Fools rush in where angels fear to tread. I have some tentative idea about what a usable Bahai doctrine would look like (bearing in mind that such a formulation would never be authoritative, since we have no doctrinal authority). I think your critique of Tonyfish’s formulation is correct: God the Father is not at a different level and distinct from the Word and the Spirit, in either the Christian or the Bahai revelation. So far as I can see it, in the largely unploughed field of Bahai metaphysics, Revelation and Creation and Spirit are all bound up in the Word (that is, the Word is a trinity), since the Word is said in the Bahai writings to be the origin of creation, it is naturally the origin of revelation, and the Spirit also is said to proceed from the Word. Beyond the Word is the unknowable essence of the Godhead, which is not to be reduced to any one of the three. That gives us a quaternity rather than a trinity. I don’t imagine for a moment that I could argue that this is a correct interpretation of the New Testament record, so I am not trying to “fix” the Christian trinity. Rather, this is the shape I could envision a Bahai understanding taking, as metaphysical questions are argued over the centuries. If I was looking for a Bahai scholar to discuss this with, it would be Nader Saiedi, who although he is best known for his work on the Bab’s writings, has an acute sense for the metaphysical distinctions which are implied by Baha’u’llah’s and Abdu’l-Baha’s choices of terms. Personally, I go glazy eyed with the talk turns metaphysical.
