1 Peter 3:15 “but sanctify Christ as Lord in your hearts, always being ready to make a defense to everyone who asks you to give an account for the hope that is in you, yet with gentleness and reverence.”

Defining the term “apologetics”

In the opening text of today’s post we see the mandate given by the Apostle Peter to defend the Christian’s hope.  In fact the word translated “defense” is the Greek word “apologia” (a-po-lo-gee-a), from whence we derive the name of the branch of Christian theology called “apologetics”.  When a Christian engages in apologetics, they are not saying they are “sorry” for being a Christian, rather they are given reasons to skeptical onlookers as to why they are so full of hope in an otherwise hopeless world.  Dr. R.C Sproul in a sermon entitled “apologetics” gives this definition of apologetics: “A well reasoned defense of the truth claims of the Christian faith.” Any well rounded Christian should not only know “what they believe” but also “why they believe”.

Various methods for doing apologetics

With the mandate to defend the faith being clear from scripture and the meaning of apologetics being briefly defined, the next important area has to do with how to go about doing apologetics.  With the upsurge of skepticism and attacks on the Christian faith occuring at a steady pace for the past two and one half centuries, Christian apologists have become more concerned with how one does about articulating and defending Christianity. The below outline is meant to summarize some of the most widely used methods, without tipping the hat to one over the other. It is hoped that the read will at least consider each one and look for ways to defend and communicate God’s truth in a lost a dying world.

a. Classical Apologetics

Ed Hindson and Ergun Caner of Liberty University of the following description of classical apologetics:”the unbeliever is offered evidence of the existence of God, and the supposition is that the unbeliever can reasonably ascertain that this hypothesis is rational and cohesive”. 1  Hindson and Caner then explain further the second area general covered by classical apologetics, namely: “The classical apologist further argues for the reliability of the special revelation (The Bible) as a reliable and authoritative word from God.”2  Author Doug Powell has this to say about the classical method: “The emphasis of classical apologetics is on reason. Christianity’s logical soundness and internal coherence is exploited in this method. As a result, tests are developed and proofs are given that demonstrate the truthfulness of Christianity and the irrationality of competing worldviews.”  Powell later adds: “The classical method is so called because it traces its roots back to the second century and the earliest apologists.”When defending the Christian faith through the method of classical apologetics, at least two and sometimes three steps are followed in the course of the presentation.

1. First, reasonable arguments are given to show the reasonability of the Christian faith. Such arguments as showing God’s existence from observations in the universe and science (i.e the cosmological argument); the existence of objective moral values (i.e the moral argument); how God is necessary for anything to exist (i.e the ontological argument) and then the evidence for design in the universe (also called the telelogical argument).

2. The next phase will usually entail demonstrating the reliability of the Bible from the transmission of its words through the thousands of existing manuscripts to the archaeological evidence supporting the accounts we read in the Bible.

3. Usually the final phase will then be showing how the God of the Bible exists due to the resurrection of Jesus Christ from the dead. Some classical apologists will combine this step and the defense of the scriptures, whereas others may only focus on either one. A fine example of a classical Christian apologist is Dr. William Lane Craig and his website:

b. Presuppositionalist apologetics

Classical apologetics states the the proper starting point for defending the Christian faith is reason to scripture. However other apologists believe that the proper starting point for defending the Christian faith is by pre-supposing God Himself.  Christian scholar Norman Geisler notes: Presuppositional apologetics is the apologetical system that defends Christianity from the departure point of certain basic presuppositions. The apologist presupposes the truth of Christianity and then reasons from that point.With the presuppositionalist approach, the emphasis is almost opposite, namely you presuppose God’s existence and aim to prove why Christianity alone is most reasonable and possess the greatest justification for believing.  Douglas Powell notes the following about presuppositionalism: “Thus, presuppositionalists are more concerned with what makes evidence evidential and what makes reason reasonable. Because the God of the Bible is the Creator of all things, we know that He is not just the source of all physical things, but all laws whether they be scientific laws, moral laws or logical laws.5

The presuppositionalist contends that since all human beings have the knowledge about God in their hearts, the purpose of apologetics then is to expose the fallacies of their worldview and get them to admit what they have been supressing. A typical presuppositionalist approach would be that without God, we could not use reason in our discussions, since reason itself requires the existence of God to operate. The existence of objective moral values and the underlying laws of such fields as math and even science require the existence of God. Even though presuppositionalism is the minority method in apologetics today, it can be very effective when dealing with such worldviews as Atheism. A fine example of a presuppositional apologist is Dr. Greg Bahnsen:

c. Evidential Apologetics

In the evidentialist approach, evidence from the world of the sciences, history and observation functions to provide the necessary ammunition for the Christian apologist. Doug Powell notes: Evidentialism’s value as a substantial tool to defend the faith rose in the nineteenth and early twentieth centuries as archaeology in particular developed as a science and turned its attention to the Mediterranean world and the Middle East. The findings of ancient manuscripts contributed immensely to our ability to know the original text of the Bible.”Hindson and Caner give this insight about the evidentialist approach: “the method is the same: arguing the preponderance of the data.”7

In the evidentialists mind, if enough evidence is brought forth to the unbeliever, the unbeliever will be backed into a corner, admitting that their evidence cannot compare to the evidence for the God of the Bible. In using events such as the World-wide flood of Genesis 6-9, evidentialists will appeal to virtually every branch of science to support the historical reality of the flood. In showing the flood to had been a real event, the logical follows then that the Bible is realiable enough to be trusted in other areas and ultimately salvation. A fine example of an evidentialist apologetic ministry is:

d. Fideism or arguing that the best defense of the Christian faith is the Christian faith itself

Doug Powell observes the following about this fourth major approach: “In sharp contrast to these three methods, fideism rejects reason, evidence, and transcendental arguments as sufficient ways to justify the Christian faith (fide is Latin for faith). Faith and faith alone is the only proper way to understand the truth of Christianity.”8  For the fideist, the task of the apologist is to proclaim the truth of the Gospel in the special revelation of the Bible, since the warped human nature necessarily rejects the testimony of God in the general revelation of creation and the conscience. As Hindson and Caner note about this approach: “A fideist, therefore, is one who holds the view that one comes to belief in God on the basis of faith alone, in the absence of or contrary to reason.9 Unlike the other three viewpoints above, the value of evidence and rational arguments is placed in doubt under the method of fideism. Here is a great link describing this method of apologetics:


We have explored the meaning of apologetics and four main methods for defending the Christian faith: classical, presuppositionalism, evidentialism and fideism. May you and I dear reader know that not only must the Christian hope be defended, but that there are some marvelous ways in which we can go about presenting Christ to a lost a dying world.

About pastormahlon

By the grace of God I was converted to saving faith in Jesus Christ at the age of 10 and called into the Gospel ministry by age 17. Through the Lord's grace I completed a Bachelors in Bible at Lancaster Bible College in 1996 and have been married to my beautiful wife since that same year. We have been blessed with four children, ranging from 7-18 years of age. In 2002 the Lord enabled me to complete a Master of Arts in Christian Thought at Biblical Theological Seminary, Hatfield PA. For nearly 25 years I have been preaching and teaching God's Word and have been studying the original languages since 1994. In 2016 God called my family and me to move to begin a pastorate at a wonderful Southern Baptist Congregation here in Northern New York.
