This is a summary of what is gone before; for he intimates that God is not feared, nor their just right rendered to men, except civil order prevails among us, and magistrates retain their authority. That he bids honor to be rendered to all, I explain thus, that none are to be neglected; for it is a general precept, which refers to the social intercourse of men. [1] The word honor has a wide meaning in Hebrew, and we know that the apostles, though they wrote in Greek, followed the meaning of words in the former language. Therefore, this word conveys no other idea to me, than that a regard ought to be had for all, since we ought to cultivate, as far as we can, peace and friendship with all; there is, indeed, nothing more adverse to concord than contempt. What he adds respecting the love of brethren is special, as contrasted with the first clause; for he speaks of that particular love which we are bidden to have towards the household of faith, because we are connected with them by a closer relationship. And so Peter did not omit this connection; but yet he reminds us, that though brethren are to be specially regarded, yet this ought not to prevent our love from being extended to the whole human race. The word fraternity, or brotherhood, I take collectively for brethren. Fear God I have already said that all these clauses are applied by Peter to the subject he was treating. For he means, that honor paid to kings proceeds from the fear of God and the love of man; and that, therefore, it ought to be connected with them, as though he had said, "Whosoever fears God, loves his brethren and the whole human race as he ought, and will also give honor to kings." But, at the same time, he expressly mentions the king, because that form of government was more than any other disliked; and under it other forms are included.

Footnotes

1 - It is better to take it in this wide sense, than to limit it, as some have done, to rulers or magistrates, because honor to magistrates is included in the last clause, "Honour the king." -- Ed.

Honor all men - That is, show them the respect which is due to them according to their personal worth, and to the rank and office which they sustain. See the notes at Romans 13:7.
Love the brotherhood - The whole fraternity of Christians, regarded as a band of brothers. The word used here occurs only in this place and in 1-Peter 5:9, where it is rendered "brethren." The idea expressed here occurs often in the New Testament. See the notes at John 13:34-35.
Fear God - A duty everywhere enjoined in the Bible, as one of the first duties of religion. Compare Leviticus 25:17; Psalm 24:7; Psalm 25:14; Proverbs 1:7; Proverbs 3:13; Proverbs 9:10; Proverbs 23:17; See the Romans 3:18 note; 2-Corinthians 7:1 note. The word fear, when used to express our duty to God, means that we are to reverence and honor him. Religion, in one aspect, is described as the fear of God; in another, as the love of God; in another, as submission to his will, etc. A holy veneration or fear is always an elementary principle of religion. It is the fear, not so much of punishment as of his disapprobation; not so much the dread of suffering as the dread of doing wrong.
Honor the king - Referring here primarily to the Roman sovereign, but implying that we are always to respect those who have the rule over us. See the notes at Romans 13:1-7. The doctrine taught in these verses Romans 13:13-14 is, that we are faithfully to perform all the relative duties of life. There are duties which we owe to ourselves, which are of importance in their place, and which we are by no means at liberty to neglect. But we also owe duties to our fellow-men, to our Christian brethren, and to those who have the rule over us; and religion, while it is honored by our faithful performance of our duty to ourselves, is more openly honored by our performance of our duties to those to whom we sustain important relations in life. Many of the duties which we owe to ourselves are, from the nature of the case, hidden from public observation. All that pertains to the examination of the heart; to our private devotions; to the subjugation of our evil passions; to our individual communion with God, must be concealed from public view. Not so, however, with those duties which pertain to others. In respect to them, we are open to public view. The eye of the world is upon us. The judgment of the world in regard to us is made up from their observation of the manner in which we perform them. If religion fails there, they judge that it fails altogether; and however devout we may be in private, if it is not seen by the world that our religion leads to the faithful performance of the duties which we owe in the various relations of life, it will be regarded as of little value.

Honour all men - That is, Give honor to whom honor is due, Romans 13:7. Respect every man as a fellow creature, and as one who may be a fellow heir with you of eternal life; and therefore be ready to give him every kind of succor in your power.
Love the brotherhood - All true Christians, who form one great family of which God is the head.
Fear God - Who gives you these commandments, lest he punish you for disobedience.
Honour the king - Pay that respect to the emperor which his high authority requires, knowing that civil power is of God; that the authority with which he, in the course of his providence, has invested him, must be respected in order to its being obeyed; and that if the man be even bad, and as a man be worthy of no reverence, yet he should be respected on account of his office. If respect be banished, subordination will flee with it, and anarchy and ruin will rise up in their place. Truly religious persons are never found in seditions. Hypocrites may join themselves with any class of the workers of iniquity, and say, Hail, brethren!

(20) (d) Honour all [men]. Love the (e) brotherhood. Fear God. Honour the king.
(20) He divides the civil life of man, by occasion of those things of which he spoke, into two general parts: that is, into those duties which private men owe to private men, and especially the faithful to the faithful, and into that subjection by which inferiors are bound to their superiors, but so that kings are not made equal to God, seeing that fear is due to God, and honour to kings.
(d) Be charitable and dutiful towards all men.
(e) The assembly and fellowship of the brethren. (Zac 11:14)

Honour all men,.... To whom honour is due, according to the place, station, and circumstances in which they are, the gifts of providence and grace bestowed on them, and the usefulness they are of, whether they be Jews or Gentiles, rich or poor, believers or unbelievers: it is a saying of Ben Zoma (e),
"who is to be honoured, or is worthy of honour , "he that honoureth creatures";
meaning men in general, or the Gentiles particularly, who were sometimes so called by the Jews; See Gill on Mark 16:15, and may be meant by "all men" here:
love the brotherhood; or "your brethren", as the Syriac version renders it: the whole company of the brethren in Christ, who are born of God, are members of Christ, and of the same body, and have the same spirit, belong to the same family, and are of the household of faith, let them be of whatsoever nation, or in whatsoever circumstances of life. The Jews had not that good opinion of, nor that affection for the Gentiles, but were ready to treat them with indifference, neglect, and contempt; and not only those that knew not God, but even believing Gentiles themselves; and which is the reason of these exhortations, that they should despise no man, but honour all; and especially should express their love, both by words and deeds, to those that were in the same spiritual relation with them, and that without any difference, on account of their being of another nation:
fear God; not with a servile, but a filial fear, the new covenant grace of fear; which springs from the goodness of God, has that for its object, and is increased by the fresh instances and discoveries of it; and which shows itself in a reverential affection for God, a strict regard to his worship and ordinances, and a carefulness of offending him. This is placed between what goes before, and follows after, to show the influence it has on each of them; for where the fear of God is, there will be due respect shown to all men, more or less, and an hearty and affectionate love to all the saints, as brethren, and a proper regard to those that are set in high places of dignity and power:
honour the king; Caesar, the Roman emperor, though a wicked, persecuting Nero, and so any other king or governor; who, so far as he acts the part of a civil magistrate, preserves the peace, the property, and liberty of his subjects, is a terror to evil works, and an encourager of good ones, and rules according to the laws of God, and civil society, is deserving of great honour and esteem from men; and which is to be shown by speaking well of him; by a cheerful subjection to him; by an observance of the laws, and by payment of tribute, and doing everything to make him easy, and honourable in his government: advice much like this is given by Isocrates (f),
"fear God, honour parents, revere friends, and obey the laws.
(e) Pirke Abot, c. 4. sect. 1. (f) Paraen. ad Demos Orat. 1.

Honour all men--according to whatever honor is due in each case. Equals have a respect due to them. Christ has dignified our humanity by assuming it; therefore we should not dishonor, but be considerate to and honor our common humanity, even in the very humblest. The first "honor" is in the Greek aorist imperative, implying, "In every case render promptly every man's due" [ALFORD]. The second is in the present tense, implying, Habitually and continually honor the king. Thus the first is the general precept; the three following are its three great divisions.
Love--present: Habitually love with the special and congenial affection that you ought to feel to brethren, besides the general love to all men.
Fear God . . . the king--The king is to be honored; but God alone, in the highest sense, feared.

Honour all men - As being made in the image of God, bought by his Son, and designed for his kingdom. Honour the king - Pay him all that regard both in affection and action which the laws of God and man require.
