The three forms of the word of God

I have heard there are three forms of the word of God and Glen recently mentioned it may originate with Barth/Luther. Barth certainly popularized the classification. There is a hierarchy, but they are all bound together. The three forms are:

1. the Personal/Eternal Word of God - Jesus Christ;
2. the Spoken word - the present proclamation in preached words and sacramental words;
3. the Written word - the Bible.

They are linked as:

• The Father speaks the Personal Word
• the Personal Word speaks the Spoken word (either directly or by his Spirit indwelt ambassadors)
• the Spoken word is recorded in the Written word
• the Written word serves the Spoken word by ensuring it continues to be heard
• the Spoken word serves the Personal Word by ensuring he continues to be heard
• the Personal Word serves the Father by ensuring he is heard

On the way from the Father each form of the word is Spirit-breathed by means of the previous, and on the way back to the Father serves the glorification of the latter by the Spirit.
