Searcher,
You have to understand the overall tone of the letter of Paul to the Galatians. Paul was making his defense that his apostleship was in no way inferior to that of the original twelve apostles. It is rather clear that there was a sentiment in the congregations that the original twelve, being Jews that walked with Jesus during his eartlhy ministry, were more "genuine" apostles, whereas Paul was appointed in a supernatural way that many (possibly including some of the original apostles) looked down on it. It took years before the other twelve regarded Paul as one of their "peers". Paul obviously felt some disgrunt about that.
Especially where congregations with many Jews existed had a tendency to resist the apostolic authority of Paul - no doubt because Paul was radical in the rejection of the Jewish habits - while some of the apostles, namely James and the "older men" of the congregation of Jerusalem, were in favor of a form of Christianity closer to judaism. Hence the letter that Paul wrote to the Hebrews.
I disagree that Paul had a revelation regarding the rejection of circumcision; He simply understood it with the help of the Holy Spirit. Notice that Peter was among those who issued the letter from the "apostles and older men" in Jerusalem that stated that circumcision wasn't a requirement for Christians. He clearly felt that was the direction of the Holy Spirit.
The episode reported by Paul in Antioch hasn't got to do with circumcision or resistence to the Holy Spirit. It has to do with a personal weakness of Peter, who sometimes gave in to fear of men - remember the episode where he denied Christ three times for the same fear of men. He wasn't perfect. Yet, Christ loved him and chose him.
Also, you equate the amount of letters written with amount of "spiritual food" produced. If that was the measure, then Jesus wouldn't have produced ANY spiritual food, for he has not written anything. That's not a fair acessment.
Finally, regarding the use of "a slave" versus "the slave", I looked it up in the original Greek before i wrote the article. It's the definite article used, therefore "the slave".
