So then, the knowledge of God is the only dogma, the exclusive content, of the entire field of dogmatics. All the doctrines treated in dogmatics—whether they concern the universe, humanity, Christ, and so forth—are but the explication of the one central dogma of the knowledge of God. All things are considered in light of God, subsumed under him, traced back to him as the starting point. Dogmatics is always called upon to ponder and describe God and God alone, whose glory is in creation and re-creation, in nature and grace, in the world and in the church. It is the knowledge of him alone that dogmatics must put on display.
By pursuing this aim, dogmatics does not become a dry and academic exercise, without practical usefulness for life. The more it reflects on God, the knowledge of whom is its only content, the more it will be moved to adoration and worship. Only if it never forgets to think and speak about matters rather than about mere words, only if it remains a theology of facts and does not degenerate into a theology of rhetoric, only then is dogmatics as the scientific description of the knowledge of God also superlatively fruitful for life. The knowledge of God-in-Christ, after all, is life itself (Ps. 89:16; Isa. 11:9; Jer. 31:34; John 17:3). For that reason Augustine desired to know nothing other and more than God and himself. ‘I desire to know God and the soul. Nothing more? No: nothing at all.’ —Herman Bavinck, Reformed Dogmatics
