11 Self-Refuting Arguments Against Christian Truth

If you publicly express your faith in Jesus, you will undoubtedly face challenges to your beliefs. This should not surprise us because Jesus told us this would happen. Thankfully, for those of us in the United States, most of these challenges are only verbal in nature. Many of our brothers and sisters in Christ around the world face threats to their property and lives. Wherever we find ourselves, Scripture calls us to be prepared to give an answer for the hope that is in us, and that answer is always, Jesus.

The context in which we must give that answer will vary. For those of us facing intellectual challenges to our faith, we must be ready to expose fallacious arguments as well as give them the gospel. With that in mind, here are 11 common self-refuting arguments. I will break them down into three categories

Truth is relative.

Whenever someone claims that truth is relative, it is important to remember that that would apply to their statement as well. The statement, “truth is relative” would also be relative. This would make their statement about the relativity of truth just as true or false as any of your statements. Thus they lose all authority to speak. Here are a few ways this argument presents itself.

1. Language cannot communicate truth.

Postmodernism has taken root, not only in secular society, but in more liberal denominations as well. About 10 years ago, it was called the emergent church. Though that name has died, these ideas are still infiltrating many churches. Postmoderns argue that language is an invention of man and therefore cannot communicate truth, but they always try to communicate it using language.

2. Propositions are not truth.

The idea with this argument is that experience is truth, not words. This is a clear attack on the word of God. The funny part is, they often try to use the word of God to defend their point, which, of course, would only work if the word of God can communicate propositional truth.

3. There are no metanarratives

This idea that truth is relative leads them to believe that there are no metanaratives. There is no one story that controls all other stories. There are no universal beliefs through which all people should be viewed like creation, fall, and redemption. They believe all metanarratives are a masked play for power. This, of course, is the one overarching story they use to control all other stories. It is the lens they universally apply to everyone else.

4. Christians should not disagree about doctrine.

Their belief in the subjectivity of truth leads them to downplay biblical doctrine. From here, they argue that Christians should not disagree about doctrine. The problem is that this is a doctrinal disagreement they are having with you. Let’s not be naive, doctrinal disagreement can go too far, but to censure all doctrinal discernment leaves the arguer with only one option: to close their mouth and nod in agreement to everything you say.

5. Humans are prone to error so they cannot be trusted.

Finally, you will sometimes see another self-refuting argument in the way they try to justify their belief that truth is relative, but every argument comes back to haunt them. Every time they use the fact that man can err to make everything untrustworthy, they make themselves untrustworthy.

Do Not Tell People How to Live

6. Morality is subjective.

A second area were people often refute themselves is when they argue that morality is relative, and that we ought not tell people how to live. What they fail to realize is when they say “we ought not tell people how to live” they are telling people how to live.

7. Do not judge.

The “Do not judge” argument is probably the most common version of this argument. Of course, if you misinterpret Jesus’ words to mean you have no right to tell people when they they wrong, you refute yourself because you are telling someone they are wrong.

Everything Must be Proven with Science

There are people who take the benefits of scientific inquiry and try to make it the sole source of truth, but they fail to realize that there is a philosophy of science which must under gird all scientific endeavors. Here is how a few of these arguments present themselves.

8. Everything must be empirically proven.

When someone says you should only believe in things that can be experienced with the five senses, realize, their theory cannot be experienced or proven with the five senses.

9. Science is the only source of truth.

Never forget, science itself depends upon immaterial realities like the laws of logic, mathematics, time, and space.

10. Metaphysics are a waste of time.

This one is a little more sophisticated, but it suffers from the same problem. Metaphysics, according to the dictionary, is the study of first principles. These first principles include abstract concepts such as being, knowing, substance, cause, identity, time, and space. Often, as a Christian, when you begin delving into these topics, you will hear this argument from naturalists. The problem, for them, is that they make this statement because of there naturalistic metaphysical pre-commitments to these questions.

11. Humans are programmed by natural selection.

Finally, let us not forget that the naturalist often considers themselves free thinkers because they do not buy into “superstition,” but their own views of a closed system of cause and effect means that their own thought is the product of a closed system of cause and effect just like everyone else’s. The only conclusion that can be drawn from a closed system of cause and effect is determinism, and determinism leaves no room for freedom.

As Christians, let us be aware of fallacious arguments, but more importantly, let us stay close to our Savior and His word. The goal of apologetics is to help clear the intellectual impediments to the gospel, but if we never give them the gospel, or if we are not living close to our Lord and His word, we might as well not do apologetics at all. Though apologetics is helpful and important, it does not save the soul. Faith comes by hearing, and hearing by the word of God.
