The children of thy elect sister greet thee. Amen.

People's New Testament

1:13 The children of thy elect sister. It is usually supposed that this refers to a sister in the flesh, also one of the elect, whose children, probably grown up and Christians, were at that time with John.

Wesley's Notes

1:13 The children of thy elect or Christian sister - Absent, if not dead, when the apostle wrote this.

Jamieson-Fausset-Brown Bible Commentary

13. Alford confesses that the non-mention of the "lady" herself here seems rather to favor the hypothesis that a Church is meant.

Matthew Henry's Concise Commentary

1:12,13 The apostle refers many things to a personal meeting. Pen and ink were means of strengthening and comforting others; but to see each other is more so. The communion of saints should be maintained by all methods; and should tend to mutual joy. In communion with them we find much of our present joy, and look forward to happiness for ever.

Matthew Henry's Whole Bible Commentary

Verses 12-13

The apostle concludes this letter, 1. With an adjournment of many things to personal conference: Having many things to write unto you I would not write with paper and ink; but I trust to come unto you, and speak face to face, that our joy may be full. Here it is supposed that some things are better spoken than written. The use of pen and ink may be a mercy and a pleasure; but a personal interview may be more so. The apostle was not yet too old for travel, nor consequently for travelling service. The communion of saints should be by all methods maintained; and their communion should tend to their mutual joy. Excellent ministers may have their joy advanced by their Christian friends. That I may be comforted together with you by the mutual faith both of you and me, Rom. 1:12. 2. With the presentation of service and salutation from some near relations to the lady: The children of thy elect sister greet thee. Grace was abundant towards this family; here are two elect sisters, and probably their elect children. How will they admire this grace in heaven! The apostle condescends to insert the nieces' duty (as we should call it), or dutiful salutation, to their aunt. The duty of inferior relations is to be cherished. Doubtless the apostle was easy of access, and would admit all friendly and pious communication, and was ready to enhance the good lady's joy in her nieces as well as in her children. May there by many such gracious ladies rejoicing in their gracious descendants and other relations! Amen.
