Hi Terry,
I just finished listening to Zealot, by Reza Aslan. He comments on this passage as well.
His take on Paul's ministry was that James, who was Jesus' brother, had a huge problem with Paul for taking Jesus' teachings to the Gentiles. James was the head of the Jesus Movement in Jerusalem, and as the brother of Jesus, was in a far better position than Paul to know what Jesus' thoughts on matters would have been. Bottom line, though, was that Jesus was a Jew, and his message was intended for the 'lost sheep of the house of Israel', not the Gentiles. James considered Paul to be an APOSTATE, and subjected him to the humiliation of shaving his head in a Nazirite ritual in the temple (Acts 21:20-25).
As a matter of fact, he claims that 2 John is also referring to Paul, when describing the antichrist, because Paul was preaching a message that appealed to Hellenistic sensibilities over the Jews, who were the actual intended recipients of Jesus' gospel.
7 many deceivers have gone forth into the world, persons not confessing Jesus Christ as coming in the flesh. This is the deceiver and the antichrist.
8 Look out for yourselves, that YOU do not lose the things we have worked to produce, but that YOU may obtain a full reward. 9 Everyone that pushes ahead and does not remain in the teaching of the Christ does not have God. He that does remain in this teaching is the one that has both the Father and the Son. 10 If anyone comes to YOU and does not bring this teaching, never receive him into YOUR homes or say a greeting to him. 11 For he that says a greeting to him is a sharer in his wicked works. ~ 2 John 7-11
So here, John was actually instructing Christians of Jewish origin to shun Paul and anyone following him, considering Pauline Christians to be "deceivers" and of the "antichrist".
All I could think when I heard this was "WWWWOOOOOOOoooowwww"
