Spinozistic Pantheism, the Environment and Christianity

I am not a pantheist and I don't believe that pantheism is consistent with Christianity. My preferred speculation is what I call the Swiss Cheese theory: we and our artefacts are the holes in God, the only Godless parts of reality. In this paper, I begin by considering a world rather like ours but without any beings capable of sin. Ignoring extraterrestrials and angels we could consider the world, say, 5 million years ago. Pantheism was, I say, true at that time. That is my qualified endorsement of pantheism. I then use the Sin premise, namely that we are capable of sinning, to argue that beings like us are not parts of God and I examine some consequences.
