Topics: Who are John and Edward Grimes?
Robert Kysar writes the following on the authorship of the Gospel of John ( The Anchor Bible Dictionary , v. 3, pp. 919-920):
If the author of the Gospel of John were an eyewitness, presumably the author would have known that Jesus and his compatriots were permitted to enter the synagogues. But at one several points it is stated that those who acknowledged Jesus as the Christ during the life of Jesus were put out of the synagogue. This anachronism is inconceivable as the product of an eyewitness.
Kysar states that most scholars today see the historical setting of the Gospel of John in the expulsion of the community from the synagogue (op. cit., p. 918). The word aposynagogos is found three times in the gospel (9:22, 12:42, 16:2). The high claims made for Jesus and the response to them (5:18), the polemic against "the Jews" (9:18, 10:31, 18:12, 19:12), and the assertion of a superiority of Christian revelation to the Hebrew (1:18, 6:49-50, 8:58) show that "the Johannine community stood in opposition to the synagogue from which it had been expelled." (p. 918)
