John Chrysostom
"So," in what manner? As you stood unbending. See how, after the exhortation, he adds praises: "my joy and crown." Not only joy, but glory; not only glory, but a crown.
Nothing is equal to that glory, when they make up Paul's crown. "So stand in the Lord, beloved," that is, in hope in God. "I entreat Euodia, and I entreat Syntyche, to be of the same mind in the Lord."
