From Clement of Alexandria, Miscellanies 6.15: Now all the prophets who foretold the advent of the Lord and with it the holy mysteries accompanying it were persecuted and killed. As also the Lord himself, in explaining the scriptures to them, and his disciples who preached the word like him, and subsequently to his life used parables. Whence also Peter in his preaching, speaking of the apostles, says: "But we, unrolling the books of the prophets which we possess, who name Jesus Christ partly in parables, partly in enigmas, partly expressly and in so many words, find his advent and death, and cross, and all the rest of the tortures which the Jews inflicted on him, and his resurrection and taking up into heaven previous to the capture/foundation of Jerusalem, thus written. These are all the things that he must suffer, and what should be after him. Recognizing them, therefore, we have believed in God in consequence of what is written respecting him." And after a little again he draws the inference that the scriptures owed their origin to the divine providence, asserting as follows: "For we know that God enjoined these things, and we say nothing apart from the scriptures."
Is there anything to the fact that these similar statements are both attributed to Peter? Are there other statements like this attributed to him somewhere? What other statements are there like this, period?
