Wherein they think it strange The words of Peter literally are these, "In which they are strangers, you not running with them into the same excess of riot, blaspheming." But the word, to be strangers, means to stop at a thing as new and unusual. This is a way of speaking which the Latins also sometimes use, as when Cicero says that he was a stranger in the city, because he knew not what was carried on there. But in this place, Peter fortifies the faithful, lest they should suffer themselves to be disturbed or corrupted by the perverse judgments or words of the ungodly. For it is no light temptation, when they among whom we live, charge us that our life is different from that of mankind in general. "These," they say, "must form for themselves a new world, for they differ from all mankind." Thus they accuse the children of God, as though they attempted a separation from the whole world. Then the Apostle anticipated this, and forbade the faithful to be discouraged by such reproaches and calumnies; and he proposed to them, as a support, the judgment of God: for this it is that can sustain us against all assaults, that is, when we patiently wait for that day, in which Christ will punish all those who now presumptuously condemn us, and will shew that we and our cause are approved by Him. And he expressly mentions the living and the dead, lest we should think that we shall suffer any loss, if they remain alive when we are dead; for they shall not, for this reason, escape the hand of God. And in what sense he calls them the living and the dead, we may learn from the fifteenth chapter of the first Epistle to the Corinthians

Wherein they think it strange - In respect to which vices, they who were once your partners and accomplices now think it strange that you no longer unite with them. They do not understand the reasons why you have left them. They regard you as abandoning a course of life which has much to attract and to make life merry, for a severe and gloomy superstition. This is a true account of the feelings which the people of the world have when their companions and friends leave them and become Christians. It is to them a strange and unaccountable thing, that they give up the pleasures of the world for a course of life which to them seems to promise anything but happiness. Even the kindred of the Saviour regarded him as" beside himself," Mark 3:21, and Festus supposed that Paul was mad, Acts 26:24. There is almost nothing which the people of the world so little comprehend as the reasons which influence those with ample means of worldly enjoyment to leave the circles of gaiety and vanity, and to give themselves to the serious employments of religion. The epithets of fool, enthusiast, fanatic, are terms which frequently occur to the heart to denote this, if they are not always allowed to escape from the lips. The reasons why they esteem this so strange, are something like the following:
(1) They do not appreciate the motives which influence those who leave them. They feel that it is proper to enjoy the world, and to make life cheerful, and they do not understand what it is to act under a deep sense of responsibility to God, and with reference to eternity. They live for themselves. They seek happiness as the end and aim of life. They have never been accustomed to direct the mind onward to another world, and to the account which they must soon render at the bar of God. Unaccustomed to act from any higher motives than those which pertain to the present world, they cannot appreciate the conduct of those who begin to live and act for eternity.
(2) they do not yet see the guilt and folly of sinful pleasures. They are not convinced of the deep sinfulness of the human soul, and they think it strange that ethers should abandon a course of life which seems to them so innocent. They do not see why those who have been so long accustomed to these indulgences should have changed their opinions, and why they now regard those tilings as sinful which they once considered to be harmless.
(3) they do not see the force of the argument for religion. Not having the views of the unspeakable importance of religious truth and duty which Christians now have, they wonder that they should break off from the course of life which they formerly pursued, and separate from the mass of their fellow-men. Hence, they sometimes regard the conduct of Christians as amiable weakness; sometimes as superstition; sometimes as sheer folly; sometimes as madness; and sometimes as sourness and misanthropy. In all respects they esteem it strange:
"Lions and beasts of savage name.
Put on the nature of the lamb,
While the wide world esteems it strange,
Gaze, and admire, and hate the change."
That ye run not with them - There may be an allusion here to the well-known orgies of Bacchus, in which his votaries ran as if excited by the furies, and were urged on as if transported with madness. See Ovid, Metam. iii. 529, thus translated by Addison:
"For now, through prostrate Greece, young Bacchus rode,
Whilst howling matrons celebrate the god;
All ranks and sexes to his orgies ran,
To mingle in the pomp and fill the train,"
The language, however, will well describe revels of any sort, and at any period of the world.
To the same excess of riot - The word rendered "excess" (ἀνάχυσις anachusis) means, properly, a pouring out, an affusion; and the idea here is, that all the sources and forms of riot and disorder were poured out together. There was no withholding, no restraint. The most unlimited indulgence was given to the passions. This was the case in the disorder referred to among the ancients, as it is the case now in scenes of midnight revelry. On the meaning of the word riot, see the Ephesians 5:18 note; Titus 1:6 note.
Speaking evil of you - Greek, blaspheming. See the notes at Matthew 9:3. The meaning here is, that they used harsh and reproachful epithets of those who would not unite with them in their revelry. They called them fools, fanatics, hypocrites, etc. The idea is not that they blasphemed God, or that they charged Christians with crime, but that they used language suited to injure the feelings, the character, the reputation of those who would no longer unite with them in the ways of vice and folly.

They think it strange - Ξενιζονται· They wonder and are astonished at you, that ye can renounce these gratifications of the flesh for a spiritual something, the good of which they cannot see.
Excess of riot - Ασωτιας αναχυσιν· Flood of profligacy; bearing down all rule, order, and restraints before it.
Speaking evil of you - Βλασφημουντες· Literally, blaspheming; i.e. speaking impiously against God, and calumniously of you.

(3) Wherein they think it (c) strange that ye run not with [them] to the same excess of riot, speaking evil of [you]:
(3) That we be not moved with the enemies perverse and slanderous judgments of us, we have to set against them that last judgment of God which remains for them: for none, whether they be then found living or were dead before, shall escape it.
(c) They think it a new and strange matter.

Wherein they think it strange,.... Here the apostle points out what the saints must expect from the men of the world, by living a different life; and he chooses to mention it, to prevent discouragements, and that they might not be uneasy and distressed when they observed it; as that they would wonder at the change in their conversations, and look on it as something unusual, new, and unheard of, and treat them as strangers, yea, as enemies, on account of it:
that you run not with them into the same excess of riot; to their luxurious entertainments, their Bacchanalian feasts, and that profusion of lasciviousness, luxury, intemperance, and wickedness of all sorts, which, with so much eagerness of mind, and bodily haste, they rushed into; being amazed that they should not have the same taste for these things as before, and as themselves now had; and wondering how it was possible for them to abstain from them, and what that should be that should give them a different cast of mind, and turn of action:
speaking evil of you; and so the Syriac and Arabic versions supply "you" as we do; but in the Greek text it is only, "speaking evil of, or blaspheming"; God, Christ, religion, the Gospel, and the truths of it, and all good men; hating them because different from them, and because their lives reprove and condemn them; charging them with incivility, unsociableness, preciseness, and hypocrisy.

Wherein--In respect to which abandonment of your former walk (1-Peter 4:3).
run not with them--eagerly, in troops [BENGEL].
excess--literally, "profusion"; a sink: stagnant water remaining after an inundation.
riot--profligacy.
speaking evil--charging you with pride, singularity, hypocrisy, and secret crimes (1-Peter 4:14; 2-Peter 2:2). However, there is no "of you" in the Greek, but simply "blaspheming." It seems to me always to be used, either directly or indirectly, in the sense of impious reviling against God, Christ, or the Holy Spirit, and the Christian religion, not merely against men as such; Greek, 1-Peter 4:14, below.

The same - As ye did once. Speaking evil of you - As proud, singular, silly, wicked and the like.
