Barth's book on Boundaries

What is the relevance of science to the doctrine of creation?

What is the relevance of the doctrine of creation to science?

Can we define a boundary between science and theology?

In his Preface to The Doctrine of Creation (Church Dogmatics 3.1), Karl Barth states

The theological principle which I accept without a rival has made it almost compulsory that I should first present the doctrine of the work of the Creator as such in the old-fashioned form of a radical exposition of the contents of the first two chapters of the Bible.

..... It will perhaps be asked in criticism why I have not tackled the obvious scientific question posed in this context. It was my original belief that this would be necessary, but I later saw that there can be no scientific problems, objections or aids in relation to what Holy Scripture and the Christian Church understand by the divine work of creation.

..... There is free scope for natural science beyond what theology describes as the work of the Creator. And theology can and must move freely where science which really is science, and not secretly a pagan Gnosis or religion, has its appointed limit. I am of the opinion, however, that future workers in the field of the Christian doctrine of creation will find many problems worth pondering in defining the point and manner of this twofold boundary.
