In theology, the term "nature" has several distinct usages. Bauckham explains that he wishes to focus on the modern usage of the term, namely, as it refers to "the observable non-human world." He critiques such usage, explaining that it tends toward a focus on the natural environment of human life on "our" planet. Bauckham's concern is that a misleading distinction between "nature" and humanity can easily be supposed. He argues that what is distinctively human emerges from a deep continuity with the rest of nature and is not so easily defined as is often supposed. His theology of nature begins with a concern about the relationship between humanity and "nature."
