We shall inquire, however, whether the thing which Greek philosophers call ἀσώματον, or “incorporeal,” is found in holy Scripture under another name. For it is also to be a subject of investigation how God himself is to be understood—whether as corporeal, and formed according to some shape, or of a different nature from bodies—a point which is not clearly indicated in our teaching. And the same inquiries have to be made regarding Christ and the Holy Spirit, as well as respecting every soul, and everything possessed of a rational nature. (From the preface)

How do we understand God? Can we understand God?

How do we understand ultimate reality? Can we understand ultimate reality?

This is beyond what we know, but is worth our inquiry.

Even if this inquiry is beyond what we can know, it is worthy of our effort.

In many ways this inquiry is our life.
