He seems to teach unity of mankind. Many of his words are like Bahai Books.
And if it was only one time claim that God spoke to him, then God could forgive him.
At least for Bahais there are Criterias.
For example Baha'u'llah wrote before every
Manifestation, A star must appear in the sky:
"In like manner, in the invisible heaven a star shall be made manifest who, unto the peoples of the earth, shall act as a harbinger of the break of that true and exalted Morn. These twofold signs, in the visible and the invisible heaven, have announced the Revelation of each of the Prophets of God, as is commonly believed."
