Most people have experienced disagreement. When we disagree, there are several ways we can engage those who hold different views. Before proceeding, however, it is important to acknowledge that people do not typically arrive at their beliefs through detached analysis of facts and logic alone. As Jonathan Haidt has argued, we often intuit our beliefs first and then use reason to justify them afterward. Reason serves as the mind’s press secretary more often than its judge.
This does not diminish the importance of logic, evidence, or truth-seeking. Neither Haidt nor I am advocating postmodern skepticism. Rather, it reminds us that people are not machines into which we can input data and expect a predictable output. Persuasion requires more than argument. It requires helping people meaningfully connect with an idea so they can genuinely consider it. With that in mind, we can examine how disagreement is typically conducted.
Generally, discussions fall into three categories: apologetics, irenics, and polemics.
Apologetics, from the Greek word for “defense,” is the reasoned defense of a belief. Christian apologetics follows the command of 1 Peter 3:15-16 to give a reason for the hope within us.
Polemics, by contrast, involves attacking or refuting an opposing belief or practice. Its purpose is to demonstrate why an idea is false or harmful.
Irenics seeks common ground and reconciliation. Whenever we emphasize agreement and shared concerns, we are practicing irenics.
Of these three approaches, apologetics and irenics are generally viewed favorably, while polemics often carries negative connotations. Let’s consider whether polemics deserves a more positive evaluation and whether neglecting it weakens our ability to defend truth.
Biblical Support for Apologetics, Irenics, and Polemics
For Christians, the primary question is not merely what works but what is biblical.
The case for apologetics is straightforward. 1 Peter 3:15-16 explicitly commands believers to defend their faith. Whether people welcome that defense is another matter, but the mandate remains.
Irenics also finds biblical support, though it comes with important cautions. Scripture warns believers not to participate in “the unfruitful works of darkness” (Eph. 5:11) and not to be unequally yoked with unbelief (2 Cor. 6:14). These passages remind us that the pursuit of common ground must not come at the expense of truth.
At the same time, Paul provides positive examples of irenics. In Athens, he begins with the Athenians’ altar to an unknown god, using it as a point of contact without affirming their paganism. Likewise, in 1 Corinthians 9:22, Paul writes, “I have become all things to all people, that by all means I might save some.” Both examples demonstrate the value of finding common ground while remaining faithful to the truth.
Apologetics and irenics therefore enjoy strong biblical support, provided they do not require moral or doctrinal compromise.
The Case Against Polemics
Polemics is more controversial.
One reason is its association with winning arguments rather than discovering truth. A purely combative or Machiavellian approach is incompatible with Christian ethics, which require believers to speak the truth in love.
A second concern is its connection to personal attacks. Ad hominem arguments attack individuals instead of addressing ideas and are rightly recognized as fallacious.
Third, polemics is often associated with unnecessary aggression. Scripture commands Christians to respond with gentleness and respect (1 Pet. 3:15-16) and to correct opponents with patience (2 Tim. 2:25-26). Excessive aggression may harden opponents and alienate observers.
Nevertheless, being offensive and causing offense are not the same thing. Truth sometimes offends. If an idea is false, harmful, or contrary to the gospel, Christians must be willing to say so. Evangelism itself requires telling people that they are sinners in need of salvation, a message many will find uncomfortable. The possibility of offense cannot determine whether truth is spoken.
The Biblical Case for Polemics
Despite these concerns, Scripture contains numerous examples of polemical engagement.
Paul’s letters to the Corinthians and Galatians directly attack false teachings and those promoting them. In Galatians 5:12, Paul expresses his wish that the circumcision advocates would “emasculate themselves.” Jude likewise contains sharp denunciations of false teachers.
The example of Jesus is even more striking. In Matthew 23, He repeatedly condemns the scribes and Pharisees as hypocrites, whitewashed tombs, and sons of hell. In Matthew 22:29, He tells the Sadducees that they know neither the Scriptures nor the power of God.
These passages demonstrate that there is a time and place for direct, forceful criticism of error.
When Polemics Is Appropriate
The biblical examples reveal several important principles.
First, there are times when error must be exposed plainly. Christians are not neutral regarding truth, and pretending otherwise can appear dishonest. Sometimes it is insufficient merely to propose a better alternative. Some ideas are genuinely destructive and should be identified as such.
Second, circumstances matter. Jesus did not treat sincere seekers the same way He treated hardened religious leaders. Paul distinguished between those who were deceived and those doing the deceiving. Wisdom is knowing when a gentle explanation is needed and when a public rebuke is necessary.
Third, people differ. Some individuals respond well to careful reasoning and patient dialogue. Others are so committed to a mistaken position that they must first recognize the seriousness of the error before reconsidering it. Effective communication requires understanding the audience.
Conclusion
Apologetics, irenics, and polemics are all legitimate rhetorical tools. Each has a proper place, and each can be misused. The goal is not to use one approach exclusively, but to employ the right tool at the right time.
At times we must defend the truth through apologetics. At other times we should seek common ground through irenics. And sometimes we must expose and refute error through polemics. Often all three approaches work together.
Whatever method we use, our goal must never be merely to win arguments, display intelligence, or embarrass opponents. Our aim is to glorify Christ and lead people toward Him. With that goal in mind, Christians should be willing both to defend the truth and, when necessary, to challenge the arguments raised against it, taking every thought captive to obey Christ.
