That the apostle might the better reach his end in writing this epistle, which is to make them steady and constant in a fiducial and practical remembrance of the doctrine of the gospel, he, 1. Expresses his special affection and tenderness for them, by calling them beloved, hereby evidencing that he added to godliness brotherly-kindness, as he had (Pe2 1:17) exhorted them to do. Ministers must be examples of love and affection, as well as life and conversation. 2. He evinces a sincere love to them, and hearty concern for them, by writing the same thing to them, though in other words. It being safe for them, it shall not be grievous to him to write upon the same subject, and pursue the same design, by those methods which are most likely to succeed. 3. The better to recommend the matter, he tells them that what he would have them to remember are, (1.) The words spoken by the holy prophets, who were divinely inspired, both enlightened and sanctified by the Holy Ghost; and, seeing these persons' minds were purified by the sanctifying operation of the same Spirit, they were the better disposed to receive and retain what came from God by the holy prophets. (2.) The commandments of the apostles of the Lord and Saviour; and therefore the disciples and servants of Christ ought to regard what those who are sent by him have declared unto them to be the will of their Lord. What God has spoken by the prophets of the Old Testament, and Christ has commanded by the apostles of the New, cannot but demand and deserve to be frequently remembered; and those who meditate on these things will feel the quickening virtues thereof. It is by these things the pure minds of Christians are to be stirred up, that they may be active and lively in the work of holiness, and zealous and unwearied in the way to heaven.

This second epistle - In order to guard them against the seductions of false teachers, he calls to their remembrance the doctrine of the ancient prophets, and the commands or instructions of the apostles, all founded on the same basis.

He possibly refers to the prophecies of Enoch, as mentioned by Jude, Jde 1:14, Jde 1:15; of David, Psa 1:1, etc.; and of Daniel, Dan 12:2, relative to the coming of our Lord to judgment: and he brings in the instructions of the apostles of Christ, by which they were directed how to prepare to meet their God.

This second epistle, beloved, I now write unto you,.... This is a transition to another part of the epistle; for the apostle having largely described false teachers, the secret enemies of the Christian religion under a profession of it, passes on to take notice of the more open adversaries and profane scoffers of it; and from their ridicule of the doctrine of Christ's second coming, he proceeds to treat of that, and of the destruction of the world, and the future happiness of the saints: he calls this epistle his "second epistle", because he had written another before to the same persons; and that the author of this epistle was an apostle, is evident from Pe2 3:2; and which, compared with Pe2 1:18 shows him to be the Apostle Peter, whose name it bears, and who was an eyewitness to the transfiguration of Christ on the mount, Mat 17:1, he addresses these saints here, as also in Pe2 3:8, under the character of "beloved"; because they were the beloved of God, being chosen by him according to his foreknowledge, and regenerated by him, according to his abundant mercy; and were openly his people, and had obtained mercy from him, and like precious faith with the apostles; and were also the beloved of Christ, being redeemed by him, not with gold and silver, but with his precious blood; for whom he suffered, and who were partakers of his sufferings, and the benefits arising from them, and who had all things given them by him, pertaining to life and godliness, and exceeding great and precious promises; and were likewise beloved by the apostle, though strangers, and not merely as Jews, or because they were his countrymen, but because they were the elect of God, the redeemed of Christ, and who were sanctified by the Spirit, and had the same kind of faith he himself had. The Syriac and Arabic versions read, "my beloved"; and the Ethiopic version, "my brethren": his end in writing both this and the former epistle follows;

in both which I stir up your pure minds by way of remembrance; that this was his view both in this and the former epistle, appears from Pe1 1:13; he calls their minds pure; not that they were so naturally, for the minds and consciences of men are universally defiled with sin; nor are the minds of all men pure who seem to be so in their own eyes, or appear so to others; nor can any man, by his own power or works, make himself pure from sin; only the blood of Christ purges and cleanses from it; and a pure mind is a mind sprinkled with that blood, and which receives the truth as it is in Jesus, in the power and purity of it, and that holds the mystery of the faith in a pure conscience. Some versions, as the Vulgate Latin and Arabic, render the word "sincere", as it is in Phi 1:10; and may design the sincerity of their hearts in the worship of God, in the doctrines of Christ, and to one another, and of the grace of the Spirit of God in them; as that their faith was unfeigned, their hope without hypocrisy, and their love without dissimulation, and their repentance real and genuine; but yet they needed to be stirred up by way of remembrance, both of the truth of the Gospel, and the duties of religion; for saints are apt to be forgetful of the word, both of its doctrines and its exhortations; and it is the business of the ministers of the word to put them in mind of them, either by preaching or by writing; and which shows the necessity and usefulness of the standing ministry of the Gospel: the particulars he put them in mind of next follow.
