The Meaning of Apologetics
What is Apologetics?
Apologetics isn't about apologizing for your faith — it's about being able to explain why you hold it. Apologetics is derived from the Greek word “apologia,” which can be translated as “defense” or “vindication”. The word “apologia” was originally used of a speech of defense or an “answer given in reply”. One of the most famous early uses of apologia appears in Plato's Apology, where Socrates is depicted defending himself against criminal charges of preaching strange gods.1
The New Testament uses the noun form (apologia) and the verb form (apologeomai) 18 times.2 Still, the most common use known today is in 1 Peter 3:15, where Peter admonishes believers to always be ready to “give a reason” for their faith.
Succinctly defined, apologetics is the rational3, philosophical4 defense of a person, thing, or worldview. Christian apologetics then is the rational, philosophical defense of the Christian worldview as objectively true, providing proofs for its plausibility and coherence, defending against criticisms from other worldviews, showing its superiority to other worldviews, and persuading the recipient of the apologetic message5. This definition, as we'll see, contains four distinct functions of apologetics. A simpler definition is: Christian apologetics is the rational, philosophical defense of the Christian worldview.
From the first definition of Christian apologetics6 above, you could probably infer that apologetics isn’t directed at unbelievers alone7. There are two different audiences of apologetics, meaning that apologetics has two different goals:
1. Internal apologetics: the aim here would be to strengthen the faith of Christians, presenting reason for holding to some doctrines in Christian theology, and clearing confusions or doubts about them. This would involve things like explaining the rationality of the Trinity, analyzing the different models of the Trinity (this would be the subject of a later writing), explaining the doctrine of the Incarnation and so on. This might sound no different from doing theology, and that’s because apologetics draws heavily on theology, though as Groothuis notes, it isn't reducible to it:
Apologetics is linked to theology, philosophy, and evangelism, but it is not reducible to any one of these disciplines. The conceptual content8 of apologetics depends on theology, the goal of which is to systematically and coherently articulate the truth claims of the Bible according to various topics, such as the doctrine of God, salvation, and Christ.9
2. External apologetics: the aim of this is to remove obstacles preventing nonbelievers from receiving the gospel. These involve things like arguments for the existence of God (although this is also included in internal apologetics, the difference is that the purpose of giving an argument for God’s existence to a believer is to give him a reason for why he already believes while doing the same to a nonbeliever would be to give him a reason to move from unbelief to faith).
Functions of Apologetics
The definition of apologetics I gave earlier contains the functions of apologetics. They are:10
Apologetics as proof.
Apologetics as defense.
Apologetics as refutation of opposing beliefs.
Apologetics as persuasion.
Apologetics as Proof
Apologetics as proof involves putting forth philosophical arguments as well as scientific and historical evidence for Christianity. The goal here is to develop a positive case for Christianity as a plausible and coherent worldview. This would involve things like giving arguments for the existence of God, such as the teleological, ontological, and cosmological arguments, etc.11 It would also involve arguments more specific to the Christian worldview, such as arguments for the Incarnation, the Trinity, the resurrection of Jesus, the possibility of miracles, etc. It is also called positive apologetics.
Apologetics as Defense
This function of apologetics is closest to the usage of the word “apologia” in the New Testament. It involves defending Christianity against the criticisms of other worldviews. It involves answering objections and clearing obstacles to faith. It aims to show not just that Christianity is true, but that it’s credible. It involves responding to arguments such as the problem of evil (which I think is the strongest argument from atheists against Christianity). It is also called negative apologetics.
Apologetics as a Refutation of Opposing Beliefs
Here, the focus is not on answering objections to the Christian faith, but on attacking other worldviews. For atheism, it would critique unbelief. For Islam, it would critique the status of Muhammad as a prophet and the authenticity of the Quran. Refutation of opposing beliefs can serve both internal and external apologetic functions. If a believer is drawn towards Islam, an apologetic refutation of Islam would be an internal apologetic approach.
Apologetics as Persuasion
The focus here is on bringing non-Christians to the point of believing the gospel. As earlier stated, the main aim of apologetics to nonbelievers (external apologetics) is to bring them to Christ.
In future articles, we'll cover more topics on apologetics.

apologia: Acts 22:1, 25:16, 1 Cor. 9:3; 2 Cor. 7:11; 2 Tim. 4:16; Philippians 1:7,16; 1 Pet, 3:15.
apologeomai: Luke 12:11, 21:14; Acts 19:33, 24:10, 25:8, 26:1, 26:2, 26:24; 2 Cor. 12:14; Rom. 2:15.
Governed by logic, reason, and sound judgement.
Apologetics necessarily requires engaging philosophical topics like Epistemology, Metaphysics, and Ethics; these would be explained in later writings.
If he or she is a nonbeliever. The ultimate aim of apologetics to nonbelievers is conversion.
From here on, my use of the term “apologetics” means “Christian apologetics”.
The fact that you, who are reading this, are a Christian (I presume) tells you something.
“conceptual content” means the ideas and claims apologetics works with. The propositions it makes.

Note that these arguments do not prove the existence of the Christian God or the truth of the Christian worldview. They only serve to prove the existence of God.
