Q: What is the "classical" approach to apologetics and what are its strengths and weaknesses? How does this approach stack up against the presuppositional approach?
Classical
apologetics is a two step approach to arguing for the Christian world
view. First it argues for a god, and
after offering what it views as satisfactory arguments, it then progresses to
arguing for the Christian triune God.
There
are some positive aspects of classical apologetics. It seeks to show that faith and reason are
consistent, which is a noble aim and has been of service to countless
believers, buttressing their faith. Also
the classical approach historically has been at the forefront of the apologetic
efforts of the church as the preferred method of many staunch defenders of
orthodoxy like Augustine, Hugo Grotius and B.B. Warfield. That said, while I love and respect many who
hold to the classical apologetic method, I don’t think that it is the best
approach to defending the Christian faith.
Classical
apologist William Lane Craig describes the classical apologetic method as
“first to present arguments for theism which aim to show that God’s existence
is at least more probable than not and then to present evidences,
probabilistically construed for God’s revelation in Christ.”
While there are a number of methodological
problems with this approach, this statement reveals the chief (and fatal) flaw
with the classical approach to apologetics.
Apologetics is, at its root, an evangelistic enterprise, and souls are
at stake. In that context “more probable
than not” is simply not good enough.
When engaged in this kind of encounter we must show with certainty that
Christian faith is the only right world view.
Another
key problem with this two step approach to apologetics is it leads the door
open for an unbeliever to accept a theistic world view yet reject
Christianity. A person may acknowledge a
god yet still deny the existence of God and thus be as lost as any
atheist. This in fact happened to noted atheist Antony Flew who at the age 81 announced that the teleological argument
for God convinced him that there must be a super-intelligent creator. However he did not become a Christian, but
rather a deist, and thus still died in his sins.
This
is not surprising. One of the most
popular arguments for theism used by classical apologists is the Kalam cosmological argument (which essentially states that everything observable has
a cause, there cannot be an infinite chain of causes thus there must have been
an uncaused cause and that the uncaused cause must be God). This argument however was not formulated by
Christians, but by Islamic philosophers, so clearly classical apologetics leaves
the door wide open for deviant theism which does not save but condemns. Moreover if the God of the Bible is not
presupposed there is no justification for holding to the universality of the
laws of causation. Apart for His created
order there should be no expectation of any universal truths.
Craig’s
approach also reveals a faulty and dangerous prosuppositional basis for his
method; he writes “A good deductive argument will be one…whose premises are
both true and more plausible than its contradictories.” And after describing his preferred argument
concludes “that to deny this proposition is therefore for a normal adult
irrational.” The revealed presupposition
is that man’s reason determines what is true, however such an approach fails to
take into account the noetic effects of sin and the fall and ignores clear
teaching of scripture such as Jeremiah 17:9 which states “the heart (the seat
of reason, not merely emotion in biblical thinking) is deceitful above all
things.” Although most classical apologists
would deny it, their approach functionally
elevates human reason far too high, to a magisterial level.
And
flowing out of this elevation of human reason is a dangerous tendency to
accommodate scripture to the findings of science. The great problem with doing this is that
while scripture is infallible science is fallible, and while scripture is
unchanging scientific theories are constantly being overthrown. Science has time and again proven itself to
be unreliable while Scripture is unchanging and always reliable.
A
practical outworking of this tendency is that many notable classical apologists
such as Craig and Norman Geisler advocate an “old earth” theory of the age of
the earth. This is a clear example of
the elevation of the reasoning of man above the revealed truth of Scripture and
must be condemned. (It must be noted that some classic apologists, such as R.C.
Sproul hold to a young earth and a literal six day creation.)
There
also seems to be a misunderstanding of the work of the Holy Spirit on the part
of some classical apologists. They
readily recognize the value of the internal testimony of the Spirit to
believers and root their “knowing” of the truth of Christianity in His
testimony, however when it comes to “showing” the truth of Christianity they
dismiss the power of the work of the Spirit though the inspiration of the
Bible. Leading classical apologist
William Lane Craig takes misunderstanding the role of the Spirit a step
further, stating that the Holy Spirit will convict the unbeliever of the weight
of the evidence for Christianity. There
is simply no biblical warrant for this assertion however. The role of the Spirit in the unbelieving
world is to convict of sin and the coming judgment (John 16:8) not to help
unbelievers weigh evidential arguments and reach conclusions based on their own
reasoning. While Craig’s position may
not be universally held, it is illustrative of the kinds of errors that can
arise when arguments are not rooted firmly in scripture.
And
aside from a too high view of man’s reason classical apologetics has too low a
view of scripture. By conceding
“neutral” ground to the unbeliever and recognizing a need to argue for the
existence of a God and then the Christian God, it not only operates according
to the presuppositions of the unbeliever, but also disregards the clear
teaching of Scripture that all men have a knowledge of God (Romans 1:18-21).
For
these reasons I believe that classical apologetics should be avoided and that a
presuppositional approach is best. We must always be cognizant that the Word of God is not only infallible and inerrant, but also living and active. When giving an answer for the hope that is in you the revealed truth of scripture is all sufficient, and there is no need to argue for the probability of a God before sharing the truth of Christ.
