I am glad of the coming of Stephanas and Fortunatus and Achaicus: for that which was lacking on your part they have supplied.

People's New Testament

16:17 I am glad of the coming of Stephanas. Stephanas is named in 1Co 1:16 16:15.

And Fortunatus, and Achaicus. The other two are not named elsewhere. These three doubtless brought to Paul the letter referred to in 1Co 7:1 and probably carried back the present letter.

Wesley's Notes

16:17 I rejoice at the coming of Stephanas, and Fortunatus, and Achaiacus - Who were now returned to Corinth but the joy which their arrival had occasioned remained still in his heart. They have supplied what was wanting on your part - They have performed the offices of love, which you could not, by reason of your absence.

Jamieson-Fausset-Brown Bible Commentary

17. Fortunatus . Achaicus-probably of Stephanas' household.

that . lacking on your part-So far as you were unable yourselves to "refresh my spirit," in that you are absent from me, "they have supplied" by coming to me from you, and so supplying the means of intercourse between you and me. They seem to have carried this letter back; see the subscription below: hence the exhortations, 1Co 16:16, 18, as though they would be at Corinth when the Epistle arrived.

Matthew Henry's Concise Commentary

16:13-18 A Christian is always in danger, therefore should ever be on the watch. He should be fixed in the faith of the gospel, and never desert or give it up. By this faith alone he will be able to keep his ground in an hour of temptation. Christians should be careful that charity not only reigns in their hearts, but shines in their lives. There is a great difference between Christian firmness and feverish warmth and transport. The apostle gave particular directions as to some who served the cause of Christ among them. Those who serve the saints, those who desire the honour of the churches, and to remove reproaches from them, are to be thought much of, and loved. They should willingly acknowledge the worth of such, and all who laboured with or helped the apostle.
