Just as those who received the disciples received Christ in and through them, so we today in receiving their written words also receive Christ, and with him also the Father. In addition to Christ and Scripture, [Karl] Barth also thinks of the proclamation as a form of the Word of God. The church’s preaching today is the concrete means of God revealing himself and of men receiving the Word of God. In practice these three forms of the Word of God are inseparable. There is no revelation apart from Christ, but no knowledge of Christ apart from the Scriptures. In practice we know Christ and the Scriptures through the proclamation of the church, but we must test that proclamation by Scripture.
