Systematic Theology: Volume 1, The Doctrine of God

The mystery of Almighty God is most properly an explication of the oneness of God, tying the faith of the church to the bedrock of Israel's confession of the LORD of the covenant, the LORD of our Lord Jesus Christ. The doctrine of divine attributes, then, is set out as a reflection on Holy Scripture: the One God as omnipresent, omnipotent, and omniscient, and all these as expressions of the Love who is God. Systematic theology must make bold claims about its knowledge and service of this One LORD: the Invisible God must be seen and known in the visible. In this way, God and God's relation to creation are distinguishedbut not separatedfrom Christology, the doctrine of perfections from redemption. The LORD God will be seen as compatible with creatures, and the divine perfections express formally distinct and unique relations to the world.

This systematic theology, then, begins from the treatise De Deo Uno and develops the dogma of the Trinity as an expression of divine unicity, on which will depend creation, Christology, and ecclesiology. In the end, the transcendent beauty who is God can be known only in worship and praise.
