• Apologia - From the Greek word meaning "speaking in
defense" or "In defense of."

• The difference between "knowing" and "showing."
• What counts as Christian apologetics? - Any attempt to
defend Christian theism.
The 21st
Century
Understanding

we got here
Criticisms
• Fideism - The position that belief should be maintained on
the basis of "blind faith." (Response - C.S. Lewis - cliff
diving explanation of faith - Lack of biblical support for
fideism)
• What about the Holy Spirit? (Response - Knowing vs.
Showing)
• Examples of Fideists - Kierkegaard, Pascal, Wittgenstein
and William James have all been referred to as fideists.
Modern Methodologies
• Classical
• Evidential,
• Cumulative Case,
• Presuppositional and Reformed
Epistemology
Purpose of Varying Methods
• Doctrinal differences
• Practical differences
• Environmental differences
• Differences of intent
• Evangelistic differences
Classical Apologetics
• Influential characters - William Lane Craig, R.C. Sproul,
Norman Geisler, Stephen T. Davis and Richard
Swinburne.
• Explanation of approach - Classical apologetics is a two-
step method which seeks to 1. demonstrate the existence
of God (theism) and then attempts to 2. demonstrate the
truth of the resurrection or divinity of Jesus (Christianity).
• Criticisms - Man cannot rationally know God, the theistic
proofs are unnecessary, the arguments are not persuasive.
Evidential Apologetics
• Influential characters - Gary Habermas, John Warrick
Montgomery, Clark Pinnock, Wolfhart Pannenburg, Josh
McDowell, and Mike Licona.
• Explanation of approach - Evidential apologetics is a one-
step method which seeks to demonstrate the resurrection
or divinity of Jesus. It may include supplementary
material which helps demonstrate life after death.
• Criticisms - Man cannot rationally know God, the
resurrection cases fail if God's existence is not established,
the arguments are not persuasive.
Cumulative Case Apologetics
• Influential characters - Paul Feinburg, Basil Mitchell, C.S.
Lewis, and Stephen Evans.
• Explanation of approach - Cumulative case apologists seek
to demonstrate the truth of Christian theism by using a
variety of evidences which may or may not be arguments,
strictly speaking. They are not typically defended tooth
and nail.
• Criticisms - Man cannot rationally know God, the "leaky
buckets" challenge.
Presuppositional Apologetics
• Influential characters - Cornelius Van Til, Gordon Clark,
Greg Bahnsen, and Francis Schaffer.
• Explanation of approach - One must accept the axioms
that God exists and has spoken through Scripture in order
to make sense of the world. Presuppositional apologists
will often point out that when an unbeliever argues
against Christian theism he is using christian theistic
principles to make his case. Sometimes the apologist will
compare presuppositions with the unbeliever.
• Criticisms - Circular reasoning, and fideism.
Reformed Epistemology
• Influential characters - Kelly James, Nicholas
Wolterstorff, George Mavrodes, William Alston, and Alvin
Plantinga.
• Explanation of approach - These apologists will point out
that the belief in Christian theism is "properly basic." Man
has internal grounds for belief because God may have
revealed himself via the Holy Spirit or "sensus divinitatis."
• Criticisms - Fideism, the "Great Pumpkin" objection.
Apologetics
in the New
Testament
Developing a
Biblical
Foundation for
Christian
Apologetics
Apologetics
Implicit vs. Explicit
• Implicit: “. . . it is sufficient to affirm at the outset
that a careful study of the New Testament throws
considerable indirect evidence on the way in which
the infant church carried out her apologetical
encounter with Judaism, with paganism, and with
deviant tendencies that arose within the Christian
community.” – (Avery Dulles, I)
• Explicit: 2 Corinthians 15, 1 Peter 3:15, Acts 17,
Romans 1:18-20.
Faced with Questions
It seems clear from the way New Testament authors
wrote that early Christians were faced with questions
such as:
• Where is the Messiah now?
• If Jesus was the Messiah, why was he not accepted by
the Jewish leaders?
• Why was he “hanged on a tree?”
• Why didn’t Jesus foresee the betrayal by Judas?
• When did he even claim to be the Messiah?
Jesus and Evidence
Certainly, Jesus defended his claims in the typical
challenge and riposte of his day. This was like a
miniature academic debate.
The miracles served as evidence of the veracity of His
message. Nevertheless, Dulles summarizes, “Jesus
Rebukes those who demand extraordinary signs as a
condition for faith in him and praises those who
believe in simple reliance on His Word. Yet, He insists
also that the signs He works are such as to increase
the culpability of those who, having seen His works,
still refuse to believe (Mt. 11:20-24; Jn. 15:24).” –
(Dulles, 11)
Paul
Romans 1:18-20: Facts about God (including
certain attributes) can be known from observing
the natural world.
Acts 17:16-34: Reasons that the one true God
(“The Unknown God”) is the creator of all things.
Claims that God furnished “proof” of the
resurrection.
1 Corinthians 1:18-25: The world’s wisdom and
philosophy is insufficient.
1 Corinthians 15: The proof of the resurrection by
early church creed, and eyewitness testimony.
Peter: 1 Peter 3:15
1) Peter mandates that Christians be ready to defend
their faith.
2) Peter implies that it is likely that believers will have
an opportunity to defend their faith.
3) Peter defines the proper attitude of the believer
when approaching the apologetic event.
The Gospels
Matthew: Because this was written in a context in
which Jews were still geographically close, it contains
explicit apologetic material relating to the messianic
prophecies.
Mark: Simply presents Jesus as the early church
knew Him.
Luke: Political and theological apology. It is also a
history of the blossoming church.
John: Written to build up the belief of converts
(possibly to serve some evangelistic purpose).
Hebrews
Hebrews serves as an apologetic work aimed at
the truth of Christianity in light of the ongoing
temptation to resort to Judaism. There are three
clear concerns the author deals with:
1) How could the religion of Israel be overshadowed
by Christianity?
2) Why was Jesus so persecuted if he was the
messiah?
3) How could there be no sacrificial system?
The
Patristic Era
Carving Out a
Place for
Christianity
Reasons to Defend
Dulles gives four types of people that necessitated a
defense after the first quarter of the 2nd century.
Converts: Well educated converts wanted intelligent
answers to tough questions
Philosophers: Rigorous argumentation was
presented from trained philosophers
Emperors: Political apologetics needed to be given
for tolerance of the Christian religion
Jews: Jews were still challenging the “new” faith.
1st-2nd Cent.:
Aristides of Athens
(Died 134 ad)

Antoninus Pius & Lucius Commodus.
Argues that even if Christians are wrong
they aren’t dangerous and shouldn’t get
the death penalty.
Second Apology is a case that there is
value in philosophy no matter where it
comes from and those who come to truth
via philosophy are Christian without
realizing it.

response to the Jews, and contains
Justin’s testimony of embracing
Christianity after reviewing the messianic
prophecies.
2nd Cent.:
Athenagoras
(133-190 ad)
Works: Embassy for the

doctrine of the resurrection.
2nd Cent.:
Theophilus
(Died around 184 ad)
Syrian Bishop of Antioch, who wrote
primarily to urge his close friend
Autolycus to embrace Christianity.
Greatly impressed with Moses.
Said the Genesis account was the
only reliable guide to human origin.
Taught a “theology of the heart.” If
you’re heart is open to God, you’ll
find Him. If it isn’t . . . You won’t.
Letter to Diognetus
• “the Pearl of early Christian apologetics. . .”
• Uncertain authorship and date.
• Probably during 120-210 ad.
• Addresses three questions: 1) How can Christianity reject
other gods and traditions? 2) What is the secret of
Christian brotherly love? 3) Why didn’t Christianity
appear earlier?
• Concepts: Christians are at home and are strangers
wherever they go. “Christians are to the world what the
soul is to the body.”
Examining the
2nd century apologists
• Defensive and Aggressive – “The work of the
second-century apologists, reflects the vigor and the
inconsistencies of youth.” – Dulles Pg. 36.
• Strong cases for religious tolerance.
• Show the weaknesses of pagan worship and
demonstrate how the proper view of God leads to
morality and love.

compare religions than develop proofs of
Christianity.

The
Middle Ages
Developing
arguments for the
Truth of the
Christian
Message
Reasons to Defend
Islam: In the east, Islam was becoming a serious
religious and military force. The apologists of this era
needed to respond.
Judaism: In the west, Jews were still criticizing
Christianity. Apologists needed to continue their

The
16th-18th
Centuries
The Truth of the
Word and How to
Know Christianity
is True
Reasons to Defend
The period of the reformation was a time of far less emphasis on
what we would think of as apologetics (the demonstration of the
truth of the Christian faith), but was still very much a time of
apologetics proper (the defense of the Christian faith). If the faith
was being marred from within, by poor doctrine and abusive
leadership, the true teaching needed to be defended.
Internal purification of the Church: The debate regarding
indulgences, the Mass, Saints, purgatory, the sufficiency of
Scripture, and the Pope.
From Renee Descartes on Christian philosophers grappled with
apologetics in light of theories of knowledge.
Deism and Atheism: External emphasis.
15th – 16th Cent.:
Martin Luther
(1483-1546 ad)
Thought of reason outside of faith
as helpful for this earthly
environment, but when an
unbeliever applies reason to faith
reason becomes, “the devil’s
whore.” Yet, once one submits to
revelation, reason can expand
upon theology.
Philipp Melanchthon – was one
of Luther’s disciples, who initially
accepted the above idea, but later
embraced apologetics as valuable
in dealing with the unregenerate.
16th Cent.:
John Calvin
(1509-1564 ad)
Reason can assist man in
knowing certain things about
God, but without God’s electing
power, man will fall into idolatry.
He does argue for the truth of
Scripture, but these facts only
serve (in his thinking) to confirm
to a man what the Holy Spirit has
already demonstrated.
17th Cent.:
Rene Descartes
(1596-1650 ad)
Attempted to argue from the most
basic knowledge one can have “I
think therefore I am,” to the
reality of the external world and
then to God.
This stands opposite the
medieval apologists who
believed in starting from the
axiom that the external world
DOES exist, and then arguing for
God’s existence from there.
17th Cent.:
Hugo Grotius
(1583-1645 ad)
Works: The Truth of the Christian
Religion, is a popular work of
apologetics which contains
responses to Islam and Judaism,
as well as endorses the use of
arguments for God’s existence.
Credited with having written the
first popular level apologetics
book in history.
17th Cent.:
Blaise Pascal
(1623-1662 ad)
Works: The Pensees, which is
incomplete. It is most famous for
the “Wager” argument.
Though incomplete, the work
contains many evidential
thoughts.
Nevertheless, Pascal was most
focused on the personal and
relational aspects of Christianity.
17th-18th Cent.:
John Locke
(1632-1704 ad)
Works: The Reasonableness of
Christianity as Delivered in the
Scriptures.
Focuses on arguments against
deism which had become very
popular in his day.
Also gives arguments for the
existence of God, based on
causality.
Believed in the verbal inspiration of
Scripture.
17th-18th Cent.:
Samuel Clarke
(1675-1729 ad)
Works: The Unchangeable
Obligations of Natural Religion and
the Truth and Certainty of the
Christian Religion.
Responded to skeptics of his time
asserting that through natural
theology one can know that there
is a God and much about His
nature.
Argued that a deist who honestly
considers the Christian faith will
embrace it. If he rejects it he will
inevitably become and atheist.
18th Cent.:
Joseph Butler
(1692-1752 ad)
Works: The Analogy of Religion,
Natural and Revealed, to the
Constitution and Course of Nature.
Assumes God’s existence since he’s
arguing primarily with deists.
Butler argues that from our
experiences and knowledge of morality
we should be able to recognize by
analogy that this life is a probationary
period before a new world. Thus, moral
improvement is the goal of life.
He does further argue from natural
religion.
18th Cent.:
Thomas Reid
(1710-1796 ad)
Works: Inquiry into the Human
Mind.
He came to be known as a
Scottish Common Sense Realist.
He felt that analytic philosophy
(ala Descartes) had gone so far
into the obscure as to be
useless.
This view, he thought, would
place Christian apologetics back
where it should be.
18th- 19th Cent.:
William Paley
(1743-1805 ad)
Works: A View of the Evidences
of Christianity and Natural
Theology.
Paley responds to Hume on
miracles.
Lays out the best evidence of his
predecessors.
In Natural Theology he gives a
great defense of the argument
from design.
The
19th Century An Alternative to
Typical
Apologetics
Reasons to Defend
Because of developments during the 18th century, the
19th century apologists had the tools and resources for
a variety of approaches. What began among the most
prominent names, however, was a move away from
the medieval theistic proofs and toward an
understanding that unbelievers will not be convinced
by evidence. This would ultimately lead to be
influential in fideistic views on the one hand and the
development of presuppositional apologetics on the
other.
18th-19th Cent.:
Immanuel Kant
(1724-1804 ad)
Works: Critique of Pure Reason, and
Religion within the limits of reason
alone.
Attempted to synthesize empiricism
and rationalism.
Argued for embracing God’s existence
because of subjective and individual
moral experience.
Rejected attempts argue for God from
reason. Specifically rejected the
Teleological, Cosmological, and
Ontological arguments.
19th Cent.:
Soren Kierkegaard
(1813-1855 ad)
Works: Philosophical Fragments
Like Kant, rejects any attempt at
rational attempts to demonstrate
the existence of God.
Like Gutthold Lessing, rejects any
attempt to demonstrate the truth of
Christianity by means of historical
evidence.
Kierkegaard is, therefore, a true
fideist. One must simply believe in
Christianity.
19th Cent.:
Alexander B. Bruce
(1831-1899 ad)
Wrote: Apologetics; or
Christianity Defensively Stated.
According to Avery Dulles, Bruce
is the true progenitor of
presuppositional apologetics.
His view is that the arguments
will be completely unsuccessful
in convincing the unregenerate
man.
The
20th – 21st
Century
The First Century
All Over Again
Reasons to Defend
The 20th and 21st centuries have seen a flourishing of
apologetic methods, and opponents. Classical
apologetics has been bolstered, presuppositional
apologetics has been further developed by men like
Van Til. Evidential apologetics has continued.
Cummulative case apologetics has become a popular
approach and Reformed Epistemology has been
created (or at least formalized).
19th- 20th Cent.:
Abraham Kuyper
(1837-1920 ad)
Works: Principles of Sacred
Theology
Believed that there was no
common ground between believers
and unbelievers.
"Oh, no single piece of our mental
world is to be hermetically sealed
off from the rest, and there is not a
square inch in the whole domain of
our human existence over which
Christ, who is Sovereign over all,
does not cry: 'Mine!'"
19th- 20th Cent.:
B. B. Warfield
(1851-1921 ad)
Works: no specifically
apologetics books, but had a
strong apologetic emphasis in
most of his work.
Departed from some of his
reformed contemporaries in their
views of presuppositionalism
over Classical apologetics.
Argued for a two step method.
20th Cent.:
C.S. Lewis
(1898-1963 ad)
Works: Mere Christianity;

argument and offered the
Trilemma argument in favor of
Jesus’ divinity.
20th Cent.:
Cornelius Van Til
(1895-1987 ad)
Works: The Defense of the
Faith.
Popularized Presuppositional
apologetics.

principles in order to argue
against Christian beliefs.
This has spawned the rise of
transcendental arguments.
