Hello everyone and welcome back to Deeper Waters where we are diving into the ocean of truth. I’ve been looking at the topic of presuppositionalism lately and tonight, I’d like to look more at the topic of natural theology in this area and see if we can truly study God without special revelation.
Theology is the study of God. God can be studied either through special revelation or general revelation. Suppose you have a new neighbor move in. How can you know this person? You could know them by studying humanity in general and that would give you some information about the person, or you could get to know them simply by ringing the doorbell and letting them tell you about themselves.
Can we know God by only the first way? To an extent. You will get some true beliefs if you do natural theology right, but your certainty of them can be lacking and it will not be as efficient as God revealing Himself. However, let us not be too quick to throw out natural theology as useless.
The way we study God in natural theology involves what is called metaphysics. Now metaphysics is one of those terms that’s often tossed around in philosophical circles, but it is not really defined. However, if you use it, you can get the impression of being an intellectual and sound really cool while just using the term as a catch-all.
Let’s go ahead and explain metaphysics then. Metaphysics is the study of being as being. Physics is the study of material being in motion. Angelology is the study of angelic being. Zoology is the study of animal being. Botany is the study of plant being. You get the idea of where this is going.
Metaphysics has that contrast because while the other sciences study a particular type of being, this science studies being as it is. There is no doubt that a physicist could very well, and likely does know very well, more about matter in motion than the metaphysician, but the physicist likely will not know as much about that matter in motion as being. (Particularly if he’s a new atheist.)
Note that metaphysics is NOT the study of God. However, God is included in the subject of metaphysics. How? Let’s go back to your neighbor again. Studying anthropology will involve having your neighbor be a subject of that study, but your neighbor is not the particular object of that study. Anthropology does not exist to tell you about your neighbor in particular but your neighbor as a human being. Metaphysics tells you about God based on His relationship to being.
For Aquinas, God’s very essence IS being. Whatever it means to be is to be found in God and so studying being as being will give information about God. All being is true, good, and beautiful, for instance. From these, Aquinas did develop numerous doctrines of God, though of course not original with him. The main one after existence was simplicity. God’s existence IS his essence.
Note that in looking at natural theology, Aquinas does not cover concepts like the Trinity, although he believes in them. These cannot be known through natural theology. Consider for a parallel studying history. By history, you could know that Jesus was crucified on a cross even without the New Testament. You need revelation however to know that Jesus died for the sins of the world. A simple study of history apart from the revelation of God being read directly or communicated through others would not reveal that.
So can God be studied without Scripture? Yes. Will it be as good? No. Still, it is important and we must remember our reason is not antithetical or opposed to Scripture, but a tool God gave to help us understand Him and His revelation better.
