The differences between John and the Synoptics provide an opportunity for scholars to study the formation of a gospel from a different angle. John may have used other Gospels, or purposefully ignored them. Often complicated scenarios are created in order to describe multiple versions of the Gospel of John. Raymond Brown suggested a plausible multiple edition theory to explain how John’s gospel developed over a period of time. In most “multiple editions” theories there was a single base document which underwent several revisions, possibly at the hand of the original author, over a number of years.
Brown’s first stage was the actual public ministry of Jesus and his disciples. After the resurrection, the twelve apostles publicly preached the resurrection of Jesus. The synoptic gospels reflect this apostolic preaching. The tradition that Mark preserve the preaching of Peter may indicate that the outline and content of the book as the content to of the apostolic “trust.” Matthew and Luke make use of Mark, and possible Q (or Matthew has the Q material, either way, Matthew and Luke reflect the Galilean disciples of Jesus).
According to Brown, John reflects the preaching and teaching of the disciples of Jesus in and around Jerusalem. This accounts for the different sorts of information that was remembered and passed along, for differences in tone and language, for the emphasis on Jerusalem and the Jewish festivals, and possible (so says Brown), the Light / Dark theme that is parallel to what we read in the Qumran materials.
It is possible that the Johannine Community included Samaritans, based on John 4 and 8:48 (Jesus is accused of being a Samaritan.) Jews and Samaritans sharing fellowship in a single religious community would have been scandalous, especially in pre-70 Judea. Brown suggests that Jews that accepted Jesus as the Messiah convinced in synagogues.
But relationships between these Jews and Samaritans would have been tense. Discussion of Jesus as Messiah generated a number of “homilies” preserving Jesus’ teaching as attempts to convince Jews he was the Messiah. It is possible that some time before A. D. 70 these Jewish Christians were expelled from the synagogue, ostracized and persecuted (as implied in John 1:11, 10:28-29; 15:18, 16:2 and the “not of this world” theme in 15:18, 16:3, 16:33).
The Gospel of John therefore could be aimed at Jewish Christians that are still in the synagogue (“crypto-Christians” in Brown) who are not fully “Christian” in the opinion of the author. They need to come out and be separate from the Synagogue. A second aim would therefore be to continue to try and convince Jews and Jesus was the Messiah.
Brown’s work is well-respected and is always discussed in recent study of the Gospel of John, but it does not appear this scenario has convinced everyone, as Paul Rainbow comments in his recent introduction to Johannine Theology, scholars “amass tomes trying to squeeze theories from the almost dearth of information that we have about unknown authors and redactors” (53).
Nevertheless, there is something to Brown’s contention that the Gospel of John is a kind of reflection of the “parting of the ways” between Judaism and Christianity in the last third of the first century. This accounts for the Jewishness of John’s Gospel while also reflecting a fairly well-developed Christology. If this Gospel is some kind of a Jewish-Christian missionary tract, how would our reading of John change?
Are there specific elements in John that are more “Jewish” than often assumed?
