Since I haven't written anything here for a VERY long time and I'm taking a break from classes and I thought I'd share a couple essays I wrote for my previous classes. This first one is a research paper I submitted for my History of Christianity class a while back.
Introduction
The
 apologetic arguments of the early and medieval church fathers are still
 useful today. This short paper will discuss some of the history of the 
early and medieval church fathers as apologists and some of their major 
arguments and how modern apologists can use those arguments still today.
 This paper will go through Justin Martyr, Augustine, Anselm, and Thomas
 Aquinas; concentrating on these writings: Martyr’s First and Second 
Apology, Augustine’s 
Confessions, Anselm’s 
Monologium, and Aquinas’ 
Summa Theologica. In these works, some arguments are no longer used, 
some are still in use, and some should be revived. This paper will 
attempt to show that there are various arguments and styles that 
historical apologists used that have fallen out of style but should be 
revived. Some of these are specific arguments and some are styles. 
Modern apologists are removed from the Church Fathers not only in time 
but in desires, thoughts, attitudes, and arguments. These trends are 
some things that should be changed in modern apologetics.
Justin Martyr
As
 is appropriate this paper will open with the oldest of the Church 
Fathers that is well known for his apologetics, Justin Martyr (c. 
100-165).1 Justin studied Greek philosophy including stoicism, 
Aristotelian philosophy, Pythagorean philosophy, and Platonism before 
becoming a Christian.2 However, as Lane says, “[Justin] was not just a 
Christian seeking to relate Christianity to Greek philosophy. He was a 
Greek who had come to see Christianity as the fulfillment of all that 
was best in philosophy, especially in Platonism.”3 This is reminiscent 
of a great quote from a modern Christian philosopher, William Hasker, as
 he writes in his short book on Metaphysics, “[I am] a Christian who 
loves philosophy and would like to consider himself a philosopher; [I 
am] a philosopher who loves Jesus Christ and wants to be known as a 
disciple. A Christian first, a philosopher second—but neither one at the
 expense of the other.”4 This modern quote seems to reflect the ideas of
 Justin Martyr. Justin himself clearly held a high view of philosophy 
and Greek philosophers. In his first Apology, he references philosophy 
quite often and even writes a chapter saying that Plato’s Timæus 
referenced the image of the cross from the Old Testament story of Moses 
and the serpent lifted up in the desert.5 How well this works as an 
argument is not so clear. However, Justin does write quite a bit in 
defense of Christians that were being unfairly mistreated. Justin 
countered ideas like how Christians were called atheists, and he argues 
that Christianity is the true philosophy.6 One of the key points that 
can be clearly seen in Justin’s “short” works (the first and second 
Apologies) is his extensive use of non-Christian writings and thoughts. 
He is not afraid to reference various Greek writings. If anything, he 
seems to like co-opting Greek philosophers in his writing. It seems that 
most modern apologetics works use Greek terminology, but do not often 
reference Greek or other non-Christian writing to co-opt them into their
 writings. Modern apologists could do well to use the philosophy of 
non-Christian writers against them. Christianity does have the most 
consistent philosophy and modern apologetics writers would do well to 
emphasize that and demonstrate it using both biblical arguments and 
non-Christian philosophy.
Augustine
Augustine
 (Bishop of Hippo) lived about 189 years after Justin had died 
(354-430)
7 and is probably one of the most famous of the Early Church 
Fathers to this day.
8 Augustine studied Neo-Platonism and became a 
Christian after following Manicheism for a time and was a prolific 
writer over a wide range of subjects.
9 His most famous work, 
Confessions, is a somewhat dense autobiographical work that starts with 
his childhood in book one and progressing through his life and 
confessions/theology to book thirteen.
10 Like Justin, Augustine seemed 
happy to incorporate certain (Greek) philosophical ideas into his own. 
And, he wrote of his struggles using Neo-Platonic thoughts and 
terminology.
11 These influences may or may not have been a good thing, 
but Augustine and others that were influenced by Greek philosophy still 
seem devoted to building their theology on the Bible. Augustine’s 
apologetic writing is as varied as his theological works are, but his 
famous line, “Thou madest us for Thyself, and our heart is restless, 
until it repose in Thee”
12 is an early version of C. S. Lewis’ argument 
from desire. “If I find in myself a desire which no experience in this 
world can satisfy, the most probable explanation is that I was made for 
another world.”
13 Also, Augustine’s view that evil is “nothing but a 
privation of good,” is a kind of answer to the “problem of evil.”
14 
Augustine also referenced Romans 1 as a kind of cosmological argument.
15
 The lessons of Augustine are less in the form of what he writes about, 
rather in how he writes. Augustine’s writings are very personal in 
nature. Augustine also quotes the Bible very often. Many modern 
apologetics texts tend to not reference the Bible hardly at all. So, 
modern apologetics writers ought to follow Augustine’s example in how he
 writes from personal experience and how he utilizes biblical arguments 
throughout his work.
Anselm
Anselm
 has somewhat of a bad reputation among many apologists today as he was 
one of the first, and certainly the most famous for using, the 
“ontological argument.” Anselm lived in the early 11th century (c. 
1033-1109) and wrote creatively as the Bishop of Canterbury.
16 As 
mentioned above his most famous argument comes in the form of the 
ontological argument. The argument, found in the 
Monologion:
[A]ll
 other goods are good through another being than that which they 
themselves are, and this being alone is good through itself. Hence, this
 alone is supremely good, which is alone good through itself. For it is 
supreme, in that it so surpasses other beings, that it is neither 
equalled nor excelled. But that which is supremely good is also 
supremely great. There is, therefore, some one being which is supremely 
good, and supremely great, that is, the highest of all existing 
beings.17
This argument has been reworded, 
reformatted, and argued by multiple writers since Anselm penned it. The 
Internet Encyclopedia of Philosophy lists such writers as “St. 
Bonaventure, St. Thomas Aquinas, Descartes, Gassendi, Spinoza, 
Malebranche, Locke, Leibniz, Kant, Hegel, … Charles Hartshorne, Etienne 
Gilson, Maurice Blondel, Martin Heidegger, Karl Barth, Norman Malcolm, 
and Alvin Plantinga.”
18 Unfortunately, though that is an impressive list
 of writers, it is not considered a very good argument by many 
apologists today. Many think of the ontological argument as defining God
 into existence. And, though that is a fair critique, others, most notably 
Alvin Plantinga, have revived the argument with some success. The 
Stanford Encyclopedia of Philosophy (online) has an entire article 
devoted to this argument that often references Plantinga’s version.
19 It
 is the position of this paper that apologists have too long ignored 
this argument, which in its own way also reflects the ideas expressed in 
Romans 1. All people actually know intuitively that God exists and this 
argument can move other arguments into the realm of possibility. It can 
establish the idea that belief in God is reasonable, because after all 
it is possible that there is a “Best Being” (God), to use the term 
“good” that Anselm uses, and if it is possible that such a being exists,
 then it is at least reasonable that it be so. This argument can be used
 as a stepping stone. If one can get a skeptic to at least admit that it
 is possible for such a being to exist, then one can move on to 
other arguments like the cosmological arguments, which were very popular for the next apologist 
this paper will discuss.
Thomas Aquinas
Thomas
 Aquinas, who lived from 1224-1274, is well known for his use of Aristotelian philosophy.20 This may be a weakness of Aquinas because 
critics of Christianity often say that it is unduly influenced by 
various Greek philosophers and there are even some Christians who 
disagree with the Greek influences and refuse to listen to anything 
written by such theologians because they deem them unbiblical in their 
reliance on Greek philosophy.21 Aquinas was so enamored with Aristotle 
that he took to simply calling him “the Philosopher.”22 Aristotle not 
only heavily influences Aquinas, but Aquinas heavily referenced the 
writings of Anselm and Augustine (though not always agreeing with 
them).23 He was and still is revered, particularly by Roman Catholics, 
as the best philosopher/theologian/apologist of his time, perhaps of all
 time.24 Undoubtedly, Aquinas’ most famous and influential apologetics 
work is in his “five ways.”25 The "first way:"
It
 is certain, and evident to our senses, that in the world some things 
are in motion. Now whatever is in motion is put in motion by another, 
for nothing can be in motion except it is in potentiality to that 
towards which it is in motion; whereas a thing moves inasmuch as it is 
in act. For motion is nothing else than the reduction of something from 
potentiality to actuality. … It is therefore impossible that in the same
 respect and in the same way a thing should be both mover and moved, 
i.e. that it should move itself. Therefore, whatever is in motion must 
be put in motion by another. If that by which it is put in motion be 
itself put in motion, then this also must needs be put in motion by 
another, and that by another again. But this cannot go on to infinity, 
because then there would be no first mover, and, consequently, no other 
mover; seeing that subsequent movers move only inasmuch as they are put 
in motion by the first mover; as the staff moves only because it is put 
in motion by the hand. Therefore it is necessary to arrive at a first 
mover, put in motion by no other; and this everyone understands to be 
God.26
This is just the "first way" and each of the 
other arguments are just as powerful. They each deal with different 
aspects of the universe, so they could be taken together as all 
cosmological arguments. The "second way" deals with efficient causes 
(again using Aristotelian terminology); the "third way" deals with the 
nature of being and not being; the "fourth way" deals with the gradation 
of goodness in everything (somewhat similar to Anselm’s ontological argument); and 
the "fifth way" is an argument from design.
27 What can one learn from 
Aquinas’ apologetics? Clearly, there is a ring of confidence in the way 
Aquinas writes. So, perhaps the best point to learn from Aquinas is his 
tone. He writes as one having authority, interestingly, as Jesus was 
described (Matt. 7:29 and Mark 1:22).
Lessons
The
 lessons we can learn from these great masters are too many and too 
powerful for this short paper to express. However, let us try to sum 
them up here. Justin Martyr has a few weaknesses. His weaknesses are not
 born out of his inabilities or anything like that; it is just that he 
was writing to a different audience in a different time period. In fact,
 when he was living/writing the canon had not even been established 
yet.
28 Justin’s weaknesses are that he appeals almost exclusively to the
 Scriptures to make arguments. But, this is also a strength. Modern 
apologists have been drawn to a style the reflects that of Aquinas, who 
relies more on philosophical argument to make apologetic points.  But,
Augustine is not without his weaknesses as well. He had an unfortunate 
emphasis on Church authority that Counter-Reformers latched on to, as 
well as a view of faith-leading-to-salvation that Reformers admired.
29 
Perhaps the best lesson in that is for modern apologists to be careful 
not to espouse overly contradictory views. Regardless, Augustine’s 
candor and self-reflection are things that modern apologetic writing 
would do well to emulate. When one comes to Anselm there is much to be 
said (indeed much has been said), but one of his weaknesses could be 
that his work is dense; it is nearly impenetrable. It takes scholarly 
work well beyond the scope of this short paper to truly understand even 
small parts of this master’s work. Despite being opaque with difficult 
phrasing Anselm certainly has a powerful apologetic tool in the 
ontological argument. Modern apologists should follow Plantinga as he 
follows Anselm in pushing this argument as a starting point. Lastly, 
this paper explored some of Thomas Aquinas’ work and it is certainly 
tough to find a weakness here. Perhaps the only one, as has already been
 mentioned, is Aquinas’ near infatuation with Aristotle. Aquinas’ style 
of authority is certainly to be respected and emulated, but there is a 
danger in speaking too authoritatively as well. That style can push away
 people seeking God. Yes, as previously mentioned, Aquinas’ strength is 
his confidence, but that strength can be a liability. It can push people
 away.
Conclusion
This
 paper is too short to contain all that is needed to really make the 
point expressed in the introduction. However, it should be clear that 
these four and many other major Christian Church 
thinkers/apologists/theologians of the past should still be studied 
today. There is much we can still learn from these masters. That is 
indeed why they are often referred to as “masters.” This paper on Justin
 Martyr, Augustine, Anselm, and Thomas Aquinas is just the tip of the 
iceberg concerning Church history with regards to apologetics. It is 
great thinkers like these that should encourage all of us to do our 
research and learn from these masters as they have learned from 
the Master
