1. Here you have enumerated again a long list of eminently good works enjoined upon Christians who believe and have confessed their faith in the Gospel. By such fruits is faith to be manifest. Peter classifies these works according to the obligations of Christians to each other, and their obligations to enemies and persecutors.
2. Immediately preceding the text, Peter has been instructing concerning the domestic relations of husband and wife; how they should live together as Christians in love and companionship, giving due honor and patiently and reasonably bearing with each other. Now he extends the exhortation to Christians in general, enjoining them to live together in Christian love, like brothers and sisters of a household. In the rehearsal of many preëminently noble virtues and works, he portrays the ideal church, beautiful in its outward adornment, in the grace wherewith it shines before men. With such virtues the Church pleases and honors God, while angels behold with joy and delight. And what earthly thing is more desirable to man's sight? What happier and more pleasing society may he seek than the company of those who manifest a unity of heart, mind and will; brotherly love, meekness, kindliness and patience, even toward enemies? Surely, no man is too depraved to command such goodness and to desire companionship among people of this class.
3. The first virtue is one frequently mentioned by the apostles. Paul, for instance, in Romans 12, 16, says: "Be of the same mind one toward another." Also in Ephesians 4, 3: "Giving diligence to keep the unity of the Spirit in the bond of peace." Harmony is the imperative virtue for the Christian Church. Before the other virtues—love, meekness—can be manifest, there must first be concord and unity of heart among all. It is impossible that outward circumstances of human life be always the same; much dissimilarity in person, station, and occupation is inevitable.
To this very unlikeness and to the natural depravity of flesh and blood is due the discord and disagreement of men in this world. Let one become conscious of personal superiority in point of uprightness, learning, skill or natural ability, or let him become aware of his loftier station in life, and he immediately grows self-complacent, thinks himself better than his fellows, demands honor and recognition from all men, is unwilling to yield to or serve an inferior and thinks himself entitled to such right and privilege because of his superiority and virtue.
4. Pride is the common vice of the world, and the devil fosters it among his numerous followers thereby causing every sort of misery and unhappiness, corrupting all ranks and stations, and rendering men vicious, depraved and incapable of executing good. In opposition to this vice the apostles diligently admonish Christians to be of one mind, regardless of station or occupation, since every individual must remain in the position to which he has been ordained and called of God. All ranks and stations cannot be one. Particularly is this true in the Church; for in addition to the outward difference of person, station, and so on, there are manifold divine gifts unequally distributed and varyingly imparted. Yet these many dissimilarities, both spiritual and secular, are to be amenable to the unity of the spirit, as Paul calls it, or a spiritual unity. Just as the members of the physical body have different offices and perform different functions, no one member being able to do the work of the other, and yet all are in the unity of one bodily life; so also Christians, whatever the dissimilarity of language, office and gift among them, must live, increase and be preserved in unity and harmony of mind, as in one body.
5. This matter of harmony is the first and most necessary commandment enjoined by the doctrine of faith; ay, this virtue is the first fruit which faith is to effect among Christians, who are called in one faith and baptism. It is to be the beginning of their Christian love. For true faith necessarily creates in all believers the spirit that reasons: "We are all called by one Word, one baptism and Holy Spirit, to the same salvation; we are alike heirs of the grace and the blessings of God. Although one has more and greater gifts than another, he is not on that account better before God. By grace alone, without any merit of ours, we are pleasing to God. Before him none can boast of himself."
6. How can I think myself better than another by reason of my person or my gifts, rank or office? Or what more than I has another to boast of before God concerning himself? No one has a different baptism or sacrament, a different Christ, from mine, or grace and salvation other than I have. And no individual can have another faith than have Christians in general, nor does he hear any other Gospel or receive a different absolution, be he lord or servant, noble or ignoble, poor or rich, young or old, Italian or German. When one imagines himself different from or better than his fellows, desiring to exalt and glorify himself above others, he is truly no longer a Christian; because he is no longer in that unity of mind and faith essential to Christians. Christ with his grace is always the same, and cannot be divided or apportioned within himself.
7. Not without reason did the beloved apostles urge this point. They clearly saw how much depends upon it, and what evil and harm result from disregard of the commandment. Where this commandment is dishonored, schisms and factions will necessarily arise to corrupt pure doctrine and faith, and the devil will sow his seed, which afterwards can be eradicated only with difficulty. When once self-conceit rules, and one, pretending more learning, wisdom, goodness and holiness than his fellows, begins to despise others and to draw men to himself, away from the unity of mind which makes us one in Christ, and when he desires the first praise and commendation for his own doctrine and works, his own preaching, then the harm is already done; faith is overthrown and the Church is rent. When unity becomes division, certainly two sects cannot both be the true Church. If one is godly, the other must be the devil's own. On the other hand, so long as unity of faith and oneness of mind survives, the true Church of God abides, notwithstanding there may be some weakness in other points. Of this fact the devil is well aware; hence his hostility to Christian unity. His chief effort is to destroy harmony. "Having that to contend with," he tells himself, "my task will be a hard and wearisome one."
8. Therefore, Christians should be all the more careful to cherish the virtue of harmony, both in the Church and in secular government. In each instance there is of necessity much inequality. God would have such dissimilarity balanced by love and unity of mind. Let everyone be content, then, with what God has given or ordained for him, and let him take pleasure in another's gifts, knowing that in eternal blessings he is equally rich, having the same God and Christ, the same grace and salvation; and that although his standing before God may differ from that of his fellows, he is nevertheless in no way inferior to them, nor is anyone for the same reason at all better than or superior to himself.
9. In temporal affairs, every inequality in the world can be harmonized by a unity of mind and heart. In relations other than spiritual there is mutual love and friendship. How great the outward dissimilarity between man and wife—in person, nature and employment! likewise between masters and their subjects. Yet, in mutual conscientiousness they mutually agree and are well satisfied with each other. So it would be possible to enjoy life upon earth in peace and happiness were it not that the devil cannot suffer it. He must divide hearts and alienate love, allowing no one to take pleasure in another. He who is illustrious, of noble birth, or has power or riches, feels bound to despise others as silly geese or witless ducks.
