1) Despite the contention of some scholars, a distinction between anti-Semitism and anti-Judaism is helpful in understanding the message of the FG. The former may be defined as "the hatred and contempt for the Jewish people and their culture." The latter may be defined as "the prejudicial denial of the validity of the Jewish religion as a viable means of attaining genuine knowledge of God" (ie. eternal life).
2) Attempts to limit the referent of the noun Ioudaios ("Judeans," "Jewish authorities" etc.) fail to adequately interpret the FG. Furthermore, while there is a connection between the Evangelist's use of the nouns Ioudaios and kosmos, a purely symbolic meaning (Bultmann, Fortna) does not account for the fact that the Evangelist is referring to real personages. In sum, the noun Ioudaios has a number of referents (primarily religous leaders but also "crowds" of Jewish people) in the FG and describes historical individuals who interacted with Jesus. This reality unfortunately produces strong anti-Semitic potential.
3) The Evangelist's 'high Christology' presents serious problems for the continuing legitimacy of Judaism. While the noun "fulfillment" (versus "replacement") seems to best describe Jesus' relationship to Jewish religious institutions in the FG , its usage does not entirely free the FG from the charge of anti-Judaism. For example, to suggest that the FG portrays Jesus as the fulfillment of the temple (John 2:13-22) still requires one address the contuining role of the Jerusalem temple. In sum, one must ask, "If Jesus fulfills something, does he not (on a rather pragmatic level) also replace it?"
4) The historical situation that gave rise to the composition of the FG also has important bearing on this subject. Not only is the 'Johannine community hypothesis' historically problematic (see S. Motyer, R. Hakola), it leads to an unduly negative portrait of the relationship between the Evangelist's audience and the Jewish people. A better approach to the composition of the FG is to see it as a Christian response to the destruction of the Jerusalem temple in 70 AD (see S. Motyer, A. Kostenberger). This reading would (partly) see the FG as an evangelistic document (cf. 20:30-31) written to portray Jesus as the fulfillment of Jewish messianic hopes.
5) In summary, if one distinguishes between anti-Semitism and anti-Judaism, there is little room to justify labeling the FG anti-Semitic. After all, this Gospel portays Jesus as a Jew (4:22) and was written to (partly) present the Jewish people with the hope of eternal life. That said, the Evangelist's 'high Christology' and related 'replacement theme' make it difficult to avoid the label 'anti-Judaic.' That said, those who consider the FG authoritative should carefully consider Motyer's suggestion that "[a]nti-Judaism is consistent with a wholehearted love both for Judaism and for Jews" ("Editorial: Is John's Gospel Anti-Semitic?," Themelios 23 (1998): 1).
