This is the term applied to the study of the use of written sources by the evangelists. It is the earliest form of criticism, and has
been applied particularly to the relationship of the Synoptic Gospels to each other. It was J Griesbach who first placed the
Synoptic Gospels into three columns side by side with each other, drawing attention to both the striking similarities and striking
differences between them. That a relationship existed seemed clear. What that relationship was, was less obvious.
A Common Source for all 3 Gospels
Lessing suggested that a common written source could account for the obvious similarities of content and order found in
the 3 gospels. He suggested that this common written source had now been lost.
Other scholars suggested that the similarities were due to the gospel writers drawing on the same oral tradition, oral
transmission being the commonest form of passing on important material within the Jewish tradition.
However, what of the differences of content, wording and order within the accounts? To mention but one point, Mark omits
substantial amounts of Matthaen and Lucan material - and why do this if he was drawing on the same tradition?
Such easily identifiable weaknesses with the 'one common written source' theory led to scholars considering the
possibility that the Gospels relied on each other in some way. We'll consider these next.
Griesbach argued that as Matthew's Gospel was written by an apostle, he would not have used a non-apostolic source
(such as Luke or Mark). Matthew must therefore have been written first. Griesbach thought that there was evidence that
Mark had used both Matthew and Luke, and therefore put the 'reliance' as follows: Matthew was written first, Luke used
Matthew and Mark used both Matthew AND Luke. It was also felt that Matthew's 'Jewish' Gospel would have been written
earlier than one for Gentiles, as the early church was predominantly composed of Jewish converts.
This theory (although not is its original form has been taken up in recent years by Chapman and Butler, and by W Farmer.
Ancient tradition had held that Matthew the Apostle had recorded 'logia' (sayings) of Jesus, which he had then compiled
into a collection. Carsten Thiedde has suggested that Matthew's job as a customs official would have necessitated his
having a knowledge of shorthand, and that it is therefore possible that a record could have been made of Jesus' words as
he spoke.
Butler suggested that Mt wrote his gospel in Aramaic, which was used by Peter for preaching. Mark then transcribed
Peter's teaching, adding eye-witness embellishments. As evidence, he pointed to parts of Mark where a previous
knowledge of Matthew is implied.
The Two Source Theory
In the 19th century, scholars began to examine the evidence for Mark's gospel being written first. They noted substantial
parts of Mark being reproduced or paralleled in Matthew (about 90%) and about half of Mark appears in Luke's Gospel. So
only about 5% of Mark is unique to him.
There is evidence, too, of editting. For instance, in the healing of the epileptic boy (Mk 9) the Matthaen parallel seems to
have been substantially shortened. Yet this gospel is longer. If Mark is the later gospel, Why should the evangelist have
lengthened individual pericopae, but omitted large chunks of, say, Matthew, including important teaching material in Chs
5-7, including the Lord's Prayer?
The literary style of Mark's gospel appears less polished than that of Matthew and Luke, with more Aramaic words. These
two points were both taken as indicators that (a) Matthew and Luke had improved upon Mark's written style (although
many recent scholars have taken the literary devices of Mark much more seriously) (b) that Mark had either an
Aramaic-speaking audience (unlikely) or an Aramaic source, which is always viewed as a sign of an early source.
Where Matthew, Luke and Mark have parallel material, the order of events is often the same, and when, say Matthew,
departs from Mark's order, Luke agrees with it (and vice versa). Where there is no Marcan parallel, they differ. (e.g. the
Birth and Infancy Narratives.) This suggests that they may both have used Mark.
Christology
Luke and Matthew appear to have avoided or modified those verses in Mark which appear to place Jesus in a 'bad light'.
For instance, his family thinking he was mad. Luke omits the Marcan observation that lack of faith in Nazareth meant that
Jesus could 'do no mighty work there.' Another example of the difference between gospels is apparent when Matthew,
changes Mark's title 'Rabbi' (teacher) to 'Kyrie' (Lord).
Q
Matthew and Luke have parallel material that is not found in Mark. Much of this is teaching material - parables and
sayings, such as the Beatitudes, the Lord's Prayer and the parable of the Great Feast. This suggested to scholars that
they may have used another written source, probably independently of each other. This 'source' (if it existed) was named
'Q', after the German for Quelle. Q was assumed to be a written source, as many scholars did not believe that Matthew
and Luke used each other, yet the common 'Q' passages often show a remarkable similarity in wording and order. (Note
the word 'often'! - some scholars 'Q' might have been a mix of written material and oral tradition.)
So, we have the TWO Source theory. Matthew and Luke both appear to have used two sources - Mark and Q.
The Four-Source Theory
B H Streeter was the great exponent of this one. He accepted the evidence for the priority of Mark as above, and
explained the unique material in Luke and Matthew - such as the Birth Narratives, and the parables unique to both (eg The
Prodigal Son, Good Samaritan in Luke and the Wise and Foolish Virgins and Sheep and Goats in Matthew) by saying that
they each had an independent source. These sources are known (with stupendous originality) as 'M' and 'L'.
The arguments for the 4-source theory are strong - as I hope you can see. But there ARE flaws with it. And s the
4-Source theory is the foundation on which Redaction Criticism stands, you can see how the results of much modern
scholarship would be threatened if it were to fall.
Problems with the 4-Source Theory
- There are occasions when Matthew and Luke appear to agree with each other against Mark. This might be explained in
several ways - tradition, theology or perhaps Mark used Q- but differently. But it could also mean that one (probably Luke)
relied on the other as opposed to Mark.
- Why have Matthew, and especially Luke, left out parts of Mark? For instance, Luke contains no account of the Walking
on the Water. Perhaps he did not use Mark, or had an incomplete copy. However, in this case, I must say that the
tradition is so strong (it's in John too) suggests editorial redaction to me. And, as Russell point out, "most of the
omissions made by Matthew and Luke are not surprising".
- Did Q really exist? Why bother with it? For a start, there appears to be no trace of it elsewhere, although some scholars
claim to detect references in the Church Fathers. As an alternative, why not have Matthew use parts of Luke and vice
versa. Actually, most scholars are more prepared to consider Luke using Matthew, as there is much more of Matthew in
Luke than Luke in Matthew. But there are problems with this. If Luke were using Matthew, why does he leave out
additions that Matthew has made to Mark? And why is rather a lot of shared material, (like the Beatitudes, the Lost sheep
etc) used in a completely different context in Luke as compared to Matthew?
- The content of Q appeared to be 'unusual' to some scholars - a collection of sayings with the occasional summary verse
about miracles and the odd parable. However, there ARE christian documents that seem to consist largely of cooections
of sayings, such as the apocryphal Gospel of Thomas. Likewise, as we have mentioned, ancient tradition claimed that
Matthew the Apostle wrote down collections of 'logia' - sayings - and the Gospel of Matthew clearly consists of far more
than that!
Summary
In recent years, scholars have been prepared to acknowledge that the production of the Gospels was probably a much
more complicated process than had been previously though by Source, Form and Redaction Critics. The materials may
well have come from both oral and written sources. Luke, of course famously mentions several layers of material from
many sources - eyewitness, written, his own editing, in the prologue to his gospel Ch 1:vs1-4. That there is a relationship
between the Synoptic Gospels seems indubitable. At present most scholars accept the 4-source theory or something like
it. But it is more accepted that the ways in which the Early Church preserved and transmitted material were less
mechanical than had been previously thought, and there were probably intra- and inter-community ways of transmitting
written and oral material which were rather more sophisticated than early textual critics gave credit for. After all, it is clear
from the content - and the existence of Paul's letters to churches, that accurate transmission of material was early
considered important by Christians.
What IS important though, is that if the 4-source theory were to fall completely, then so would many of the findings of the
Redaction Critics, who depend on being able to compare use of parallel sources to draw conclusions from editorial use of
sources, about the theology, ecclesiology and christology of evangelists.
Briefly explain what it is and its relationship to the Synoptic Problem
Source Crit. claims to be able to identify different sources. Where material appears in more than one source (eg, Mk, Q,
Lk, John) many scholars are prepared to accept it as 'authentic' or 'reliable'. So the key elements of the Passion Narratives
appear in at least 3 different sources - Lk, Mk and Jn. Try to apply that to any passages specified in the exam question,
giving examples of parallell material, and if appropriate, of variations within the parallel. For example, all the gospels
describe Jesus going through trials before the Jewish and Roman authorities, and being found guilty, but there are striking
variations in what trials Jesus has.
Point out that Source Criticism is the foundation of Redaction Criticism, and show some of the conclusions that can be
drawn by the use of source and redaction Criticism. For example, in the trial narratives, Matthew closely'follows' Mark, but
has some deeply significant unique material in the exchange between Pilate's wife, Pilate and the Jews. What is the
significance of Matthew including this material? What might its inclusion only in Matthew suggest about the historical
reliability of the material?
Point out the significance for Redaction Critics if the 4-Source Theory were found to be in error.
