Barth on Mary and Jesus

Given Barth’s well-known polemical style, this quotation is perhaps not that surprising:  

Mariology is an excrescence, i.e. a diseased construct of theological thought. Excrescences must be exised.

So there you have it! And then, just a few pages later, he comes up with a cracker:  

What in fact makes revelation revelation and miracle miracle is that the Word of God did actually become a real man and that therefore the life of this real man was the object and theatre of the acts of God, the light of revelation entering the world.
