THE EPISTLE TO THE PHILIPPIANS The City of Philippi and the Church.--This city is notable from the fact that it was the first, in Europe, in which the gospel tidings were made known. Accounts of how Paul came to visit Macedonia and to begin the work in Philippi are given in Acts (16:10, 12-40). Going out of the city as he did by the river side, where prayer was wont to be made, and talking to a number of women about the "New Way" would not seem to be a very favorable beginning for a movement which was to produce such exceedingly large results. But Paul was so full of zeal for Christ that he seized every opportunity, no matter how small, to make Him known. This church afterwards was a great comfort to the Apostle. This letter shows how he loved it and how he exhorted them to rejoice in the Lord (4:4). +Occasion.+--Paul was in prison in Rome. The Philippian converts were greatly concerned about him, therefore they sent Epaphroditus with gifts and offerings to him (4:18). This was not the first time that they had taken thought of and remembered their founder, in a similar way (4:15, 16). The Apostle was very grateful for their care (4:10-14). While in Rome, Epaphroditus was taken very sick and came near death (2:25-28). As soon as he had recovered from his sickness Paul sent him back to Philippi (2:28), with this letter. The reference to Caesar's household shows how strong a hold Christianity was getting in Rome (4:22; 1:12-14), and that there was great boldness in proclaiming the gospel. +Objects.+--It is an Epistle of thanks to the Philippians for their kindness (4:10-18) in remembering the Apostle with substantial gifts in his work and for their fellowship (1:5) in the gospel.
