Michael Gorman, a New Testament scholar whose work I have found to be both insightful and refreshing, has recently published a fictional letter from the Apostle Paul to Christians in the United States in the Christian Century.  I heard Gorman present an earlier version of this letter during an address at a theological conference at Northeastern University in Rochester, NY, a couple of years ago, which was subsequently published in the Canadian Theological Review.  It is well worth the read.  I will be incorporating it into my upcoming Christian Ethics course.  You can access it here.
