When asked "who are you?" one may answer by your name, your role, or give a blank stare pondering why they are inquiring of your identity. The primary answer is influenced by the context in which the question is being asked. If you were living in the SW coast of Asia 2000 years ago - modern day Turkey - you may have answered if you were a Jew or a Gentile, an apostle, a prophet, maybe even a magician. Paul's letter to the Ephesians addresses identity in the community and most important, in Christ.
