Bahaullah never said that he was a "First Bahai". Did he, please?
If yes, please quote from him from Iqan, his concepts book.
I understand that perhaps followers of Bahaullah are ahead or stronger followers of Bahaism than Bahaullah was himself. Bahaullah never claimed that he was "First Bahai", yet his followers here say he was a "First Bahai", it suggests that now Bahaullah is to follow the Bahaism people and likewise, perhaps, the UHJ also instead of they following Bahaullah.
Its all a distraction with names paarsurry, the purpose of all the Messengers is the Worship of our One God, Allah. Submission to Allah, paarsurry
That requires us to become Loving to all humanity and serve all with humility, virtue and justice.
Consider, Baha'u'llah has shown a dinky die aussie in a material focused world, what the purpose was that Allah gave to Muhammad through the Quran. What other proof is needed? Names can become a barrier, only when we use them as veils.
