Christ as the primary theme

I sense that paragraph 8 is where things start to heat up. Volume 1 is all about revelation. Barth makes this comment: "God reveals Himself as the Lord; in this statement we have summed up our understanding of the form and content of the biblical revelation." CD I.1,p314

And, further on the same page:

"Historically considered and stated the three questions answered in the Bible, that of revealer, revelation, and being revealed, do not have the same importance. The true theme of the biblical witness is the second of the concepts, God's action in His revelation, revelation in answer to the question what God does, and therefore the predicate in our statement. Within this theme the two other questions, materially no less important, are answered. Similarly the doctrine of the Trinity, when considered historically in its origin and development, is not equally interested in the Father, the Son and the Holy Ghost. Here too the theme is primarily the second person of the Trinity, God the Son, the deity of Christ."
