“"I commend unto you Phebe our sister, which is a deaconess (A. V. servant) of the church which is at Cenchrea." See how many ways he takes to give her dignity. For he has both mentioned her before all the rest, and called her sister. And it is no slight thing to be called the sister of Paul. Moreover he has added her rank, by mentioning her being "deaconess."”

“"I commend unto you Phebe our sister, which is a deaconess of the church which is at Cenchrea." See how many ways he takes to give her dignity. For he has both mentioned her before all the rest, and called her sister. And it is no slight thing to be called the sister of Paul. Moreover he has added her rank, by mentioning her being "deaconess." "That ye receive her in the Lord, as becometh saints." That is, for the Lord's sake, that she may enjoy honor among you. For he that receives a person for the Lord's sake, though it be no great one that he receives, yet receives him with attention. But when it is a saint, consider what attention he ought to have shown him. And this is why he adds, "as becometh saints," as such persons ought to be received. For she has two grounds for her having attention shown her by you, both that of her being received for the Lord's sake, and that of her being a saint herself. And "that ye assist her in whatsoever business she hath need of you." You see how little he burdens them. For he does not say, That ye despatch, but that ye contribute your own part, and reach out a hand to her: and that "in whatsoever business she hath need." Not in whatsoever business she may be, but in such as she may ask of you. But she will ask in such things as lie in your power. Then again there comes a very great praise of her. "For she hath been a succorer of many and of myself also." See his judgment. First come the encomiums, then he makes an exhortation intervene, and then again gives encomiums, so placing on each side of the needs of this blessed woman her praises. For how can the woman be else than blessed who has the blessing of so favorable a testimony from Paul, who had also the power to render assistance to him who had righted the whole world? For this was the summit of her good deeds, and so he placed it the last, as he says, "and of myself also." But what does the phrase "of myself also" convey? Of the herald of the world, of him who hath suffered so much, of him who is equal to assisting tens of thousands.”

“After the Apostle set forth to the faithful Romans, to whom he was writing, certain personal matters pertaining to himself, here he sets down certain personal matters pertaining to others. And concerning this he does three things. First, he admonishes them what they ought to do toward others; second, he shows what others do toward them, at the words he salutes you, etc.; third, he ends the epistle with a giving of thanks, at the words now to him who is able, etc. Concerning the first he does two things. First he shows whom they ought to greet; second he shows whom they ought to avoid, at the words now I beseech you, brethren. Concerning the first, he commands that certain persons be greeted specifically; second, he sets down in general the manner of greeting, at the words greet one another, etc. Third, he greets them in common on behalf of the faithful, at the words they salute you, etc. Concerning the first, he speaks of a certain Corinthian woman who was going to Rome, whom he commends to them, describing her, first, by name, saying, now I commend to you Phoebe, who, although she was devoted to God, nevertheless was not of such authority that she did not need letters of commendation, just as he himself says of himself in 2 Corinthians 3:1: or do we need, as some do, letters of commendation? Second, he describes her by the religion of faith, saying our sister. For all faithful women are called sisters, just as all men are called brothers. Matthew 23:8: you are all brethren. Third, by the office of piety, when he says who is in the ministry of the Church which is at Cenchreae, the port of the Corinthians, where some Christians were gathered, whom the aforesaid woman served — just as also of Christ himself it is said in Luke 8:3 that certain women ministered to him from their means. And concerning the widow to be chosen it is said in 1 Timothy 5:10: if she has received guests, if she has washed the feet of the saints. Then he states two things in which he wishes her to be held as commended, of which the first is that she be honorably received. And this is what he says: that you receive her in the Lord, that is, for the love of God. Worthily of the saints, that is, according to what is worthy for saints to be received, according to Matthew 10:11: he who receives a just man in the name of a just man shall receive the reward of a just man. Certain books have, worthily enough, that is, fittingly; however this reading does not agree with the Greek. The second is that they help her diligently. Hence he adds that you assist her, namely by bringing counsel and aid in whatever business she may need of you. For perhaps she had some business to transact in Caesar's court. But against this seems to be what is said in 1 Thessalonians 4:11: attend to your own business — as if to say: do not meddle in the affairs of others. But it must be said that assisting in the affairs of others happens in two ways. In one way, in a worldly manner, that is, for the favor of men or for gain, and this does not befit the servants of God. 2 Timothy 2:4: no man serving as a soldier for God entangles himself in secular business. In another way, someone assists in the affairs of others out of piety, as in aid of the needy and the wretched, and this is a religious act, according to James 1:27: pure and undefiled religion before God and the Father is this: to visit orphans and widows in their tribulation. And it is in this way that the Apostle speaks here. Finally, the Apostle shows her merit, why this is owed to her, saying for she also has assisted many, and myself as well. Isaiah 3:10: say to the just man that it is well, for the reward of his hands shall be given to him. Matthew 5:7: blessed are the merciful, for they shall obtain mercy. Then he commands that certain other persons joined to himself be greeted, saying, greet Prisca and Aquila — who was the husband of Prisca, but he places the woman first, perhaps on account of a greater devotion of faith — my helpers in Christ Jesus, that is, in the preaching of the faith of Christ. For he lodged with them at Corinth, as is found in Acts 18:2 and following. Who for my life laid down their own necks, that is, exposed themselves to the danger of death for the preserving of my life, which is a sign of the greatest charity. John 15:13: greater love than this has no one, that a man lay down his life for his friends. Now this seems to have happened at Corinth, where Paul suffered persecution, as is found in Acts 18:6. Or perhaps it must better be said that they exposed themselves to danger for the Apostle. For that which is read in Acts 18:2 took place when Prisca and Aquila, departing from Rome, came to Corinth, as is said in the same place. But the Apostle was writing this when he still supposed them to be at Rome. Now the life of the Apostle was necessary not so much for himself as for others, according to Philippians 1:24: but to remain in the flesh is necessary for your sake. And therefore he adds, to whom not only I give thanks, but also all the churches of the Gentiles — of whom I am the apostle and teacher, 1 Timothy 2:7: teacher of the Gentiles in faith and truth. And also, greet their household church. For they had many of the faithful gathered together in their house. Then he wishes another to be greeted, joined to him in love, saying, greet Epaenetus, beloved to me, who is the first-fruits of Asia in Christ. For he was the first in all of Asia to be converted to the faith of Christ, which was for him a matter of great dignity, Hebrews 12:22-23: you have come to the church of the firstborn, who are enrolled in heaven. But he was then at Rome. Then he says, greet Mary, who has labored much among you, to this end, that she might call them back to concord; and when she was not able to do this, she made it known to the Apostle. Wisdom 3:15: glorious is the fruit of good labors. Then he says, greet Andronicus and Junia, whom, first, he describes by lineage, when he says my kinsmen. In which he shows that they were Jews, concerning whom above, chapter 9:3: who are my kinsmen according to the flesh. Second, by the suffering undergone for Christ, saying and my fellow captives. For they had at some time been imprisoned along with the Apostle of Christ. 2 Corinthians 11:23: in prisons more abundantly. Third, by authority, when he says who are of note among the apostles, that is, noble among the preachers, according to Proverbs, the last chapter: her husband is noble in the gates. Fourth, by time, when he says and were in Christ Jesus before me. For they had been converted before the Apostle himself, and on this account greater reverence was owed to them. 1 Timothy 5:1: rebuke not an elder, but entreat him as a father. Then he says, greet Ampliatus, my beloved in the Lord, namely with the love of charity, which is in Christ. Philippians 1:8: God is my witness, how I long for you all in the bowels of Christ. Then he says, greet Urbanus, our helper in Christ, namely in the preaching of the faith, Proverbs 18:19: a brother who is helped by a brother, etc. And Stachys, my beloved, whom he joins together, because perhaps they dwelt together, or were joined by some other bond of relationship. Then he says, greet Apelles, approved in Christ, that is, tested in Christ, perhaps through some tribulations. Job 23:10: he has tried me as gold that passes through fire. Then he says, greet all who are of the household, that is, of the family of Aristobulus, in whose house many of the faithful were gathered together; he does not greet Aristobulus himself, because perhaps for some reason he was absent. Then he says, greet Herodion, my kinsman, who from this very fact is said to have been a Jew. Then he says, greet all who are of the household of Narcissus, who is said to have been a priest and to have traveled through desert places in order to strengthen the faithful of Christ. Hence, because the Apostle knew that he was at that time absent, he does not command that he himself be greeted, but his household. There were, however, in his household some unbelievers, and therefore, for the sake of distinction, he adds who are in the Lord, because he commands only the faithful to be greeted. 2 John 10: if anyone comes to you and does not bring this doctrine, do not receive him into your house, nor say to him, greetings. Then he says, greet Tryphaena and Tryphosa, who have labored in the Lord, that is, in the ministry of the saints, which the Lord reckons as done to himself, according to Matthew 25:40: what you have done to one of the least of mine, you have done to me. Then he says, greet Persis, my dearest, whom the Apostle especially loved on account of her devotion. Hence he adds who has labored much in the Lord, namely by exhorting others and ministering to the saints, and also in poverty and other spiritual labors. 2 Corinthians 11:27: in labors, in fastings, in watchings, etc. Then he says, greet Rufus, chosen in the Lord, that is, in the grace of Christ, Ephesians 1:4: he chose us in him before the foundation of the world — and his mother, namely according to the flesh, and mine, because she was his mother by kindness. For she had at some time served the Apostle, although she was not then at Rome. 1 Timothy 5:2: older women as mothers, younger women as sisters, in all chastity. Then he says, greet Asyncritus, Hermes, Patrobas, Hermas, and the brethren who are with them, whom he greets together, because they lived together in harmony. Psalm 67:6: who makes those of one manner to dwell in a house. Then he says, greet Philologus and Julia, Nereus and his sister Olympias, and all the saints who are with them, that is, sanctified in the faith of Christ. 1 Corinthians 6:11: you have been washed and you have been sanctified. Then he shows the manner in which they should generally greet one another, saying, greet one another with a holy kiss, which is said in distinction from the lustful kiss, of which it is said in Proverbs 7:13: having caught hold of him, she kisses the young man. And also in distinction from the deceitful kiss, of which it is said in Proverbs 27:6: better are the wounds of one who loves, than the deceitful kisses of an enemy. Now a holy kiss is one that is given as a sign of the Holy Trinity. Song of Songs 1:1: let him kiss me with the kiss of his mouth. From this, moreover, a custom grew up in the Church that the faithful should give one another kisses of peace during the solemnities of the Mass. Then he greets them on behalf of the other churches, saying, all the churches of Christ salute you, that is, those gathered in the name and faith of Christ, because they all desire your welfare and pray for you. James, the last chapter: pray for one another, that you may be saved.”

“I commend unto you Phebe our sister,.... This chapter chiefly consists of commendations and salutations of persons, and begins with the former. It was usual to give letters of commendation of a member of one church to those of another; see Co2 3:1; The person who is here recommended was, as appears from the subscription of this epistle, if that may be depended on, the bearer of this letter, and is described by her name, Phebe; as she dwelt at Cenchrea, it is probable she was a Grecian, as is her name. Pausanias (e) makes frequent mention of one of this name in Greece. With the Heathen poets, Pheobus was the sun, and Phoebe the moon. Though it is not unlikely that she might be a Jewess, since there were many of them in those parts; and this was a name in use among them. We often read (f) of R. Ishmael , "ben Phoebi", which I take to be the same name with this. She is recommended as a sister, "our sister"; not in a natural, but spiritual relation; one that was a member of the church at Cenchrea, and in full communion with it; for as it was usual to call the men brethren, it was common to call the women sisters. Elderly men were called fathers, younger men brethren; elderly women were styled mothers, and younger women sisters, who were partakers of the grace of God, and enjoyed the fellowship of the saints: which is a servant of the church which is at Cenchrea. This place was a seaport of the Corinthians, distant from Corinth about seventy furlongs, or eight or nine miles: it was on one side of the Isthmus, as Lechea was on the other (g); See Gill on Act 18:18. In the way to this place from the Isthmus, as Pausanias relates (h), was the temple of Diana, and a very ancient sculpture; and in Cenchrea itself was the temple of Venus, and a wooden image; and near the flow of the sea was a Neptune of brass. But now, in this place, was a church of Jesus Christ; and since it was so near to Corinth, it shows that churches in those early times were not national, or provincial, but congregational. Of this church Phebe was a servant, or, as the word signifies, a minister or deacon; not that she was a teacher of the word, or preacher of the Gospel, for that was not allowed of by the apostle in the church at Corinth, that a woman should teach; see Co1 14:34; and therefore would never be admitted at Cenchrea. Rather, as some think, she was a deaconess appointed by the church, to take care of the poor sisters of the church; though as they were usually poor, and ancient women; that were put into that service, and this woman, according to the account of her, being neither poor, nor very ancient; it seems rather, that being a rich and generous woman, she served or ministered to the church by relieving the poor; not out of the church's stock, as deaconesses did, but out of her own substance; and received the ministers of the Gospel, and all strangers, into her house, which was open to all Christians; and so was exceeding serviceable to that church, and to all the saints that came thither: though it is certain that among the ancient Christians there were women servants who were called ministers. Pliny, in an epistle of his to Trajan the emperor, says (i), that he had examined two maids, "quae ministrae dicebantur", "who were called ministers", to know the truth of the Christian religion.

“I commend unto you Phoebe - As the apostle had not been at Rome previously to his writing this epistle, he could not have had a personal acquaintance with those members of the Church there to whom he sends these friendly salutations. It is likely that many of them were his own converts, who, in different parts of Asia Minor and Greece, had heard him preach the Gospel, and afterwards became settlers at Rome. Phoebe is here termed a servant, διακονον, a deaconess of the Church at Cenchrea. There were deaconesses in the primitive Church, whose business it was to attend the female converts at baptism; to instruct the catechumens, or persons who were candidates for baptism; to visit the sick, and those who were in prison, and, in short, perform those religious offices for the female part of the Church which could not with propriety be performed by men. They were chosen in general out of the most experienced of the Church, and were ordinarily widows, who had borne children. Some ancient constitutions required them to be forty, others fifty, and others sixty years of age. It is evident that they were ordained to their office by the imposition of the hands of the bishop; and the form of prayer used on the occasion is extant in the apostolical constitutions. In the tenth or eleventh century the order became extinct in the Latin Church, but continued in the Greek Church till the end of the twelfth century. See Broughton's Dictionary, article deaconess. Cenchrea was a sea-port on the east side of the isthmus which joined the Morea to Greece, as the Lechaeum was the sea-port on the west side of the same isthmus. These were the only two havens and towns of any note, next to Corinth, that belonged to this territory. As the Lechaeum opened the road to the Ionian sea, so Cenchrea opened the road to the Aegean; and both were so advantageously situated for commerce that they were very rich. These two places are now usually denominated the Gulf of Lepanto, and the Gulf of Ingia or Egina. It was on the isthmus, between these two ports, which was about six miles wide, that the Isthmian games were celebrated; to which St. Paul makes such frequent allusions.”

“I commend, &c. He concludes with a number of salutations, to show his affection for them. — Phœbe, who is in the ministry, or employed in the ministry, as women, called diaconissæ, used to be, privately instructing catechumens, assisting particularly at the baptizing of women, distributing charities, &c.
