Philippians is an epistle. The word epistle comes from the Greek word epistole that means “letter” or “message.” Epistles were a primary form of written communication in the ancient world, especially during New Testament times. Since many of the New Testament books were originally written as letters to churches or individuals, they are referred to as the Epistles.
It is evident that Paul wrote the letter from prison in most likely Rome
Paul’s primary purpose in writing this letter was to thank the Philippians for the gift they had sent him upon learning of his detention in Rome. However, he makes use of this occasion to fulfill several other desires: to report on his own circumstances to encourage the Philippians to stand firm in the face of persecution and rejoice regardless of circumstances to encourage them to humility and unity to commend Timothy and to warn the Philippians against false teachers. As we’ll see in Chapter 3.
