Andreas of Caesarea : Peter repeats what he has already said about virtue and the commandments consequent on it, through which we shall enter the kingdom of heaven with great assurance. Notice how, when speaking of the kingdom of heaven, Peter first goes over the things we should be afraid of and then over the good things, ending up with the judgment seat. — CATENA Bede : Wherefore I will always begin to admonish you about these things, etc. Why does he want to always admonish them about good works, those whom he says have knowledge and are confirmed in the present truth? Unless perhaps it is so that the knowledge they have learned they may exercise in good works, and the truth of which they are confirmed in presence they may guard with a fixed mind, lest ever through teachers of error they fall from the simplicity and purity of faith, concerning which teachers he speaks more in the course of the Epistle. And this sentiment agrees with that of blessed John, who says: "I have not written to you because you do not know the truth, but because you do know it" (1 John 2). Therefore, the apostles write to those who know the truth, and admonish them so that they might observe what they know. Whence also John, speaking, adds shortly after: "Let that which you have heard from the beginning remain in you" (Ibid.). — Commentary on the Catholic Epistles Hilary of Arles : The people to whom Peter is writing already know what he has to say because they have read his first letter. The truth which he has to share with them is the New Testament, for as Paul said: "The old has passed away, and all things are made new in Christ." — INTRODUCTORY COMMENTARY ON 2 PETER Oecumenius : Therefore, I will not neglect to remind you always of these things, even though you know and are established in the present truth. "even though you know." So that they are not seen to be continually admonished about the same things, as if rebuked for living in idleness, and thus become saddened, for this reason Peter adds: even though you know and are established in the present truth. Moreover, giving a reason for the continuous admonition, he added that he knew a release from this body would soon come. — Commentary on 2 Peter
