It may sound a bit presumptuous to speak of the architecture of a dogmatics which is not yet complete, but the size and scope of Professor Barth's Church Dogmatics to date would seem to justify our attempt to examine its outer structure in order to discover the basic dynamic principles involved in this Protestant ‘Summa’. In following this procedure, however, we should be aware that we are working backwards, for, unlike the many dogmatics in which the Christian Faith has been forced into a pre-established mould, Professor Barth has been willing to cast the mould in accordance with the demands of the Faith itself. This is not to deny in any way the obvious human element involving meticulous planning and unusually sensitive organisational skill, but is to state clearly that the Church Dogmatics is not a system conforming to the dictates of human reason, but is a bold yet humble attempt to write a systematic theology which conforms to the revelation of God in Jesus Christ. As such, the architectural plans must necessarily result from obedient and faithful listening to the Word of God spoken to the Church, and all future designs must remain fluid and prepared for unexpected changes.
