The supreme authority for Christian theology is the Triune God and the Holy Scriptures through which he speaks. The Lutheran Scholastic theologians, beginning with Johann Gerhard, spoke of theology’s “principle of being” (principium essendi) and principle of knowledge (principium cognoscendi). Theologians in the Protestant tradition often speak of Holy Scripture as the supreme authority in Christian theology. This is not incorrect. But it should be qualified by recognizing along with the Lutheran Scholastics that although Holy Scripture is the inspired Word of God, its authority ultimately rests on the authority of the Triune God who through it addresses humanity.
Affirming that Holy Scripture is the foundation and source of all true Christian theology does not rule out the reality that God speaks through other mediums. Indeed, Luther speaks of all creatures as God’s masks, channels, and created words through which God addresses humanity. The eighteenth-century Lutheran philosopher Johann Georg Hamann spoke of humanity as enveloped by God’s address through creation.
Nevertheless, we must make a distinction between God’s auditory and visible words. God acts on his creatures through the physical mediums of the whole of creation. However, God only tells humans how they are to know him in these physical mediums through his auditory Word. God’s auditory words were revealed to the prophets and the apostles and written down in the Bible. We know that the Scriptures are the inerrant Word of God because Jesus Christ affirmed their authority and proved his own by rising from the dead.
