Episode Details

I did some training with the CBS staff recently on ‘apologetics’, and how it relates to ‘evangelism’. And as I did so, I realised that one of our problems is simply that the word ‘apologetics’ gets used today to refer to such a range of different things.

And so to clear the ground a little and clarify understanding, I put forward the following ‘seven kinds of apologetics’. Or perhaps it would be more accurate to say, ‘Seven kinds of Christian speech or interaction that are sometimes called apologetics’. 

See what you think. 

Seven types of ‘apologetics’

What is apologetics? 

Let’s start by saying that apologetics is not evangelism. Evangelism is the proclamation and explanation of the historical truth of the gospel—that God sent Jesus Christ to die for our sins, that he raised him from the dead to be the Lord and Judge of God’s eternal kingdom, and that he now calls on all people everywhere to submit to Christ in repentant faith (see Boxes 4-6 of Two ways to live!). 

But gospel proclamation, pure and simple, is not the only kind of interaction we have with people. There is also conversation and reasoning and debate—both pre- and post-evangelism—and we have come to label much of this ‘extra-evangelistic’ interaction as ‘apologetics’. 

I’m not sure how far the word ‘apologetics’ can actually stretch. In fact, strictly speaking, I think only two of the seven kinds of interaction I’m about to outline are really ‘apologetics’ per se. That doesn’t mean that the other five aren’t valid or useful. They mostly are. But some clarity will help—especially since a common tendency is for apologetics to expand and colonise the space where ‘evangelism’ should be. (But more on that below). 

To conceptualize these seven kinds of ‘apologetics’, I’m going to use the ‘moving to the right’ concept that we looked at a few editions ago—or at least the left half of that diagram which focuses on engaging and evangelizing non-Christian people to move them to the right, towards coming to know and trust and serve Christ. 

Like this:

The different kinds of ‘apologetic’ interactions we’re looking at occupy different points along this spectrum. Types 1-3 are in the ‘evangelize’ zone, and types 5-7 are more down the ‘engage’ end of things, and type 4 is over in the ‘Christian’ zone. It’s never as neat as that in actual conversation, or in the sermons we preach. But categorizing them in this way can help us understand what we’re doing when and why.

1. Persuasion

When we’re right in the middle of evangelism—of actually explaining the meaning of the death and resurrection of Christ—we will provide various arguments and reasons to support our proclamation. Like Paul, in 1 Cor 15, we may argue that the meaning of Christ’s death and resurrection is grounded in God’s age-long plans as revealed in the Scriptures, or we may support the truth of the resurrection by pointing to the witnesses who saw him. (Interestingly, Peter’s sermon at Pentecost covers much the same ground.) Or we may spend time persuading people of the nature and reality of their sin, and their plight before God, as a means of explaining why the death and resurrection of Christ is such wonderful news. 

Reason, argument, persuasion—these are natural aspects of explaining and commending the gospel. We see the apostles and evangelists doing this often and in different ways in Acts (e.g. Paul’s ‘reasoning’ and ‘persuading’ in Acts 18:4 and 19:8). 

Is this ‘apologetics’? Well perhaps not as such, although sometimes it comes close. That’s because ‘apologetics’, strictly speaking, is a defence of something or someone. An ‘apologia’ is your answer to someone’s objection or accusation (this is what the word means). 

If you’re explaining to someone why your message is true and trustworthy, are you ‘defending’ it? Well, sort of. It’s interesting that Paul’s ‘defence’ (ap
