the irrefutable application of logic to doctrine


Theologian and apologist Norman Geisler’s written works span an enormous breadth of Christian thought, yet his conclusions sometimes originate from faulty reasoning and pure speculation. Geisler relies as much on his ability to reason as he does on actual scripture. He often ignores scripture because his reason gives him the conclusion he wants. While obviously sound doctrine requires using human reason, we must always base our conclusions on the truths simply and clearly declared by scripture and separate our selfish human desires from our endeavors.

In his Systematic Theology, Geisler devotes an entire chapter to Logic. In this, he defines and discusses the application of logic to theology. “Logic deals with the methods of valid thinking,” he says.[1] All thinking requires logic, says Geisler.[2] He diligently lays out the laws of logic, including syllogisms, deductive and inductive logic, along with various fallacies and propositions, etc., etc.
If logic is the basis of all thinking, and theology is thinking about God, then it follows that logic is the basis of all thinking about God.[3]
Logic allows us to form arguments, to think about our world, about ideas, and to arrive at conclusions. Patrick Hurley, author of the standard collegiate textbook on the subject, says that logic gives us “the skill needed to construct sound arguments and to evaluate the arguments of others.”[4] Hurley tells us that logic instills the necessary awareness needed for “clear, effective, and meaningful communication.”[5] Hurley does not grant the universal ability to logic that Geisler does. Logic does not form the basis for thinking, but it allows us to evaluate our thinking, at least from a secular reference point. From a spiritual reference, logic can help us avoid errors, but it does not teach us anything. Theology is the study of God, not thinking about him. Finney had thoughts of God, as well as Pelagius, Aristotle, and Plato. Every atheist has thoughts of God. “The fool says in his heart, ‘There is no God,’” says the psalmist (Psalm 14.1). In order to study God, he must draw us to him and reveal himself. Christ said, “No man can come to me unless the Father who sent me draws him” (John 6.44). In the book of Jeremiah, God said, “I will put my law within them and on their heart I will write it” (Jeremiah 31.33). we do not learn about God by our sinful, irrational minds. God has given logic as a tool, yet we are unable to use it to its full advantage without his grace.

Theologians have traditionally relegated the nature of the Trinity to mystery; they do the same with the incarnation of Christ. Logic cannot abide with mystery, and trusting in mystery does not satisfy Geisler. He feels a need to logically confine this mystery in a logical cage. He attempts to explain these divine, incomprehensible, glorious truths and fit them into his ridiculous human vocabulary.
In the Godhead there is one What and three Whos; in Christ, the second person of the Godhead, there is one Who and two Whats. In the Incarnation, one Who in God assumed another What, so that there were two Whats in one Who.[6]
We do not glorify God by attempting to reduce him to colloquialisms of bizarre pronouns and meaningless equations. He is beyond us necessarily and forever so.

Geisler fails to apply his own stated rules in applying logic. He describes deductive logic through syllogisms and propositions. In a syllogism, we define terms, apply a property to the general term, and then single out one example. If the example meets the definition of the term, then the property applies. In Geisler’s example
All human beings are sinful.
John is a human being.
Therefore, John is sinful.
[7]
Syllogisms use propositions. A proposition declares a property of a term.
All human beings are sinful.
Though Geisler states the importance of using propositions in forming theological conclusions, he ignores the propositions he disagrees with. He agrees that human beings are sinful, and that “spiritual death is spiritual separation from God,”[8] yet he denies Paul’s direct statement that the spiritually dead cannot please God. Geisler believes that spiritual death does not mean that humans are so depraved that “they have no capacity to understand and respond to God’s message.”[9] Geisler ignores the statement of Christ, who said that we do not bear spiritual fruit apart from him (John 15.5). He ignores Paul, who said that the spiritually dead mind “is hostile toward God; for it does not subject itself to the law of God, for it is not even able to do so, and those who are in the flesh cannot please God” (Romans 8.6-8). Paul repeats this to emphasize that men cannot believe in God, as God is only pleased by our faith in him (Hebrews 11.6).[10] 

Geisler also illogically uses analogies to prove his point, but analogies do not prove anything. He isolates verses that describe sinners as polluted, sick, and in darkness, and then says, “A sick person is able to receive a cure, just as a dirty person can embrace cleansing and a person in the dark can accept light.”[11] Analogies do not give us information. They do not strengthen arguments or create counterpoints. Analogies merely serve to illustrate proven points. If we found our doctrine entirely on scripture, analogies prove nothing. Scripture uses many metaphors to describe our unredeemed state, and Geisler focuses on only those that validate his position, even though he says in his Logic chapter that inductive logic requires examination of the broadest possible sample of evidence.[12] May I add another logical rule: direct statements are stronger than metaphors. Scripture uses metaphors to clarify and exposit theological concepts, but we speculate dangerously when we extend these metaphors beyond the text.

When Geisler says that sinners are polluted and in need of cleansing,[13] he cites Titus 2.14, which says
[Christ] gave himself for us to redeem us from every lawless deed, and to purify for himself a people for his own possession, zealous for good deeds.
Notice Paul does not say that we are not clean. He implies this. Direct statements are also stronger than implications. We can look elsewhere and find that sinners are unclean (Isaiah 6.5), but we cannot conclude this from this passage alone.

Geisler fails to discuss the interplay between language and logic. Unfortunately, scripture does not neatly state its propositions in proper, logical form, always using categorical syllogisms, propositions, or excluded middles. We must do much of this work ourselves. While Geisler pretends to give homage to clear, rational thought, he makes broad doctrinal statements without clearly laying out the evidence for them. In discussing predestination and free will, he says that “the Bible affirms that human beings are free to accept or reject God’s gift of salvation (John 1.12; Romans 6.23; Matthew 23.37; 2 Peter 3.9).”[14] None of these verses contain a proposition about free will. The concept of free will can only be read into the verses if one assumes a priori that free will is true. We expect a proposition declaring that man is free to accept or reject God to read like this:
Men can freely accept or reject God’s gift of salvation.
John 1.12 says, “As many as received him, to them he gave the right to become children of God, even to those who believe in his name.” We can rephrase this as a conditional statement:
If a man believes in his name and receives him, he gives them the right to become children of God.
Does this declare man’s freedom? Pair it with John 1.13, which says that these who receive Christ “were born, not of blood, nor of the will of the flesh, nor of the will of man, but of God.” If we combine the two verses together and rephrase them as a conditional statement, they in fact deny free will.
If a man believes in Christ’s name and receives him, then Christ gives him the right to become a child of God, and this only because of God’s will, not a man’s will, by his blood, or by his father.
If we state this categorically rather than conditionally, as the text is presented, we have this.
By God’s will alone, we are his children, and God gives his children the right to become his children because they believe in Christ and receive Christ.
Logically, this is nonsense. This can only be revealed to us. We are always his children because he has decided this to be, because we believe in Christ, and we believe because we are his children.
None of these verses declare free will. Romans 6.23 tells us that the wages of sin is death. This tells us nothing about man’s will, but only of the consequences of sin. In Matthew 23.37, Christ laments over the unwillingness of Israel to repent. Unwillingness does not indicate free will if Christ said, “Everyone who commits sin is a slave to sin” (John 8.34); it actually confirms the slavery of the will. Christ gives us the direct statement that we need to begin to logically form theology—Man is a slave—but not the statement that Geisler wants. Peter does not make a statement about free will in 2 Peter 3.9, but instead a statement of God’s desire for all of his children to believe in him. Geisler adds to these passages what he wants to be true. Instead of applying his strict rules of logic, he falls victim to his self-centered desire to be free from God’s sovereignty.

Every Arminian fails in this respect. Instead of asking, “What does scripture teach?”, he says to himself, “This is what I want scripture to teach.” Not a one of them realizes that he is a proud, self-centered human being, and that this is the first and foremost admission he must make before he attempts to know God.
