Judgerightly,
Do you really think that the words from James can be discarded by us, now that it has been made available to us?
Did I say that they should be discarded? No, I did not.
All Scripture is given by inspiration of God, and is profitable for doctrine, for reproof, for correction, for instruction in righteousness,that the man of God may be complete, thoroughly equipped for every good work. - 2 Timothy 3:16-17 http://www.biblegateway.com/passage/?search=2Timothy3:16-17&version=NKJV
The problem is that you're trying to read someone else's mail and respond as if you were them, instead of reading it and understanding it was written to someone else, and responding as such.
Do you really think that James taught differently than Paul?
Yup.
Tell me the differences between James and Paul.
James, one of the twelve Apostles, and the brother of Christ, who was given his doctrine by Jesus while he was still on this earth, preached to the twelve tribes of Israel, scattered abroad, the Jews.
Paul, formerly Saul of Tarsus, who was given his doctrine by Jesus after He had ascended into heaven, preached "a mystery" to the Jews and the gentiles, but, as you surprisingly quoted above, in Galatians 2:7-9, came to the agreement with the other twelve that they should go to the Jews only, and he only to the gentiles.
James taught the Law to his audience, and Paul taught Grace to his audience.
