To be American is to bring obvious differences together to be integral parts of a unifying body, and to remove the power of those differences to bring harm to the nation as a whole.
1 Corinthians 12:12-14 NIV
 Just as a body, though one, has many parts, but all its many parts form one body, so it is with Christ.  For we were all baptized by one Spirit so as to form one body---whether Jews or Gentiles, slave or free---and we were all given the one Spirit to drink.  Even so the body is not made up of one part but of many.
When this nation was formed, there was a great diversity of population occupying the land. There were people from many nations and those who were slaves, along with the free. Business owners, servants, male, female, strong and weak all were living in the areas designated to be states. Rather than being deterred by their differences, those people came together, just as they were, to form first states, and then a single and unified nation. There would be a great deal of progress made towards enabling each citizen of a differing identity to flourish and be free to develop their unique gifts. Though there still is, and will ever be, a need for continued progress, the purpose will also continue to be the forming of one nation. To be American is to bring obvious differences together to be integral parts of a unifying body, and to remove the power of those differences to bring harm to the nation as a whole.
For all those who actually drink of the same Spirit, there is participation in the forming of a single body. No matter how other labels may have identified and separated up to that point, the purpose for every differing characteristic is now the forming of Christ’s body. Where there might be reason to be offended, judge, and become isolated due to a great variety of differences, drinking of the Spirit will always bring down those barriers and establish a single heart and purpose of love and unity. Who you are, where you’re from, and your personal preferences give way to letting that be part of the Spirit’s forming.
