I have been meditating lately on Barth’s view of The Word of God and I made this diagram to help me visualize it.
“There is no distinction of degree or value between these three forms. For to the extent that proclamation really rests on recollection of the revelation attested in the Bible and is thus obedient repitition of the biblical witness, it is no less the Word of God than the Bible. And to the extent that the Bible really attests revelation it is no less the Word of God than revelation itself. As the Bible and proclamation become God’s Word in virtue of the actuality of revelation, they are God’s Word: the one Word of God within which there can be neither a more nor a less. Nor should we ever try to understand the three forms of God’s Word in isolation. The first, revelation, is the form that underlies the other two (CD I/1, 120-121). Bruce McCormack notes that what Barth is after is a “unity-in-differentiation.” ^^ Each form is distinct from one another (as the persons of the Trinity are), yet are unified with each other (cf. CD I/2, 463).” Theopedia Karl Barth
