{15} The church that is at {d} Babylon, elected together with you, saluteth you; and so doth Marcus my son.

(15) Familiar salutations.

(d) In that famous city of Assyria, where Peter the apostle of circumcision then was.

People's New Testament

5:13 The church that is at Babylon. She that is in Babylon (Revised Version). The word church is not in the Greek. Peter probably referred to his wife. The salutations are from individuals. On Babylon, see topic 9257. Alford says,

There is no reason whatever for regarding this any place but the Chaldean capital.''

So doth Marcus, my son. Most likely John Mark, the author of the second gospel. See Ac 12:12 13:05 15:37 Col 4:10.

Wesley's Notes

5:13 The church that is at Babylon - Near which St. Peter probably was, when he wrote this epistle. Elected together with you - Partaking of the same faith with you. Mark - It seems the evangelist. My son - Probably converted by St. Peter. And he had occasionally served him, as a son in the gospel.

Jamieson-Fausset-Brown Bible Commentary

13. The . at Babylon-Alford, Bengel, and others translate, "She that is elected together with you in Babylon," namely, Peter's wife, whom he led about with him in his missionary journeys. Compare 1Pe 3:7, "heirs together of the grace of life." But why she should be called "elected together with you in Babylon," as if there had been no Christian woman in Babylon besides, is inexplicable on this view. In English Version the sense is clear: "That portion of the whole dispersion (1Pe 1:1, Greek), or Church of Christianized Jews, with Gentile converts, which resides in Babylon." As Peter and John were closely associated, Peter addresses the Church in John's peculiar province, Asia, and closes with "your co-elect sister Church at Babylon saluteth you"; and John similarly addresses the "elect lady," that is, the Church in Babylon, and closes with "the children of thine elect sister (the Asiatic Church) greet thee"; (compare [2626]Introduction to Second John). Erasmus explains, "Mark who is in the place of a son to me": compare Ac 12:12, implying Peter's connection with Mark; whence the mention of him in connection with the Church at Babylon, in which he labored under Peter before he went to Alexandria is not unnatural. Papias reports from the presbyter John [Eusebius, Ecclesiastical History, 3.39], that Mark was interpreter of Peter, recording in his Gospel the facts related to him by Peter. Silvanus or Silas had been substituted for John Mark, as Paul's companion, because of Mark's temporary unfaithfulness. But now Mark restored is associated with Silvanus, Paul's companion, in Peter's esteem, as Mark was already reinstated in Paul's esteem. That Mark had a spiritual connection with the Asiatic' churches which Peter addresses, and so naturally salutes them, appears from 2Ti 4:11; Col 4:10.

Babylon-The Chaldean Babylon on the Euphrates. See [2627]Introduction, ON THE PLACE OF WRITING this Epistle, in proof that Rome is not meant as Papists assert; compare Lightfoot sermon. How unlikely that in a friendly salutation the enigmatical title of Rome given in prophecy (John, Re 17:5), should be used! Babylon was the center from which the Asiatic dispersion whom Peter addresses was derived. Philo [The Embassy to Gaius, 36] and Josephus [Antiquities, 15.2.2; 23.12] inform us that Babylon contained a great many Jews in the apostolic age (whereas those at Rome were comparatively few, about eight thousand [Josephus, Antiquities, 17.11]); so it would naturally be visited by the apostle of the circumcision. It was the headquarters of those whom he had so successfully addressed on Pentecost, Ac 2:9, Jewish "Parthians . dwellers in Mesopotamia" (the Parthians were then masters of Mesopotamian Babylon); these he ministered to in person. His other hearers, the Jewish "dwellers in Cappadocia, Pontus, Asia, Phrygia, Pamphylia," he now ministers to by letter. The earliest distinct authority for Peter's martyrdom at Rome is Dionysius, bishop of Corinth, in the latter half of the second century. The desirableness of representing Peter and Paul, the two leading apostles, as together founding the Church of the metropolis, seems to have originated the tradition. Clement of Rome [First Epistle to the Corinthians, 4.5], often quoted for, is really against it. He mentions Paul and Peter together, but makes it as a distinguishing circumstance of Paul, that he preached both in the East and West, implying that Peter never was in the West. In 2Pe 1:14, he says, "I must shortly put off this tabernacle," implying his martyrdom was near, yet he makes no allusion to Rome, or any intention of his visiting it.

Matthew Henry's Concise Commentary

5:10-14 In conclusion, the apostle prays to God for them, as the God of all grace. Perfect implies their progress towards perfection. Stablish imports the curing of our natural lightness and inconstancy. Strengthen has respect to the growth of graces, especially where weakest and lowest. Settle signifies to fix upon a sure foundation, and may refer to Him who is the Foundation and Strength of believers. These expressions show that perseverance and progress in grace are first to be sought after by every Christian. The power of these doctrines on the hearts, and the fruits in the lives, showed who are partakers of the grace of God. The cherishing and increase of Christian love, and of affection one to another, is no matter of empty compliment, but the stamp and badge of Jesus Christ on his followers. Others may have a false peace for a time, and wicked men may wish for it to themselves and to one another; but theirs is a vain hope, and will come to nought. All solid peace is founded on Christ, and flows from him.
