It’s helpful to imagine Paul in a prison cell as he writes the book of Ephesians, particularly chapter 4. To be imprisoned is to be divided off from humanity. So, Paul speaks about unity and provides a vision of what brings us together. He says that God considers us all to be one and that when we accept the Christian faith we all have the same baptism, even though some are sprinkled as infants and others dunked under the cold, muddy, waters of the Penobscot River. We are one, in spite of whatever wind of doctrine fills our sails. We are one, no matter what work fills our days, or what economic fortunes have befallen us.
