The subject-matter, origin and content of the message received and proclaimed by the Christian community is at its heart the free act of the faithfulness of God in which He takes the lost cause of man, who has denied Him as Creator and in so doing ruined himself as creature, and makes it His own in Jesus Christ, carrying it through to its goal and in that way maintaining and manifesting His own glory in the world.
— Karl Barth, Dogmatics [IV.I.p3)
