Reformed Epistemology versus Classical Apologetics

Introduction

Reformed epistemology and classical apologetics are two philosophical approaches to demonstrating the rationality of belief in God. Reformed epistemology asserts that belief in God is properly basic—rationally justified apart from external evidence—while classical apologetics seeks to offer and argue for evidence for God from nature or history, providing a logical defense. Rather than being contradictory, these approaches are complementary. This short essay will examine the strengths and weaknesses of the two systems and propose a synthesis that integrates their insights into a robust system for defending the Christian faith, whether it be in an academic setting or anywhere else.

Reformed Epistemology

Reformed epistemology is greatly influenced by the theology of John Calvin, who posits the following:

There is within the human mind, and indeed by natural instinct, an awareness of divinity. This we take to be beyond controversy. To prevent anyone from taking refuge in the pretense of ignorance, God himself has implanted in all men a certain understanding of his divine majesty… Therefore, since from the beginning of the world there has been no region, no city, in short, no household, that could do without religion, there lies in this a tacit confession of a sense of deity inscribed in the hearts of all.¹

Calvin’s words greatly reflect the reality of Romans 1. God’s existence is perceived clearly by all of creation, yet believing God has been traded for believing in debased and grotesque things. Still, as Calvin points out, religion, although sometimes misplaced, is so necessary and foundational, that it has remained a core aspect of the human experience since the beginning of time. Therefore, God’s existence cannot be refuted and no external evidence is necessary. God is indeed central to the human experience, for all know Him. Reformed Epistemology is particularly strong because it agrees with this foundation truth of Scripture.

How is it that all people allegedly know God but there are many who deny Him? This question can be interpreted as a weakness of the position, yet advocates of reformed epistemology have an answer: “For although they knew God, they did not honor him as God or give thanks to him, but they became futile in their thinking, and their foolish hearts were darkened” (Rom. 1:21).² Sin is the reason some reject God, although deep down all know Him. Is there anything that can be done?

Classical Apologetics

As mentioned previously, classical apologetics is concerned with logical arguments for God’s existence, as opposed to the sole rationality of belief in Him. It is strong because it seeks to demonstrate this rationality, although this is not a requirement per the reformed epistemologists, and this evidence-driven approach is very familiar in today’s world, driven by empirical study and experience. However, it could be interpreted as too modest by many, for it is not as concerned with agreeing with Scripture as it is with providing logical arguments. With that said, alongside reformed epistemology it has a valid position in Christian apologetics.

Conclusion: How the Two Approaches Fit Together

The best form of Christian apologetics incorporates both classical apologetics and reformed epistemology. For Christians, the Gospel is of first importance (1 Cor. 15:3), so arguing that God is properly basic and needs no proof is as essential as explaining that all people are sinners and misunderstand and refute God’s existence because of this state. At the same time, sin has darkened the hearts of all people and external evidence can be useful for allowing the Gospel to shine in. Therefore, apologetics is best done when it acknowledges the Scriptural truths of sin and depravity, rebellion against God, and the Gospel. Since the climax of the Gospel message occurred at a given point in history, it is not improper to use natural and temporal events and histories as evidence for the Christian God. Indeed, God is sovereign over all things and has provided evidence for Himself, although it is not required.
