What is Evangelical Theology?

I recently started reading "Introduction to Evangelical Theology" by Karl Barth and in his introductory comments, he lays out a basic definition of what he means by "evangelical theology" which is invigorating and has stayed in my my mind for a few days now. I wanted to briefly summarize what he stated and then share a few quotes with you from this first chapter. As I read his chapter, and almost every time when I read Barth, I wanted to highlight every single word; but that would not be very conducive for future reflection so I have just selected a few of my favorites points of his. First the summary and then the quotes:

Summary:
Barths' basic definition is that evangelical theology is the study of the God of the gospel. In poetic and scholastic writing he brings out the two main elements of this definition: GOOD AND GOD; the euangelion and theo. Barth first strongly lays out that theology is "theo-centered", its subject is God- a personal and ultimate being. It is a study of God. And then he goes on to show how evangelical theology is studying God as revealed in the bible which finds its centerpiece the gospel. It is studying the revelation that the ultimate being is a good and loving one! The God of the bible is a God bringing and announcing good news.

Quotes:
"The theology to be introduced here is evangelical theology. The qualifying attribute 'evangelical' recalls both the New Testament and at the same time the Reformation of the sixteenth century. Therefore, it may be taken as a dual affirmation: the theology to be considered here is the one which, nourished by the hidden sources of the documents of Israel's history, first achieved unambiguous expression the writings of the New Testament evangelists, apostles and prophets; it is also, moreover, the theology newly discovered and accepted by the Reformation of the sixteenth century. The expression 'evangelical', however cannot and should not be intended and understood in a confessional, that is, in a denominational and exclusive, sense. This is forbidden first of all by the elementary fact that 'evangelical' refers primarily and decisively to the Bible, which is in some way respected by all confessions. Not all so called Protestant theology is evangelical theology; moreover there is also evangelical theology in the roman Catholic and Eastern orthodox worlds, as well as in the many later variations, including deteriorations, of the Reformation departure. What the word 'evangelical' will objectively designate is that theology which treats of the God of the Gospel."

"The object of evangelical theology is God in the history of his deeds...Let it be noted that evangelical theology should neither repeat, re-enact, nor anticipate the history in-which God is what he is. Theology cannot make out of this history a work of its own to be set in motion by itself. Theology must, of course, give an account of this history by presenting and discussing human perceptions, concepts and formulations of human languange. But it does this appropriately only when it follows the living God in those unfolding historical events in which he is God. Therefore, in its perception, meditation, and discussion, theology must have the character of a living procession. Evangelical theology would forfeit its object, it would belie and negate itself, if it wished to view, to understand, and to describe any one moment of the divine procession in 'splendid isolation' from others. Instead theology must describe the dynamic interrelationships which make this procession comparable to a bird in flight, in contrast to a caged bird...the god of the Gospel rejects any connection with a theology that has become paralyzed and static. Evangelical theology can only exist and remain in vigorous motion when its eyes are fixed on the God of the Gospel." 

"Evangelical theology is concerned with Immanuel, God with us! Having this God for its object, it can be nothing else but the most thankful and happy science"
