At a theoretical level, I think a naturalist approach to religion is just asking questions I'm not interested in. They're perfectly legitimate in their own terms, but they don't address the actual experience of how one or other aspect of religion becomes existentially meaningful to us in our actual lives. The fact that we ourselves are the subject of investigation makes all the difference.

It seems that just Being, the sheer fact of existence, that there is something rather than nothing, already inspires a wonder akin to religion. But - as in my comment about the Kingdom of God in the last answer - Jewish and Christian traditions are also prepared to challenge what 'is' for the sake of what could be.

There are kinds of unity other than those of the explicit and systematic unity that Poole is attacking. There are kinds of movement - in music or athletics, for example - that present themselves as having a certain unity about them. In some sphere we might talk about 'style'.

For others the mourning is over. Others would say that whilst one God has died - the God of ontotheology perhaps? - this allows for the good news of a God who is to come, a God who will be better able to gather up and give justice to all the manifold aspirations of human life towards goodness and meaning (and not just to those who are able to fit into a narrow 'religious' framework).

Now, as at the beginning of the 19th century, there is a certain discovery of Eckhart and related figures. There are questions as to how far our Eckhart accords with the real medieval teacher of that name, but there are certainly images in his work that help us work our way past several of the aporia with which we're confronted in our attempts to think about God.

In a sense these are questions that most people ask themselves to some extent. They become philosophical when asked with a persistence and rigour that pushes past conventional or evasive answers. It's nothing to do with acquiring a technical facility in an academic discipline.

One of the most violent attacks on the Church in the Soviet Union was under Kruschev when, during a period of economic and political liberalization, he attacked the Church to demonstrate to old Party members that he hadn't lost it.
