A letter to America

I had an idea the other day to write a book that was modeled something like Paul's letters to the Corinthians and address it to America.  It's not a bad idea really but I'm not sure I could really pull it off.  I began to think about all the issues American culture and life bring to the table and I began to think about the volumes of work a letter like this would require. Paul's letter was addressed to the church in Corinth and unfortunately there isn't really a church of America, in fact if we just counted the catholic and protestant churches we could write over 300 letters to just the denominations that exist in America; quite a task to say the least. So where to start, if Paul were to address a letter to the church in America, where would he start, what would he see as the main issues?

Please send me your feedback, I would love to hear what you think Paul would say to us.
