Wow, you do have a way of asking tough questions! Whaddaya say we round up Satan and Phil, go over to Lynchburg, and beard Falwell in his den? 
To answer you, I’m gonna have to bring in Upanishadi Hinduism (to the extent I understand it – not very well) and invent a “dogmatic paganism” that you, Matt, and the others would recoil from. But allow me a bit of systematics for the sake of argument, and also that I am not in any way trying to insult or belittle your faith if any wording I should happen to use might seem to do so. 'Kay?
The faiths descended from Abraham (Christianity, Islam, Judaism, and a few oddballs) are united in an insistence on one single God, creator of and “above” the world. He is in His Creation, He works through it, but Chaim, Zeeshan, FoG and I would all recall at any equating of Him with it. “He’s all that, and more…”
Now, any Hindu worth his salt is quite capable of accepting the seemingly-contrary-to-logic assertion that the multifold deities of his faith are, at rock bottom, one, the Brahman whose work the Atman is. And that Siva and the rest are manifestations of that one bottom-line god. Further, any of these deities can take on human form and live as a man; Vishnu made a career out of it, with something like 16 avatars to his credit.
The Greek scholars who converted to Christianity, however, did not have the benefit of the Upanishads and the scholarly treatises on Hindu metaphysics, and would have had a problem shifting their paradigms to comprehend it in any case – they had a big problem just dealing with the idea that “change” can be real!
So they constructed an elaborate metaphysic involving a single ousia with triple hypostases for God, and a split personality for Jesus, in order to fit the simple idea that “God manifested Himself in an unique way in the person of Jesus” into their systems. And any dogmatic theology restates, in one way or another, this intricate foofaraw to “explain” how this worked. (Anecdote: I once had occasion to counsel a quite intelligent woman who had no problem with one God, God shows himself through Jesus, Holy Spirit is God working in us, all one God, but was terrified that she was “not saved” because she could not grasp, much less accept, the dogma of the Trinity. Such are the webs we weave ourselves! :()
Now, if I understand animistic paganism accurately, and of course I am not schooled in it, there is a spark of the divine in everything (Christianity has no problem with this) and thus it is worthy of worship (red flag! Only God is worthy of worship! Yeah, but they’re not worshipping the tree, they’re worshipping God as revealed in the tree…). Analogously to Hinduism, these various “pieces of godhood” are mystically one, brought together in a god and goddess viewed as fructifying aspects of a single spirit found throughout Creation. And hey, I have no problem with this: “This is my Father’s world” to quote the old hymn. And if Christianity has historically been very patriarchal and given no credence to the feminine aspect in the divine, it has at least given lip service to the idea that God is neither male nor female. In a patriarchal society, He chose the image of loving Father and a male avatar – but He is by no means restricted here. And of course in Greek, Aramaic, and Hebrew, “Spirit” is feminine, and a statement of the order of “She comes into our hearts to lead us to Christ” would have been quite proper to our buddy St. Paul the Closeted.
So I see my belief structure as “complete,” without the Greek bookkeeping categories – though I quickly add that I am certain I have much to learn yet! And I see yours as “incomplete” because, though you have encountered the divine through His works, you do not (according to my interpretation) know Him in a loving interpersonal relationship through the living Jesus Christ, who is today as surely (IMHO) a living human being capable of interpersonal human relationships as are you and I. And that those who would invest Him with their smallmindedness have turned you off to His love is to my mind a great sin.
I believe in the Trinity – I love and trust one God who is, on my understanding, revealing Himself in three distinct persons (as well as through his world). I do not have any intellectual or emotional investment in the Dogma of the Trinity, if you can see the distinction.
And I am certain that much of what I have said here is inaccurate, because I have not walked in the garden of your mind, and have no way to know what it is you truly know, and feel, and love as regards your faith. But I have done the best I can to compare and contrast what I understand of yours with what I myself believe, and welcome the opportunity for correction and further dialogue on this.
