Phil. 4:21. Greet every saint in Christ Jesus.
A sign of no small goodwill is to greet them by means of epistles.
Phil. 4:21. Greet you the brethren who are with me.
For with him were many, perhaps even some from Rome itself, who nevertheless did not take part in apostolic affairs: such was only Timothy, whom he called above like-minded with himself. Nevertheless, he does not refuse to call them brothers.
Phil. 4:22. All the saints greet you, and especially those of Caesar's household.
Those from Caesar's household he commended and encouraged them, showing that piety had reached even the royal house, suggesting that if those at the imperial court disregarded everything for the sake of Christ, then all the more should you—simple people—do the same. At the same time, he makes known that he spoke of the virtue of the Philippians before Caesar's household; for otherwise he could not have aroused in the latter the goodwill that was expressed in their greeting.
Phil. 4:23. The grace of our Lord Jesus Christ be with you all. Amen.
According to his custom, he concludes the epistle with a prayer. And he teaches at the same time to attribute to the grace of Christ whatever virtues they possess, and not to be puffed up by them. For only then will grace abide with them forever, if they do not become conceited. May there abound among us as well, by the grace of Christ, every other virtue, and especially the virtue of giving aid to others, so that we too, receiving benefit from assisting all those in need, and particularly those who suffer for God's sake, may enjoy the riches of His goodness. To Him be glory and dominion, now and ever and unto the ages. Amen.
