He sets forth five praiseworthy traits in him. "Brother," as a Christian, and perhaps also as one who, through repeated meetings, had drawn nearer to the Apostle than others. "Fellow worker," as a co-laborer in preaching the Gospel and spreading the faith. Evidently he helped St. Paul in establishing the faith and founding the Church in Philippi. Perhaps he was entrusted with continuing what the Apostle had begun after Paul left there. He also helped bring it about that the Philippian Church proved so devoted to St. Paul and to the faith. "Fellow soldier," already because he was a fellow worker. For the spread of the Gospel is a true struggle against the darkness of impiety and corrupt morals. More directly, this means that he suffered together with the Apostle for the Gospel. He was a fellow soldier as a fellow participant with the Apostle in troubles and afflictions, see St. Chrysostom. Where and when this occurred is not clear. Perhaps by this the Apostle meant that, in matters of faith and the Church, he was exposed to mortal danger here in Rome. Perhaps he also endured much at home in Philippi. If it is said of all the Philippians that it was given to them not only to believe, but also to suffer, then prominent men, such as Epaphroditus, certainly received far more. "Messenger" directly, according to the flow of the discourse, gives the thought that he was sent from the Philippians to the Apostle. He is your messenger, that is, your envoy. Thus Oecumenius. Yet he may also be called their Apostle in the sense that he taught them, continuing among them Paul's apostolic work. Thus St. Chrysostom and Theophylact. Or because care for them was entrusted to him. Thus Theodoret. "Minister to my need," as the one who brought from the Philippians what St. Paul needed. The word by which he is called here, λειτουργος, suggests that St. Paul regarded this kind of service as a sacred ministry. This is fitting, because it aided the success of the preaching of the Gospel. Elsewhere in St. Paul, that preaching is called a sacred ministry, see Rom. 15:16.
