After having taught the faithful that they had been regenerated by the word of God, he now exhorts them to lead a life corresponding with their birth. For if we live in the Spirit, we ought also to walk in the Spirit, as Paul says. (Galatians 5:25.) It is not, then, sufficient for us to have been once called by the Lord, except we live as new creatures. This is the meaning. But as to the words, the Apostle continues the same metaphor. For as we have been born again, he requires from us a life like that of infants; by which he intimates that we are to put off the old man and his works. Hence this verse agrees with what Christ says,

“Except ye become like this little child,
ye shall not enter into the kingdom of God.”
(Matthew 18:3.)

Infancy is here set by Peter in opposition to the ancientness of the flesh, which leads to corruption; and under the word milk, he includes all the feelings of spiritual life. For there is also in part a contrast between the vices which he enumerates and the sincere milk of the word; as though he had said, “Malice and hypocrisy belong to those who are habituated to the corruptions of the world; they have imbibed these vices: what pertains to infancy is sincere simplicity, free from all guile. Men, when grown up, become imbued with envy, they learn to slander one another, they are taught the arts of mischief; in short, they become hardened in every kind of evil: infants, owing to their age, do not yet know what it is to envy, to do mischief, or the like things.” He then compares the vices, in which the oldness of the flesh indulges, to strong food; and milk is called that way of living suitable to innocent nature and simple infancy.

1. All malice There is not here a complete enumeration of all those things which we ought to lay aside; but when the Apostles speak of the old man, they lay down as examples some of those vices which mark his whole character.

“Known,” says Paul, “are the works of the flesh, which are these,” (Galatians 5:19;)

and yet he does not enumerate them all; but in those few things, as in a mirror, we may see that immense mass of filth which proceeds from our flesh. So also in other passages, where he refers to the new life, he touches only on a few things, by which we may understand the whole character.

What, then, he says amounts to this, — “Having laid aside the works of your former life, such as malice, deceit, dissimulations, envyings, and other things of this kind, devote yourselves to things of an opposite character, cultivate kindness, honesty,” etc. He, in short, urges this, that new morals ought to follow a new life.

2. The sincere milk of the word This passage is commonly explained according to the rendering of Erasmus, “Milk not for the body but for the soul;” as though the Apostle reminded us by this expression that he spoke metaphorically. I rather think that this passage agrees with that saying of Paul,

“Be ye not children in understanding, but in malice.”
(1 Corinthians 14:20.)

That no one might think that infancy, void of understanding and full of fatuity, was commended by him, he in due time meets this objection; so he bids them to desire milk free from guile, and yet mixed with right understanding. We now see for what purpose he joins these two words, rational and guileless, (λογικὸν καὶ ἄδολος.) For simplicity and quickness of understanding are two things apparently opposite; but they ought to be mixed together, lest simplicity should become insipid, and lest malicious craftiness should creep in for want of understanding. This mingling, well regulated, is according, to what Christ says,

“Be ye wise as serpents, and harmless as doves.”
(Matthew 10:16.)

And thus is solved the question which might have been otherwise raised. ¹⁹¹⁹     Our version here seems to convey the most suitable meaning, by taking λογικὸν for τοῦ λόγου; see similar instances in ver. 13 and 1 Peter 3:7. It is the wordy milk, or milk made up of the word; the word is the milk. Then ἄδολον is to be taken in its secondary meaning: when applied to persons, it means undeceitful, or guileless; but when to things, genuine, pure, unadulterated, unmixed with anything deleterious. We may, therefore, render the words, “Desire the pure milk of the word.” It is a milk not adulterated by water or by anything poisonous. There is no contrast here between milk and strong food; but it includes all that is necessary as an aliment for the soul, when renewed. The Word had before been represented as the instrument of the new birth; it is now spoken of as the food and aliment of the new-born. — Ed.

Paul reproves the Corinthians because they were like children, and therefore they could not take strong food, but were fed with milk. (1 Corinthians 3:1.) Almost the same words are found in Hebrews 5:12. But in these passages those are compared to children who remain always novices and ignorant scholars in the doctrine of religion, who continued in the first elements, and never penetrated into the higher knowledge of God. Milk is called the simpler mode of teaching, and one suitable to children, when there is no progress made beyond the first rudiments. Justly, then, does Paul charge this as a fault, as well as the author of the Epistle to the Hebrews. But milk, here, is not elementary doctrine, which one perpetually learns; and never comes to the knowledge of the truth, but a mode of living which has the savor of the new birth, when we surrender ourselves to be brought up by God. In the same manner infancy is not set in opposition to manhood, or full age in Christ, as Paul calls it in Ephesians 4:13, but to the ancientness of the flesh and of former life. Moreover, as the infancy of the new life is perpetual, so Peter recommends milk as a perpetual aliment, for he would have those nourished by it to grow.

3 If so be that ye have tasted; or, If indeed ye have tasted. He alludes to Psalm 34:8,

“Taste and see that the Lord is good.”

But he says that this taste is to be had in Christ, as, doubtless, our souls can find no rest anywhere but in him. But he has drawn the ground of his exhortation from the goodness of God, because his kindness, which we perceive in Christ, ought to allure us; for what follows,

To whom coming, is not to be referred simply to God, but to him as he is revealed to us in the person of Christ. Now, it cannot be but that the grace of God must powerfully draw us to himself and inflame us with the love of him by whom we obtain a real perception of it. If Plato affirmed this of his Beautiful, of which a shadowy idea only he beheld afar off, much more true is this with regard to God.

Let it then be noticed, that Peter connects an access to God with the taste of his goodness. For as the human mind necessarily dreads and shuns God, as long as it regards him as rigid and severe; so, as soon as he makes known his paternal love to the faithful, it immediately follows that they disregard all things and even forget themselves and hasten to him. In short, he only makes progress in the Gospel, who in heart comes to God.

But he also shews for what end and to what purpose we ought to come to Christ, even that we may have him as our foundation. For since he is constituted a stone, he ought to be so to us, so that nothing should be appointed for him by the Father in vain or to no purpose. But he obviates an offense when he allows that Christ is rejected by men; for, as a great part of the world reject him, and even many abhor him, he might for this reason be despised by us; for we see that some of the ignorant are alienated from the Gospel, because it is not everywhere popular, nor does it conciliate favor to its professors. But Peter forbids us to esteem Christ the less, however despised he may be by the world, because he, notwithstanding, retains his own worth and honor before God.

5. Ye also, as lively or living stones, are built up The verb may be in the imperative as well as in the indicative mood, for the termination in Greek is ambiguous. But in whatever way it is taken, Peter no doubt meant to exhort the faithful to consecrate themselves as a spiritual temple to God; for he aptly infers from the design of our calling what our duty is. We must further observe, that he constructs one house from the whole number of the faithful. For though every one of us is said to be the temple of God, yet all are united together in one, and must be joined together by mutual love, so that one temple may be made of us all. Then, as it is true that each one is a temple in which God dwells by his Spirit, so all ought to be so fitted together, that they may form one universal temple. This is the case when every one, content with his own measure, keeps himself within the limits of his own duty; all have, however, something to do with regard to others.

By calling us living stones and spiritual building, as he had before said that Christ is a living stone, he intimates a comparison between us and the ancient temple; and this serves to amplify divine grace. For the same purpose is what he adds as to spiritual sacrifices For by how much the more excellent is the reality than the types, by so much the more all things excel in the kingdom of Christ; for we have that heavenly exemplar, to which the ancient sanctuary was conformable, and everything instituted by Moses under the Law.

A holy priesthood It is a singular honor, that God should not only consecrate us as a temple to himself, in which he dwells and is worshipped, but that he should also make us priests. But Peter mentions this double honor, in order to stimulate us more effectually to serve and worship God. Of the spiritual sacrifices, the first is the offering of ourselves, of which Paul speaks in Romans 12:1; for we can offer nothing, until we offer to him ourselves as a sacrifice; which is done by denying ourselves. Then, afterwards follow prayers, thanksgiving, almsdeeds, and all the duties of religion.

Acceptable to God. It ought also to add not a little to our alacrity, when we know that the worship we perform to God is pleasing to him, as doubt necessarily brings sloth with it. Here, then, is the third thing that enforces the exhortation; for he declares that what is required is acceptable to God, lest fear should make us slothful. Idolaters are indeed under the influence of great fervor in their fictitious forms of worship; but it is so, because Satan inebriates their minds, lest they should come to consider their works; but whenever their consciences are led to examine things, they begin to stagger. It is, indeed, certain that no one will seriously and from the heart devote himself to God, until he is fully persuaded that he shall not labor in vain.

But the Apostle adds, through Jesus Christ There is never found in our sacrifices such purity, that they are of themselves acceptable to God; our self-denial is never entire and complete, our prayers are never so sincere as they ought to be, we are never so zealous and so diligent in doing good, but that our works are imperfect, and mingled with many vices. Nevertheless, Christ procures favor for them. Then Peter here obviates that want of faith which we may have respecting the acceptableness of our works, when he says, that they are accepted, not for the merit of their own excellency, but through Christ. And it ought to kindle the more the ardor of our efforts, when we hear that God deals so indulgently with us, that in Christ he sets a value on our works, which in themselves deserve nothing. At the same time, the words, by or through Christ, may be fitly connected with offering; for a similar phrase is found in Hebrews 13:15,

“Through him let us offer the sacrifice of praise to God.”

The sense, however, will remain the same; for we offer sacrifices through Christ, that they may be acceptable to God.
