The previous post-debate between Brunner and Barth-raised the question of John Calvin’s teaching on the knowledge of God. It is a fundamental question that we all raise but also seems to be confused on occasion. Calvin teaches that there are three fundamental aspects when it comes to the knowledge of God: the Sensus Divinitatis (SD) (“sense of the divine in man” or internal knowledge), external Knowledge of God, and knowledge of God the Redeemer.
For Calvin SD amounts to a universal belief in God the Creator. In regards to SD Calvin gives us the following reasons: (1) Observation shows us that all men demonstrate belief in God. (2) The various expressions of religious worship throughout the world seem to indicate a genuine appeal to a conception of deity or ultimate authority (3) Even those who object to God have a conception of Him that they are objecting to. Such a conception of God renders all men without excuse before God their Creator. Therefore, this natural conception of God that is held by all is related to theological and moral knowledge (Institutes of the Christian Religion, Book 1, Chapter 3)
Calvin also taught that an external knowledge of God can be seen in the physical world. This is similar to what Paul says when writes “For what can be known about God is plain to them, because God has shown it to them. 20 For his invisible attributes, namely, his eternal power and divine nature, have been clearly perceived, ever since the creation of the world,in the things that have been made. So they are without excuse” (Rom. 1 ). Calvin does not offer a syllogistic argument for God’s existence in his discussion of the external knowledge of God. But he does teach that God’s attributes such as power and wisdom are revealed in creation (Institutes, Book 1, Chapter 5).
For Calvin, knowledge of God is distinguished from knowledge of God the Redeemer. The key distinguishing factor between these is the former is arrived at through natural revelation (external) while the latter through special revelation by the Holy Spirit (internal).
The key take away is the three part aspect to the knowledge of God SD, external, and knowledge of God the redeemer. Understanding how it is that we come to know God will help us understand how it is that we are to do as Christ explained in the Great Commission “make disciples”. Relying solely on external as some tend to do is insufficient. It is when we realize that the work of making disciples is completely God’s work then we can rely on God’s appointed means, the Gospel which is the power unto salvation, and the Holy Spirit the reveal-er of Gospel truth.
