Priority: Mark or Matthew
I promised I would get back to this thread concerning whether Matthew or Mark were written first.
At first I was going to reference R. T. France in his NICNT-Matthew commentary. This is a c.1200 page reference on Matthew with a big introductory section. As it turns out, though, France wrote extensively about this isssue in another book that he authors (Matthew: Evangelist, pp.24-46), one which I don't have in my library, and he only gives some basic information about the subject in the NICNT book.
Nevertheless, what he does say agrees in substance with the NAC-Matthew commentary and the Bible Knowledge Commentary. So what I will share below is three paragraphs from the Bible Knowledge Commentary (Vol II, NT, p.96-97, which lays out the general pros and cons to the subject of which (Matthew or Mark) was likely written first.
[Start of quote.]
Many scholars believe that Mark was the first Gospel written and that Matthew and Luke used it as a primary source document along with material from other sources. Luke, in fact, stated that he used other documents (Luke 1:1-4) Several arguments support the priority of Mark:
(1) Matthew incorporates about 90 percent of Mark, and Luke over 40 percent - over 600 of Mark's 661 verses are found in Matthew and Luke combined.
(2) Matthew and Luke usually follows Mark's order of events in Jesus' life, and where either of them differs for topical reasons the other always holds to Mark's order.
(3) Matthew and Luke hardly ever agree against the content of Mark in passages where they all deal with the same subject.
(4) Matthew and Luke often repeat Mark's exact words but where they differ in wording, the language of one or the other is simply grammatically or stylistically smoother than Mark's (cf., e.g., Mark 2:7 with Luke 5:21).
(5) Matthew and Luke seem to alter Mark's wording in some instances to clarify his meaning (cf. Mark 2:15 with Luke 5:29) or to "tone down" some of his strong statements (cf., e.g., Mark 4:38b with Matt. 8:25; Luke 8:24).
(6) Matthew and Luke sometimes omit words and phrases from Mark's "full" descriptions to make room for additional material (cf., e.g., Mark 1:29 with matt. 8:14; Luke 4:38).
Five major objections have been raised against the theory of Marcan priority:
(1) Matthew and Luke agree with each other against the content of Mark in some passages dealing with the same subject.
(2) Luke omits all reference to the material in Mark 6:45-8:26 which is unusual if he used Mark.
(3) Mark occasionally has bits of information not found in the same incident reported in Matthew and Luke (cf. Mark 14:72).
(4) The early chuch fathers apparently believed in the priority of Matthew instead of Mark.
(5) Marcan priority practically requires the view that Matthew and/or Luke were written after the destruction of Jerusalem in A.D. 70.
In response to the first objection, the agreements of Luke and Matthew against Mark involve a very small number of passages (ca. 6%) and are probably due to common sources (i.e, oral tradition) which they used in addition to Mark.
The second objection falters on the commonly acknowledged fact that the Gospel writers selected material from their sources in line with their purposes. Luke may have omitted reference material in Mark 6:45-8:26 in order not to interrupt the development of his own journey-to-Jerusalem theme (cf. Luke 9:51).
This also answers the third objection in addition to the fact that mark had Peter as an eyewitness source.
The fourth objection stems from the arrangement of the Gospels in the New Testament canon. To infer from this that the early fathers believed Matthew was written first is not valid. They were concerned about the apostolic authority and apologetic value of the Synoptic Gospels, not their historical interrelationships. Thus Matthew, written by an apostle and beginning with a genealogythat linked it nicely to the Old Testament, was given first place. Furthermore, if Matthew were the first Gospel written and it were used by Mark and Luke, one would expect to find places were Luke follows Matthew's order of events and Mark does not - but this does not occur. It is also more difficult to explain why Mark would shift from Matthew's order than vice versa. displacement of order favors Marcan priority.
In response to the fifth objection, Marcan priority does not necessitate dating Matthew and/or Luke after A.D. 70 (cf. comments on "Date").
[End of quote. Note that paragraphs were broken up to highlight the major pro/con arguments. The material was originally in three paragraphs. Italics is preserved from the reference.]
Personally, the arguments presented here are very compelling, and even-handed, to me. When compared with the WT All Scripture publication, the arguments there are very simplistic or surface level. As if the writers did not expect the reader to be able to comprehend much beyond a surface explanation.
