As a professor of Christian Apologetics at Biola University, I (Sean) help prepare students to answer tough questions raised against the Christian faith. One day someone from outside the Biola academic community called our university to ask why we offer classes on apologizing for the faith. She thought apologetics meant teaching students to say they were sorry for their beliefs! While her question was well intentioned, she didn’t grasp the nature of apologetics and its role in the Christian life. Christians certainly should apologize for their faith, but not in the way she had in mind.
The word apologetics does not mean to say you’re sorry. Instead, it refers to the defense of what you believe to be true. This is exactly what my father and I do in the updated and revised Evidence that Demands a Verdict. We lay out the historical evidence for the Bible, the deity of Christ, the resurrection, and more.
Theologian Clark Pinnock explains the nature of apologetics in this way:
The term derives from a Greek term, apologia, and was used for a defense that a person like Socrates might make of his views and actions. The apostle Peter tells every Christian to be ready to give a reason (apologia) for this hope that is in him (1 Peter 3:15). Apologetics, then, is an activity of the Christian mind which attempts to show that the gospel message is true in what it affirms.
New Testament Examples of Apologetics
The New Testament uses the Greek Word apologia, often translated in English as “defense,” eight times in the New Testament. Consider three examples:
- Acts 22:1: “Brothers and fathers, hear the defense that I now make before you.”
- Philippians 1:7: “It is right for me to feel this way about you all, because I hold you in my heart, for you are all partakers with me of grace, both in my imprisonment and in the defense and confirmation of the gospel.”
- 1 Peter 3:15: “But in your hearts honor Christ the Lord as holy, as always being prepared to make a defense to anyone who asks you for a reason for the hope that is in you; yet you do it with gentleness and respect.”
First Peter 3:15 uses the word defense in a way that denotes the kind of defense one would make to a legal inquiry, asking, “Why are you a Christian?” A believer ought to give an adequate answer to this question. The command to be ready with an answer is directed toward every follower of Jesus—not just pastors, teachers, and leaders.
In other words, every Christian is an apologist. All believers are called to proclaim and defend Christianity. Simply put, although we are not called to say sorry for our beliefs, we are called to “apologize” for them.
