What is Apologetics?
A reasoned defence
Apologetics is the art of giving a reasoned defence of a belief system or person. It’s about explaining and defending what we believe and why we believe it. Here at OCCA the Oxford Centre for Christian Apologetics, we want to use apologetics to form a compelling case for the Christian faith and the person of Jesus.
The word apologetics derives from the Greek word ἀπολογία (apologia) which entails giving an answer, defence or reply, much like a lawyer might give in a courtroom.
What does Apologetics mean in the Bible?
A foundational verse in the study of apologetics is 1 Peter 3:15 (NIV); ‘But in your hearts revere Christ as Lord. Always be prepared to give an answer (apologia) to everyone who asks you to give the reason for the hope that you have. But do this with gentleness and respect’.
Biblical apologetics is about giving a reason for hope in Jesus.
This verse also highlights the importance of character in apologetics; gentleness and respect are key in the instruction for Christians to engage in this form of conversation.
While apologetics can take many forms, four key themes help us to understand it’s main purpose; clarification, investigation, communication and introduction.
Why does apologetics matter?
Apologetics has a role to play in responding to people’s questions and concerns about the Christian faith. Justin Martyr is known as one of the first Christian apologists[1]. His first apology, written around AD 150, responds to many misunderstandings about Christianity that were prevalent in the culture; for instance what was actually happening in a worship service and the relationships between believers who called each other ‘brothers and sisters’. The role of apologetics is much the same today; bringing light and truth to common misconceptions about the Christian faith. For example, many people think that when Christians are talking about faith, they mean blind faith i.e. faith without, or in spite of evidence.
Apologetics can serve to clarify that faith can be based on reason and experience.
What does apologetics cover?
Beyond just clarifying misunderstanding, apologetics can help people investigate the key claims of Christianity in more detail. Apologetics is an exploration of the big questions of life, and what Christianity might have to say to them.
Questions of meaning, suffering, longing, hope and the nature of reality all come under the umbrella of apologetics.
The Christian story, if true, should speak to every area of life. Apologetics is about investigating that claim. This might take the form of rational, philosophical arguments, but it can also be relational, emotional and imaginative investigation.
How is apologetics shared?
Thirdly, apologetics is about communication. German theologian Helmut Thielicke said that “The gospel must be preached afresh and told in new ways to each generation, since every generation has its own unique questions”[2]. When giving a ‘reason for the hope that you have’, it is central that this is communicated in a way that is understandable. OCCA runs courses to help people think through these big questions and in turn speak into them with gentleness and respect[3]. To find out more click here.
Big questions of life and faith are rarely asked in a vacuum; people need to know how these questions make sense of their lived experience. Apologetics is about communicating the hope of Jesus in a way that answers each generation’s unique questions.
Pointing to Jesus
Finally, apologetics is about an introduction to the person of Jesus. Whilst rational arguments and reasoned defence is important, it is not the landing point of apologetics. The Christian claim is that truth is not impersonal, it is a person. Jesus describes himself as the truth[4]. Apologetics can often have a different starting point to theology. Christian theology often begins within a faith tradition and explores questions more deeply. Apologetics often begins with the questions, doubts or experiences that people bring in to a conversation. The entry to apologetics could be poetry or philosophy, art or objections.
The landing point of both disciplines, philosophy and theology, is in the person of Jesus.
In John 1, we are introduced to the Word, the Logos (λόγος). Logos is the Greek word from which we derive our word logic. This logos does not stay removed from us, but takes on flesh and makes his dwelling among us[5] as the person of Jesus.
Apologetics is about giving a defence for the truth, beauty and goodness of the good news of Jesus Christ. Aiming to clarify where there is misunderstanding, investigate the big questions of life and faith, communicate this news plainly and accessibly and ultimately introduce people to the person of Jesus.
