First Sunday of Advent, December 2, 2018
God’s revelation in its objective reality is the incarnation of His Word, in that He, the one true eternal God, is at the same time true Man like us.
God’s revelation in its objective reality is the person of Jesus Christ.
In establishing this we have not explained revelation, or made it obvious, or brought it in the series of the other objects of our knowledge.
On the contrary, in establishing this and looking back at it we have described and designated it a mystery, and not only a mystery but the prime mystery.
In other words, it becomes the object of our knowledge; it finds a way of becoming the content of our experience and our thought; it gives itself to be apprehended by our contemplation and our categories.
But it does that beyond the range of what we regard as possible for our contemplation and perception, beyond the confines of our experience and our thought.
It comes to us as a Novum (a new thing) which, when it becomes an object for us, we cannot incorporate in the series of our other objects, cannot compare with them, cannot deduce from their context, cannot regard as analogous with them.
It comes to us as a datum (a piece of information) with no point of connection with any other previous datum.
It becomes the object of our knowledge by its own power and not by ours.
from Karl Barth, “The Miracle of Christmas”, Church Dogmatics I.2, page 172
