_Above all things being fervent in your love among yourselves._ Soundness of mind and sobriety should dominate every part of the believer's life; but there are other virtues of pre-eminent excellence, unto which, though they be far above him, he is encouraged to aspire. Of these St. Peter, like St. Paul (1 Cor. xiii. 13), places love at the summit, above all things. The word he uses signifies that perfect love which is the attribute of God Himself. To frail humanity it must ever be an ideal. But the Apostle in his second epistle (2 Peter i. 7) has given a progressive list of graces to be sought after in a holy life, a series of mountain summits each above the other, and each made visible through the one below it. Here, too, love comes as the climax; and the Revised Version marks it as far above mere human affection: "In your love of the brethren supply also love." Here is no anticlimax, if we once appreciate the grandeur of the concluding term.
In the present verse, however, the Apostle exhorts that this Divine quality is to be exercised by the converts among themselves, and exercised with much earnestness and diligence. It is to be the grace which pervades all their lives, and extends itself to every condition thereof. But we understand why St. Peter has used this word for love as soon as we come to the clause which follows: _For love covereth a multitude of sins_. To cover sin is Godlike. It has been often asked, Whose sins are covered by this love, those of him who loves, or of him who is loved? The question can have but one answer. There is nothing in the New Testament to warrant such a doctrine as that love towards one's fellow-men will hide, atone for, or cancel any man's sins. When our Lord says of the woman who was a sinner, "Her sins, which are many, are forgiven; for she loved much" (Luke vii. 47), it is not love to the brethren of which He is speaking, but love to God, which she had manifested by her actions toward Himself; and when He presently adds, "Thy faith hath saved thee," He tells us the secret of her availing love. But when men are animated by that love toward their neighbours which shows likest God's, they are tender to their offences; they look to the future more than to the past, hoping all things, believing all things; they have tasted God's mercy in the pardon of their own sins, and labour to do thus unto others, to cast their sins out of sight, to put them, as God does when He forgives, behind their back, as though in being forgiven they were also forgotten. The phrase is quoted by St. Peter from Prov. x. 12, where Solomon says, "Love covereth _all_ sins," and our Lord's words to St. Peter himself (Matt. xviii. 22) about forgiving until seventy times seven times practically set no limit to the extension of pardon to the repentant. Thus taught, the Apostle uses the noble word ἀγάπη of human tenderness to offenders, because he would urge men to a boundless, all-embracing, Godlike pity for sinners.
_Using hospitality one to another without murmuring._ We need only reflect on the narrative of the Acts of the Apostles to realise how large a part hospitality must have played in the early Church as soon as the preachers extended their labours beyond Jerusalem. The house of Simon the tanner, where Peter was entertained many days (ix. 43); the friends who at Antioch received Paul and Barnabas and kept them for a whole year (xi. 26); the petition of Lydia, "Come into my house, and abide there" (xvi. 15); and Jason's reception of Paul and Silas at Thessalonica (xvii. 7), are but illustrations of what must have been the general custom. Nor would such welcome be needed for the Apostles alone. The Churches must have been very familiar with cases of brethren driven from their own country by persecution, or severed from their own kinsfolk by the adoption of the new faith. To such the kind offices of the Christian congregations must have been constantly extended, so that hospitality was consecrated into a blessed and righteous duty. To be "given to hospitality" (Rom. xii. 13) is reckoned among the marks whereby it shall be known that believers, being many, are one body in Christ; and from the salutations in the last chapter of the Epistle to the Romans we can frame a picture of the large work of lodging and caring for strangers as it entered into the duties of a Christian life. The brethren at Rome are exhorted to receive and help Phœbe, the bringer of the Epistle, because she had been a succourer of many, and of Paul himself. Of Priscilla and Aquila, who are next named, we know that they were friends and fellow-workers with St. Paul in Corinth, and that in Ephesus they showed their Christian love toward the stranger Apollos; and not only so, but they provided a place where the brethren might assemble for their worship. Later on is mentioned Mary, who bestowed much labour on the brethren, Urbanus, a helper in Christ, and the households of Aristobulus and Narcissus, whole families made friends through the extension of hospitality. Of the mother of Rufus St. Paul speaks tenderly as his own mother also. The coupling together of Philologus and Julia suggests that they were husband and wife and had opened their doors to the brethren, and the notice of Nereus and his sister points to similar good offices. And from whatever place the Epistle was sent to Rome, there Tertius, St. Paul's amanuensis, was under the hospitable roof of Gaius, whom he speaks of as the host of the whole Church. Doubtless at times the burden might fall heavily on some of the poorer brethren. Hence the need for the Apostle's addition _without murmuring_. The word is the same which is used (Acts vi. 1) of the complaints of the Grecians. And in this matter, as in all, a sound mind would be called for, that loads might be placed by the Churches only on such as were able to bear them.
