you offered your suggestion not from Bahauallah but from his son.
In our view Abdul-Baha well represented his Father.
Bahá’u’lláh explicitly appointed ‘Abdu’l-Bahá as both the Interpreter of his teachings and the Centre of the nascent Baha’i community:
k174
"O people of the world! When the Mystic Dove will have winged its flight from its Sanctuary of Praise and sought its far-off goal, its hidden habitation, refer ye whatsoever ye understand not in the Book to Him Who hath branched from this mighty Stock."
I.B The faithful are bidden to refer whatsoever they do not understand in the Bahá'í writings to “Him Who hath branched from this mighty Stock”.
"Consider that which We have revealed in Our Most Holy Book: ‘When the ocean of My presence hath ebbed and the Book of My Revelation is ended, turn your faces toward Him Whom God hath purposed, Who hath branched from this Ancient Root.’ The object of this sacred verse is none other except the Most Mighty Branch [‘Abdu’l-Bahá]. Thus have We graciously revealed unto you Our potent Will, and I am verily the Gracious, the All-Powerful. 222 Verily God hath ordained the station of the Greater Branch [Muḥammad ‘Alí] to be beneath that of the Most Great Branch [‘Abdu’l-Bahá]. He is in truth the Ordainer, the All-Wise. We have chosen ‘the Greater’ after ‘the Most Great’, as decreed by Him Who is the All-Knowing, the All-Informed."

But it's true we don't have a credo that's recited regularly... We do have beliefs found in the Baha'i Writings.
