Unknown James

Some view the Epistle of James as pseudonymous.  This author introduces himself merely as “a servant of God and of the Lord Jesus Christ” without invoking any special family relationship to Jesus or even mentioning Jesus widely in this letter.  Secondly, the cultured Greek language of this epistle and its many unique NT Greek words, could not have been written by a Jerusalem Jew.  Some scholars argue for a primitive version of the letter composed by someone called James and then later polished by another writer.  There are some parallels with other Christian literature of the early second century, so that this epistle seems to reflect the socio-economic situation of Christians in the late 1st or early 2nd century.  It could have been written by any Jewish Christian in the Roman Empire who spoke and wrote Greek fluently.  Nevertheless, this epistle of James is an accepted part of the canon the New Testament.  Do you know any anonymous authors?
