The Urantia Papers have a most glorious presentation of what it calls the 'Paradise Trinity', see
here. My concept of 'God' includes a tri-une concept, but is not limited to it, since the Infinite Itself is beyond finite definition and knowledge, it just IS. - therefore there are aspects of Deity that are pre-personal, personal, super-personal, trans-personal, etc. - the UB wonderfully expounds upon these various dimensions. The Bible has in some places by virtue of insight and limited revelation, a triune-concept of Deity, but the UB further unveils it in the greater cosmic perspective.

The Infinite is beyond the scope of the finite, so it might be best to recognize that 'God' comes in many forms and personalities. Its not "anything and everything goes", its the knowledge that there is a universal omnipresent spirit-presence and awareness at the heart of all that exists, as the source and context from which all creation arises (all things/beings).
There is only this
infinite intelligence apart from which nothing can exist, which is the source of all. The Infinite itself is
unknowable. It can only be assumed as the source of the finite, the origin and sustainer of existence.
Still forever,...
'God' is One. This Oneness includes all, pervades all, encompasses all, transcends all, since nothing can exist outside of 'God'.
