Five Ways Historic Christianity Relates Faith to Reason


Many people view faith and reason as being at odds with one another. For example, some differentiate faith from reason by asserting that faith merely involves hoping something is true, whereas reason involves affirming something to be true based upon justifying evidence. According to this model, faith is equivalent to wishful thinking and is thus incompatible with reason. But historic Christianity’s view of faith and reason is very different from this popular stereotypical definition.

In defining the relationship between faith and reason, historic Christianity draws upon both Scripture and sustained logical analysis. Here are five ways that historic Christianity relates faith to reason:

1. Faith’s Definition Involves Reason

In a biblical context, having faith (Greek: the verb, pisteúō, “believe”; the noun, pístis, “faith”) means confident trust in a credible source (God, Christ, or the truth). So the root word for faith in the New Testament is “trust,” but that confidence must be placed in a credible (reasonable and/or reliable) source. Thus, faith’s very definition includes a necessary rational element.

2. Faith Involves Knowledge

In Scripture, faith often involves knowledge. For example, saving faith by necessity includes knowledge, for having faith in Jesus Christ as Lord and Savior involves knowing certain historical facts about his life, death, and resurrection. So in historic Christianity, faith is connected to the rational knowing process.

3. Faith Is Compatible with Reason

The scholarly consensus of historic Christianity (reflected in such influential thinkers as AugustineAnselm, and Aquinas) is that faith should seek understanding. Thus, Christians should be interested in the rational foundations of their faith. And in conjunction, the Christian apologetics enterprise works to show that there are good reasons (facts, evidence, arguments) to believe in the truth claims of Christianity.

4. Faith Can’t Be Fully Comprehended by Reason, but Faith Does No Damage to Reason

Christian believers, as finite creatures, cannot fully fathom (exhaustively understand) the divine mysteries of the Trinity and the Incarnation, but those doctrines can be defined in ways that avoid being logical contradictions. For example, the Triune God’s oneness (essence) is in a different respect from his threeness (personhood), thus avoiding the violation of the law of noncontradiction (a thing, A, cannot equal both A and non-A).

5. God’s Rational Mind Grounds Human Reason

God’s rational mind, evident in the intelligent created order (Greek: nómos, “law”; lógos, “logic”), makes knowledge, reason, and truth possible. And humankind being created in the image of God guarantees that humans have the capacities to reason and discover truth.

So be ready to share these five points the next time a skeptic says faith and reason are incompatible.

    This is an excellent article and should be helpful in a conversation with a skeptic. However, how can this logic be applied to some of the Genesis account? For example, I know a skeptic who said he simply shut the Bible after reading about the long lives of Adam and those following in the generations up to Noah.

    Ken, what comes to my mind in response to your question for reflection is not specifically one of these five ways being the most helpful, but overall how God’s Spirit in us progressively encourages us to seek more and more understanding and knowledge of God as we go through life on our path to sanctification.
    For example, the Bible shows and instructs us that God uses trials and adversity for good and righteous purposes that are often hidden from His people on the surface. But through faithful prayer and deeper study and patient contemplation encouraged by the Spirit, we find the reasons for our adversities, the lessons God wanted us to learn, the situations He wanted to prepare us for, or the benefits that come out of the struggle, which brings us closer to God with an even stronger faith.
    Of course, this perpetual reinforcing growth in understanding doesn’t have to be accomplished only through adversity, this is just one way God designed faith and reason to fuel each other, not conflict and compete.

    The fourth example was most helpful to me. I have often found that many Christians think sin has rendered reason completely useless and, therefore, having no place in faith. It seems to me that the more biblical understanding of the effect of sin upon the human faculty of reason is that it is unable to cause salvation, but it does not necessarily mean it has no place in the life of the believer. Thanks for your intriguing thoughts!
