The town of Philippi was a prosperous Roman colony named after King Philip II, father of Alexander the Great (Acts 16:12). The people of Philippi included many retired military and were proud of their Roman citizenship. Jews were in the minority, so instead of a synagogue, they would gather at the riverbank on the Sabbath (Acts 16:13). Around 51 ad, Paul (with Silas, Luke, & Timothy) planted a church in Philippi at the home of Lydia (Acts 16:14-15). Some of the core members perhaps included the slave girl and the jailer with his family (Acts 16:16-34). Paul visited Philippi again around 5 years later.
Around 60 ad, Paul was placed under house arrest in Rome. The church in Philippi sent support for Paul’s continued missionary efforts. In response to this, Paul wrote Philippians, a letter (or epistle) to the church in Philippi thanking them for their ministry support. Philippians is also known as the letter/epistle of joy since Paul uses a form of the word “joy” 16 times. Paul does not use any Old Testament quotations, perhaps since the Jews were in the minority at Philippi.
Philippians is an encouraging letter from Paul full of relevant wisdom, including this reminder: “I can do all things through [Christ] who gives me strength” (Philippians 4:13).
