What is Apologetics?
First, the english word apologetics is derived from the Greek word apologia.
Apologia; to speak on behalf of oneself or of others against accusations presumed to be false—‘to defend oneself.’
Louw, J. P., & Nida, E. A. (1996). Greek-English lexicon of the New Testament: based on semantic domains. New York: United Bible Societies.
Dr. William Lane Craig in his book ” Reasonable Faith” defines apologetics as “that branch of Christian theology which seeks to provide a rational justification for the truth claims of the Christian faith… Apologetics specifically serves to show to unbelievers the truth of the Christian faith, to confirm that faith to believers, and to reveal and explore the connections between Christian doctrine and other truths.”
1 Peter 3:15–16 (ESV) – Here we see the word “apologia” translated as defense
but in your hearts honor Christ the Lord as holy, always being prepared to make a defense to anyone who asks you for a reason for the hope that is in you; yet do it with gentleness and respect, 16 having a good conscience, so that, when you are slandered, those who revile your good behavior in Christ may be put to shame.
The Apologist: Apologia means to give a defense, not an apology. An apologist isn’t someone who walks around saying I’m sorry – no, that’s what a husband does. An apologist gives good reasons for the Christian worldview and explains how it best reflects reality. The apologist would present the truths of Christ and Christianity in such a way that they make sense and become attractive to people.
