Paul's letter to the church at Philippi is a moving insight into early Christianity. No letter displays Paul's fondness for a church as much as Philippians, and this passion is accompanied by a profound sense of thanksgiving for the church and its generosity. But in Philippi Paul also faced opponents, and the interpretation of the letter requires that the reader understand something about these people whose vision of Jesus was other than Paul's. The short letter to Philemon tells the story of a Christian slave named Onesimus. Paul appeals on Onesimus's behalf and argues for Christian treatment of one another.
Together, these two letters show much of Paul's vital passion for the church and the bonds that held early Christians together in their faith.
