1 Peter 3:4

But let it be the hidden person of the heart, in the incorruptibility of a quiet and meek spirit, etc. He preaches chastity and the adornment of the inner man in the incorruption of a quiet and meek spirit, saying almost: Since your outer person …

For: "All the glory of the King's daughter is within; her garments are trimmed with gold, embroidered" (Ps. 44:14). That is, our hidden disposition and outward condition must correspond exactly to one another. The trimming with gold signifies outward activity. And he calls the garments …

"I do not regard these things," is often said by those whose hearts are wrapped up in them: but offer to take them away, and you touch the very idol of their soul. Some, indeed only dress elegantly that they may be looked on; that is, they squander away their Lord's talent to gain applause: thus making sin to beget sin, and then plead one in excuse of the other.

Secondly, The ornament prescribed. It must, in general, be something not corruptible, that beautifies the soul, that is, the graces and virtues of God's Holy Spirit. The ornaments of the body are destroyed by the moth, and perish in the using; but the grace of God, the longer we wear it, the brighter and better it is.

But let it be the hidden man of the heart,....

He exhorts Christians to unity, love, compassion, peace, and patience under sufferings; to oppose the slanders of their enemies, not by returning evil for evil, or railing for railing, but by blessing; by a ready account of their faith and hope, and by keeping a good conscience,

The hidden man of the heart - Ὁ κρυπτος της καρδιας ανθρωπος. This phrase is of the same import with that of St. Paul, Rom 7:22, ὁ εσω ανθρωπος, the inner man; that is, the soul, with the whole system of affections and passions. Every part of the Scripture treats man as a compound being: the body is the outward or visible man; the soul, the inward, hidden, or invisible man. The term ανθρωπος, man, is derived, according to the best etymologists, from ανα τρεπων ωπα, turning the face upward. This derivation of the word is beautifully paraphrased by Ovid.

Under costly attire there may be a humble mind. "Great is he who uses his earthenware as if it were plate; not less great is he who uses his silver as if it were earthenware" [SENECA in ALFORD]. hidden--inner man, which the Christian instinctively hides from public view. of the heart--consisting in the heart regenerated and adorned by the Spirit.

But let it be the hidden man of the heart - This expression is substantially the same as that of Paul in Rom 7:22, “the inward man.” See the notes at that place. The word “hidden” here means that which is concealed; that which is not made apparent by the dress, or by ornament. It lies within, pertaining to the affections of the soul. In that which is not corruptible - Properly, “in the incorruptible ornament of a meek and quiet spirit.” This is said to be incorruptible in contradistinction to gold and apparel. They will decay; but the internal ornament is ever enduring. The sense is, that whatever pertains to outward decoration, however beautiful and costly, is fading; but that which pertains to the soul is enduring. As the soul is immortal, so all that tends to adorn that will be immortal too; as the body is mortal, so all with which it can be invested is decaying, and will soon be destroyed. The ornament of a meek and quiet spirit - Of a calm temper; a contented mind; a heart free from passion, pride, envy, and irritability; a soul not subject to the agitations and vexations of those who live for fashion, and who seek to be distinguished for external adorning. The connection here shows that the apostle refers to this, not only as that which would be of great price in the sight of God, but as that which would tend to secure the affection of their husbands, and win them to embrace the true religion, (see 1Pe 3:1-2); and, in order to this, he recommends them, instead of seeking external ornaments, to seek those of the mind and of the heart, as more agreeable to their husbands; as better adapted to win their hearts to religion; as that which would be most permanently proved.
