I will require them to purchase at least one commentary. They will be able to choose from Fee, Malherbe or Wannamaker. They will also have a selection or articles and essays to read. But I am unsure of what to adopt as the primary textbook. I am considering DonFried's Paul Thessalonica and Early Christianity, but have not made a final decision.
Are there any suggestions from others? Are you aware of or have used a particular book that will give good introductory coverage of these two letters? I would be happy to hear your suggestions for either a textbook or any readings that you think would be helpful.
