What Bahá'u'lláh said in relation to the status of Baha and Ali - the greater branch, etc - has been posted enough times.
That you try to make out that this is purely spiritual status is absurd.
It is absurd because the conflict that occurred between Ali and Baha proves status and station within the organization and not some nebulous notion of 'spiritual status.'
You have nothing. There was in fact a recorded leadership dispute between Ali and Baha, so your denial has no credibility.
