To him be the glory and the power forever and ever. Amen.

 Although it sounds so simple, this is a troublesome verse. It presents us with certain questions difficult of solution. (i) From whom are these greetings sent? The King James Version has "the Church that is at Babylon elected together with you, saluteth you." But "the Church that is" is in italics, which means that there is no equivalent in the Greek which simply says "the one elected together with you at Babylon" and the phrase is feminine. There are two possibilities. (a) It is quite possible that the King James Version is correct. That is the way Moffatt takes it when he translates "your sister Church in Babylon." The phrase could well be explained as being based on the fact that the Church is the Bride of Christ and may be spoken of in this way. On the whole, the commonest view is that it is a Church which is meant. (b) But it does have to be remembered that there is actually no word for Church in the Greek, and this feminine phrase might equally well refer to some well-known Christian lady. If it does, by far the best suggestion is that the reference is to Peter's wife. We know that she did actually accompany him on his preaching journeys ( 1 Corinthians 9:5). Clement of Alexandria (Stromateis 7.11.63) tells us that she died a martyr, executed in Peter's own sight, while he encouraged her by saying, "Remember the Lord." She was clearly a well-known figure in the early church. We would not wish to speak dogmatically on this question. It is perhaps more likely that the reference is to a Church; but it is not impossible that Peter is associating his wife and fellow-evangelist in the greetings which he sends. (ii) From where was this letter written? The greetings are sent from Babylon. There are three possibilities. (a) There was a Babylon in Egypt, near Cairo. It had been founded by Babylonian refugees from Assyria and was called by the name of their ancestral city. But by this time it was almost exclusively a great military camp; and in any event the name of Peter is never connected with Egypt. This Babylon may be disregarded. (b) There was the Babylon in the east to which the Jews had been taken in captivity. Many had never come back and it was a centre of Jewish scholarship. The great commentary on the Jewish Law is called the Babylonian Talmud. So important were the Jews of Babylon that Josephus had issued a special edition of his histories for them. There is no doubt that there was a large and important colony of Jews there; and it would have been quite natural for Peter, the apostle of the Jews, to preach and to work there. But we do not find the name of Peter ever connected with Babylon and there is no trace of him having ever been there. Scholars so great as Calvin and Erasmus have taken Babylon to be this great eastern city but, on the whole, we think the probabilities are against it. (c) Regularly Rome was called Babylon, both by the Jews and by the Christians. That is undoubtedly the case in the Revelation where Babylon is the great harlot, drunk with the blood of the saints and the martyrs ( Revelation 17:1-18; Revelation 18:1-24). The Godlessness, Just and luxury of ancient Babylon were, so to speak, reincarnated in Rome. Peter is definitely connected in tradition with Rome; and the likelihood is that it was from there that the letter was written. (iii) Who is the Mark, whom Peter calls his son, and from whom he sends greetings? If we take the elect lady to be Peter's wife. Mark might quite well be literally Peter's son. But it is much more likely that he is the Mark who wrote the gospel. Tradition has always closely connected Peter with Mark, and has handed down the story that he was intimately involved with Mark's gospel. Papias, who lived towards the end of the second century and was a great collector of early traditions, describes Mark's gospel in this way: "Mark, who was Peter's interpreter, wrote down accurately though not in order, all that he recollected of what Christ had said or done. For he was not a hearer of the Lord or a follower of his; he followed Peter, as I have said, at a later date, and Peter adapted his instructions to practical needs, without any attempt to give the Lord's words systematically. So that Mark was not wrong in writing down some things in this way from memory, for his one concern was neither to omit nor to falsify anything he had heard." According to Papias, Mark's gospel is nothing other than the preaching material of Peter. In similar vein Irenaeus says that after the death of Peter and Paul at Rome, "Mark, the disciple and interpreter of Peter, also handed down to us in writing what had been preached by Peter." It is the consistent story of tradition that Mark, the evangelist, was indeed a son to Peter, and all the likelihood is that these greetings are from him. So, then, we may gather up the possibilities. "She who is at Babylon, and who has been chosen, as you have been chosen," may either be the Church or the wife of Peter, herself a martyr. Babylon may be the Babylon of the east but is more likely to be the great and wicked city of Rome. Mark might possibly be the actual son of Peter, about whom we know nothing else, but is more likely to be Mark, the writer of the gospel, who was to Peter as a son.
