Is the Bible Sufficient?

 

The controversy over the “adequacy” of the Bible has generated plenty of heat in Evangelical circles.  But are “Bible only” advocates right in claiming that any combination of man’s philosophy and biblical wisdom is poison?

 

      Evangelicalism has been embroiled for some time in a controversy of no small proportion.  Authors we have trusted for years, whose counsel has elevated our Christian experience and deepened our understanding of ourselves and of God, have been branded “heretics.”

      Why have these men been vilified?  Because they promote principles gleaned from psychology and not specifically from the Bible, thus—according to detractors—producing a poisonous amalgam of godless philosophy and biblical wisdom. 

      The Bible is fully sufficient, say critics.  “The Word of God has been given to man as the sole source for finding God’s solutions to the real problems that plague him.” [emphasis mine]  They decry “futile attempts to mix God’s Word with unregenerate suppositions and theories.” [1]

      Now, it’s hard to argue with the noble desire to focus on training materials that are more directly biblical.  And it’s also possible that respected leaders in our midst can do us harm.  Wolves come in sheep’s clothing, after all. 

      Sometimes, though, the distinction between fleece and fur is not so easily determined.  Even proof texts that seem crystal clear at first, take on a different sense when examined more closely or when balanced against other scriptural teaching.

      I won’t comment here on the role of psychology in the life of the Christian except to say I’m a centrist on the issue.  I’m concerned with a more foundational idea:  Is the Bible “sufficient” in the sense that these critics claim?

 

Scripture on the “Adequacy” of Scripture

      “Bible only” advocates rely on a handful of references to prove that Scripture provides the sole solutions to life’s problems.  These three are characteristic:

 

•     “You shall not add to the word which I am commanding you, nor take away from it, that you may keep the commandments of the Lord your God which I command you” (Deuteronomy 4:2).[2]

•     “Do not add to His words lest He reprove you, and you be proved a liar” (Proverbs 30:6).

•     “And if anyone takes away from the words of the book of this prophecy, God shall take away his part from the tree of life and from the holy city, which are written in this book” (Revelation 22:19).

 

      None of these verses teach what is claimed.  The Deuteronomy passage only prohibits anyone from changing the specific revelation Moses has just given.  Note that 61 additional books of the Bible were written after Moses penned these lines in the Pentateuch.  The passage does not forbid the use of man’s observations about life and human behavior. 

      The Proverbs passage simply says not to add to God’s Word.  No Christian I’m aware of, though, considers principles of psychology equal to Scripture in authority. 

      Revelation 22:19 forbids adding to the “words of the book of this prophecy,” that is, the revelation itself.  This verse is not even limiting the extent of the canon, much less excluding human wisdom about man’s problems.

      Another passage however, 2 Timothy 3:16-17, is more substantial.

 

2 Timothy 3:16-17

      Paul writes in his last epistle, “All Scripture is inspired by God and profitable for teaching, for reproof, for correction, for training in righteousness; that the man of God may be adequate, equipped for every good work.”

      The reasoning of “Bible only” advocates goes something like this.  Paul says that Scripture is adequate.  If Scripture is adequate, then nothing more is required.  If nothing more is required, then the use of outside material implies the inadequacy of the Bible, contradicting Paul’s statement.  Therefore, nothing in addition to Scripture can be used to equip us, because nothing else is “profitable for teaching, for reproof, for correction, for training in righteousness.”  This function is the sole province of the Bible. 

      That’s the argument.  Here’s what’s wrong with it.  

      First, 2 Timothy 3:15 does not teach that the Scripture is adequate.  The word “adequate” modifies the believer, not the Scripture, “the man of God” who uses the inspired Scripture in a profitable way.  The words Paul uses to describe Scripture are “inspired” and “profitable,” not “adequate.”  The Bible is useful to accomplish a certain end—an adequately equipped Christian—because it is the very counsel of God.  Paul’s teaching in 2 Timothy was meant to qualify the nature of Scripture, not to disqualify the usefulness of other material.

      What does “adequate” mean here?  It probably means what adequate usually means, that the man of God has everything that is essential.  Food and air and water are adequate to keep one alive, but their adequacy doesn’t imply that nothing else is beneficial.     Second, the argument proves too much.  The Scripture Paul has in view is the Old Testament, specifically the sacred writings of Timothy’s childhood (note verse 15).  These are what Paul identifies as being able to “give you the wisdom that leads to salvation through faith which is in Christ Jesus.” 

      If the Old Testament Scriptures are adequate, and if Paul means to suggest that the addition of any information about man and his condition is wrong, then how do we justify adding the words of the New Testament to the fully adequate Old Testament?  Even Paul’s words (as well as Peter’s, John’s, etc.) would be inadmissible, including the very words of 2 Timothy 3:16-17 that make this claim.

      Since this is self-defeating, the entire objection crumbles.  Paul did not mean to convey that other sources of knowledge were an assault on the Scripture’s completeness. 

      Some have pointed out that my argument could be used to teach that Paul thought only the Old Testament was inspired, not the New.  Not so.  Paul’s statement was about Scripture, which at that time was what we now call the Old Testament.  He did not say that no more “God-breathed” writings would be forthcoming.  The corpus of Scripture was expanded by the New Testament writers and therefore it’s included under the claims of this verse. 

      The problem only arises if one imposes a foreign sense of adequacy on this passage, i.e., nothing else is allowed.  If we hold that Paul and the Apostles wrote legitimate Scripture, then that proves Paul’s didn’t intend such a restriction.  That’s my point.

 

Proverbs and Wisdom from Nature

      There are other problems with the “Bible only” view.  Scripture itself seems to encourage us to take counsel from other sources of information. In Genesis, for example, God gave a command, but gave no details of how to accomplish it.  The mandate to be fruitful and multiply cannot be fulfilled without the ability of man to observe his environment, learn useful things, and then employ them to improve his condition—all apart from special revelation.

      This is precisely what we find in the book of Proverbs.  According to Solomon, wise counselors are those who are skilled at life, including the ability to observe the natural realm and deduce spiritual truth, moral knowledge, and skills at living.

      Note this statement in Proverbs 24:30-34:

 

I passed by the field of the sluggard, and by the vineyard of the man lacking sense; and behold, it was completely overgrown with thistles.  Its surface was covered with nettles, and its stone wall was broken down.  When I saw, I reflected upon it; I looked, and received instruction.  “A little sleep, a little slumber, a little folding of the hands to rest,” then your poverty will come as a robber, and your want like an armed man.

 

      Proverbs shows that we can draw true conclusions about right conduct through astute observations of the world.  Even before the sage says,  “My son, observe the commandment of your father” (6:20), he says, “Go to the ant, O sluggard.  Observe her ways and be wise” (5:6). 

      In other words, God reveals Himself in propositional form (Scripture) and non-propositional form (nature).  Through observation and reflection on either—if they are properly interpreted—one can infer principles for living because both inform man how to live well.

      Taking his own advice, the sage of Proverbs makes this observation:

  

Four things are small on the earth, but they are exceedingly wise:  the ants are not a strong folk, but they prepare their food in the summer; the badgers are not mighty folk, yet they make their houses in the rocks; the locusts have no king, yet all of them go out in ranks; the lizard you may grasp with the hands, yet it is in kings’ palaces (30:24-28).

 

      Consider this scenario.  When a city is plagued by violence, the people decide to execute murderers.  Immediately the murder rate drops and peace is restored to the city.  These people used their fallen, human wisdom to employ a biblical solution—government bearing the sword to mitigate the impact of evil.  They accurately assess and solve a human problem, even without knowledge of Scripture.  This kind of thing happens all the time.

 

Wisdom from the Heathen

      The Wisdom Literature of the Amenomope is a body of work from the Middle East that pre-dates Proverbs.  It’s of interest because it contains a section of material almost identical to Proverbs 22:17-24:22.  It’s highly probable that the authors of the latter part of Proverbs borrowed this material from the Amenomope and inserted it into the inspired text. 

      Some scholars see this as a serious compromise of the doctrine of inspiration.  However, a more robust (and, I would say, more biblical) view of natural theology removes the objection.  Clearly, natural man apart from God is capable of discerning truth that, according to its use in Proverbs, is from God.

      Paul’s classic teaching in Romans 1:18ff identifies the universal, innate ability to draw conclusions about God’s nature without the aid of special revelation—a capability so effective that the willful suppression of it brings God’s judgment. 

      Keep in mind that the specific details Paul identifies here—“His invisible attributes, His eternal power and divine nature”—are only examples of natural revelation, not the total sum of it.  He doesn’t limit our knowledge to only basic information about God’s existence. 

      In Genesis 18:25, Abraham challenges God’s plan to destroy Sodom and Gomorrah:  “Far be it from Thee to do such a thing, to slay the righteous with the wicked, so that the righteous and the wicked are treated alike.  Far be it from Thee!  Shall not the Judge of all the earth deal justly?”  Where did Abraham get his notion of justice?  It was innate, natural revelation, a moral law built into his humanity.

      One thing at stake here is natural theology—that which can be known about God and about man’s spiritual condition through general revelation.  Can unregenerate man know anything significant without the aid of special revelation?  The Bible seems to teach he can know much.

 

Knowledge from Natural Revelation

      The late Dr. Francis Schaeffer pointed out the Bible is “true truth,” but not exhaustive truth.  It’s completely true about everything to which it speaks, but it doesn’t speak about everything there is to know.  Much more can be discovered.

      Dr. Bruce Demarest, Professor of Systematic Theology at Denver Seminary, makes this observation:

 

      God wills that man, the pinnacle of His creation, should use his reason to secure truth, including elementary truths about himself.  Equipped with an intuitional knowledge of God, including the light of conscience, and enabled by common grace, man by rational reflection on the data of the natural and historical order draws inferences about God’s character and operations.[3]

 

      Man, made in the image of God, gains knowledge based on general revelation.  He has an innate ability to know first principles and basic rules of logic, Demarest argues, and knows how to apply these abilities to learn truth, not just about his world, but also—in a limited way—about the spiritual realm. 

      Demarest concludes, “Scripture supports our thesis that further truth content about God is acquired by rational reflection on God’s general revelation on nature in history.”[4]

      A case in point is Dr. Bernard Nathanson, one of the founders of the National Abortion Rights Action League (NARAL).  Nathanson ran one of the largest commercial abortion operations in the country.  He later repudiated the practice and became an ardent advocate of the rights of the unborn child. 

      Why the change of heart?  Because he became convinced that abortion was a serious violation of human dignity.

      The irony is that Bernard Nathanson made this about face as an atheist (though he is now a convert to Catholicism).  One could argue it’s very hard to justify the concept of human rights—a type of transcendent law—if there is no God.  Nathanson’s reversal, however, proves that it’s possible that even those with faulty philosophical foundations (like Freud, Maslow, Jung, etc.) can reason inconsistently to a conclusion  that turns out to be true.  Nathanson’s thinking was inconsistent with his world view, but his intuitive knowledge of human value—a function of general revelation—was correct.[5]

 

The View of the Reformers

      Even the Reformers, aggressive in asserting total depravity and advocates of sola Scriptura, did not hold to this radical version of “Bible only.”  Note Calvin:

 

      In reading profane authors, the admirable light of truth displayed in them should remind us, that the human mind, however much fallen and perverted from its original integrity, is still adorned and invested with admirable gifts from its Creator....Their example should teach us how many gifts the Lord has left in possession of human nature, not withstanding of its having been despoiled of the true good.[6]

 

      Calvin does not take lightly this “despoiling.”  Regarding spiritual discernment—“the knowledge of God, the knowledge of...our salvation and the method of regulating our conduct in accordance with the Divine Law”—he said that “the mind of man must ever remain a mere chaos of confusion.  To the great truths, what God is in Himself, and what He is in relation to us, human reason makes not the least approach.”[7]

      Calvin distinguished between two kinds of knowledge.  He calls them natural gifts and supernatural gifts.  Calvin holds, with Augustine, that man’s natural gifts were corrupted by sin, but not withdrawn.[8]  He then continues for almost five pages in his Institutes detailing the capabilities of fallen reason. 

      According to Calvin, only man’s supernatural gifts were lost, specifically “the light of faith and righteousness, which would have been sufficient for the attainment of heavenly life and everlasting felicity.”[9]

      Would this great Reformer condemn the contributions of modern psychology as mere worldly wisdom?  No, that’s all part of the natural gifting God has given to man.  Calvin even extols what he calls the “shrewd” observations of Aristotle:  that people have a tendency to acknowledge general moral principles, but go into denial when they personally contemplate committing sin.  Afterwards, guilt and remorse set in.[10]

      Whether one agrees with the particular point or not is incidental.  What is important is that John Calvin—a principal Reformer utterly dedicated to the biblical doctrine of “total depravity”[11]—quotes an unregenerate Greek philosopher on the vicissitudes of the human psyche.  Calvin is using Aristotle’s psychology to help articulate an aspect of man’s fallenness.

 

Adequacy

      The question “Is Scripture adequate?” is much like the question “Is Christ adequate?”  The answer depends entirely upon what one expects either to do.  Each one does something specific for us; neither does everything.  In one sense, God wasn’t even adequate for Adam in the garden.  Though Adam was walking in unfallen fellowship with the Father, God still said, “It is not good for the man to be alone; I will make him a helper suitable for him” (Genesis 2:18).

      The Bible is sufficient to give the “wisdom that leads to salvation” and to enable the godly person to be “adequate, equipped for every good work” (2 Timothy 3:15,17).  Such sufficiency does not preclude other sources of learning that give further instruction in mental health and skill at living.

      The Scripture is the standard of truth to be studied, applied, and cherished.  The Bible itself, however, doesn’t support the “Bible only” view.  It does not teach that man is so distorted by sin as to lose his ability to discover useful truth on his own.  It teaches rather that man has an extensive ability to draw from general revelation making accurate and useful assessments about life and its problems.

      Christians who, however well-intended, promote this narrow view, encourage unnecessary conflict in the church.  They also deny believers a source of wisdom and knowledge from general revelation that the Bible itself encourages us to consider.

[11]“Total depravity” is the accepted term, but I’ve put it in quotes because it’s actually a misnomer, giving the mistaken impression that man is incapable of producing anything good or of value.  Our term “total depravity” actually means that no part of man is untouched and untainted.  The extent of the impact of the fall is total, not the degree.
