Read: Philippians 1:1-2
Paul and Timothy, servants of Christ Jesus, to all God’s holy people in Christ Jesus at Philippi… Phil 1:1a
The ancient practice of correspondence had one very distinct advantage over our modern method. They signed their name at the beginning of the letter. Have you ever received a letter, perhaps two or three pages long, and had to flip through the pages to see the name at the end before you knew who the letter was from? The ancients were much more efficient, putting their name at the beginning.
The address of the letter is very distinctive: to the saints in Christ at Philippi. In Christ was the source of their lives. In Philippi was the sphere in which they lived it. Both are very important in this letter. For what these people would be as citizens in Philippi would be determined by who they were as Christians — in Christ.
