John Chrysostom
See how the Apostle again turns to glorious women. After saying, “Greet the faithful,” he again begins to greet women, saying, “Greet Tryphaena and Tryphosa, who labor in the Lord.”
Of Mary the Apostle says, “she labored for us.” Of these women he says that they are still laboring.
This is no small praise, always to be at work and not only to assist, but also to labor.
The Apostle calls Persis beloved, showing that she is higher than those mentioned before her.
He says, “Greet the beloved Persis,” and testifies to her many labors with these words: “who labored much in the Lord.”
Thus he knew how to name each according to worth. He encouraged some to greater zeal by depriving no one of what belonged to him.
He proclaimed even the smallest advantage of each. He made others more zealous by kindling in them, through his praises, rivalry toward the works of the first.
