Introduction
Throughout the course of history varying opinions of the compatibility of faith and reason have been formed. In recent years, the relationship between faith and reason has lacked the attention which was given throughout most of Christian history. Much of that is due to the emphasis on (mystical) experience in the present Christian culture; this seems to be partially a result of the influence of the subjectivism and relativism latent in the postmodern worldview. Philosophical and reasoned theological discourse appear to be marginalized to the academic realm and thus popular Christian culture suffers from intellectual anemia and an anti-intellectual mentality. Thus, faith and reason are often set at odds within the current Christian climate and the wider contemporary culture has a low intellectual view of faith – particularly the Christian faith.
Most would not regard faith synonymous with reason but consider matters that are accepted in faith (belief in the absence of or in opposition to evidence) antithetical to reason (following evidence). [1] While it is true that many matters accepted by faith are generally beyond the realm of human reason and natural phenomena (evidence), is it accurate to say that what is trusted in faith is unreasonable or irrational and does not correspond with reality? Additionally, faith is often considered to be merely a “blind leap” of speculative hope founded on questionable ideas, naïve sentimentalities, or spurious personalities. Admittedly, there are many kinds of faith exercised that are naïve, irrational, and purely speculative; and there are many who place faith in erroneous ideas and questionable personalities. However, there is a kind of faith presented in the Christian Scriptures – the Holy Bible – that is sound, reasonable, and certain.
The Incompatibility and Compatibility of Faith and Reason
Founded on supernatural revelation that goes beyond human reason – faith is grounded in historical realities and not only stands compatible with reason, but establishes the right use of it. Scripture teaches an incompatibilist and compatibilist model of understanding the relationship of faith and reason. In the incompatibilist model, human reason stands opposed to faith as it is founded on the presupposition of humanism (man is the center of all things) and naturalism (the world can only be understood by what is seen and interpreted by human reason alone) without regard to a presupposition of a supernatural metaphysic (that there is a God that has created and sustains all things) established and explained by revelation (God’s transcendent revealing of himself in real time and space history). In the compatibilist model, faith and reason are seen as faculties of the mind and are mutually exercised on the basis of revelation. The right use of reason is established by faith in the truth of what has been revealed. Reason apart from God’s revelation thus becomes defective irrational and unable to come to a knowledge of what is ultimately true. The kind of faith that establishes the right use of reason is distinct from other religions because it is founded upon the revelation of God elucidated in the Christian Scriptures with the apex of this revelation being in the person of Jesus Christ. This definition of faith found in the Christian Scriptures is best described in the New Testament letter to the Hebrews.
What is Faith? – A Definition from Hebrews 11
The Scriptures present faith as inseparable from reason; faith is a confidence and firm conviction based upon hearing the truth. Thus, the foundation of biblical faith is truth. It is never on the basis a hunch, a vague hope, or what is often called a “blind, leap of faith” (or necessarily without the preponderance of evidence or in opposition to). Furthermore, the Scriptures teach that faith produces understanding; faith is an exercise of the mind that results in a depth of knowledge and insight. Thus, reason and faith are not antithetical but interrelated and necessary for the basis of spiritual knowledge as well as all knowledge. This understanding of biblical faith is most clearly seen in the New Testament letter to the Hebrews, particularly in chapter 11.
The book of Hebrews is primarily an exhortation (13:22) to Jewish believers endure and “hold fast the confession” (3:1, 4:14, 10:23) of in faith in the true Messiah – Jesus Christ and the promise of eternal rest (4:1-11) and not fall away in light of ensuing persecution (10:32-35). In order to encourage faithful perseverance, throughout the letter, the author contrasts true faith with unbelief and then ultimately defines faith in chapter 11:1. The writer goes on to describe faith (a trust, confidence) as the “substance” (a firm/solid assurance) “of things hoped for” and “the evidence” (conviction, absolute certainty) “of things not seen.” From the immediate context, we can discern that the “things not seen” is the promise just stated in 10:36; this promise is the promise of Christ’s coming with His reward (cf. 10:36, 37, and 39). The firm assurance and absolute certainty of faith is in is the promise of the Word of God (“what is promised”). The truth of what is promised is the substance of faith. Not only is the truth the substance of faith – but faith (as an assurance and absolute certainty) is the evidence of the promise itself – i.e. – faith is a testimony to the truth. Faith recognizes the truth and acts as an eye witness to it.
It becomes apparent that biblical faith/belief is not a blind leap into something without evidence or is unreasonable, but it is a fixed conviction upon truth. In this way, it begins to be seen that faith is not incompatible with reason – but compatible. The compatibility of faith and reason continues to be seen in verse 3 when the writer says: “By faith we understand that the worlds were prepared by the word of God, so that what is seen was not made out of things which are visible.” The word “understand” here is noieo, lit., to exercise the mind (observe). It is to comprehend, to perceive, and think. It is distinguished from observing/perceiving through physical sight but through a perception of the mind; it is an exercise of the mind accepting what is true. This comprehension is that the world was made “by the word of God.” Marvin R. Vincent’s New Testament Word Study on Hebrews says: “Here is meant the inward perception and apprehension of the visible creation as the work of God, which follows the sight of the phenomena of nature.” Faith’s compatibility with reason is that faith comprehends (the evidence of) the visible world as being made by God. The truth of the evidence of creation “declares the glory of God” (Ps. 19:1) and faith “understands” this. As Clement of Alexandria exclaimed, “Credo ut intelligam” – i.e. – “I believe in order that I may know.”[2]
However, while a compatibility of faith and reason can be seen in this explanation of faith, an incompatibility can also be seen. In both verses one and three, the object of faith has been the revealed truth of the word of God; this revelation goes beyond the realm of human reason and empirical rationality. In verse one, the object of faith is the promises of God (particularly the promise of Christ’s eventual return) that is the assurance and conviction of faith. In verse three, the object of faith is the unknown (God) behind the known (creation) being understood through the known (creation); but, there is only one way the unknown can be known – if it is made known, and that is through the revealed truth of God. Consequently, while our minds exercise faith in the revealed truth, in actuality the faith that results in a knowledge of the truth – is itself a product of the Divine word and not of our own will power. In this sense faith is incompatible with human reason, but compatible with Divine reason that is brought forth in the human mind by the revealed Word of God (James 1:18). This accords with the words of Aquinas, “it was necessary f
or the salvation of man that certain truths which exceed human reason should be made known to him by divine reason.”[3]
So, it is no wonder that some can look at nature and all its grandeur and not believe in the reality of a almighty Sovereign God – it is because they do not and cannot comprehend, i.e., they don’t have eyes of faith to bear witness to the truth! Thus, faith in and through the divine revelation is the epistemological necessity of truth. Meaning, that without faith we can never come to an accurate knowledge of the truth and a right understanding of reality; however, by faith Divine reason (the Word of God) is imparted to the human mind to be assured and convinced of the truth in order think properly about reality and act according to that Divine reason. Thus, faith and reason are not opposed to one another – but faith establishes the right and divinely intended us of reason and that is to “think God’s thoughts after Him.”[4]
Conclusion
Faith itself is the assurance and certainty – this picture presents faith as a faculty or even a foundation. It would be better understood as a faculty because it is by faith that the author of Hebrews describes the accomplishment of all the resulting actions of the “heroes of faith” in Hebrews 11. So, faith is seen as volitional. In faith as a faculty of the mind – it must be understood that it is not something that one has or doesn’t have per se – it is something someone is always exercising. Granted, it must be said here that there are varying kinds of faith. Additionally, what makes faith differing is because faith is often exercised toward a different object.
We were created to know God – to know Him rationally (right reasoning) and relationally. These aspects of relationship with God were both lost in man’s fall into sin. Biblical faith (as described in Hebrews) is merely the restoration of man’s ability to rationally know God and His truth. Through faith, Christian believers have a rational certainty of God that causes them now to think and live as man was intended. So, true biblical faith will result in actions that are consistent with God’s revelation of His ways and intentions for mankind. This is what it means that faith without works is dead – because faith produces the actions that God intended. Thus, faith and divine reason work in tandem to produce right reasoning resulting in the glory of God through the testimony of the eye witness of faith.
