Church Dogmatics (German: Kirchliche Dogmatik) is the four-volume theological summa and magnum opus of Swiss Protestant theologian Karl Barth and was published in thirteen books from 1932 to 1967. The fourth volume of the Church Dogmatics (CD) is unfinished, and only a fragment of the final part-volume was published, and the remaining lecture notes were published posthumously. The planned fifth volume was never written. Source: Wikipedia (en)
