Peter emphasizes once again that he is an eyewitness to Christ’s deeds and asks us to take particular account of the fact that his testimony about His teaching is not based on what others have told him, but on his own direct recollections. Peter bears witness to what he saw on the Mount of Transfiguration, about which Christ asked them not to speak “until the Son of Man is risen from the dead” (Matt. 17:9). We can hardly imagine how easy or difficult it was for Peter to keep such an astonishing event secret, but now the time has come to tell of it.
And here we see that the apostle places above his own testimony the prophetic word spoken several centuries earlier by those who did not live to see Christ’s coming. Personal experience as a witness might seem more important than something heard or read, but for Peter it matters that what he testifies to is an integral link in the unbroken chain of the one process of Revelation. In this process, what is new not only does not deny what was proclaimed before, but is confirmed by it and acknowledges everything that comes from God.
