Actually, I've lately started to suspect that 1 Peter is genuine (as I do with the Letter of James). To me 1 Pet. 2:4-6 sounds similar to something in col. 8 of the Community Rule (and bearing in mind that it follows references in chapter 1 to the sufferings of the letter's recipients -who seem like Jews to me- and of Jesus)....everyone knows Simon Peter wrote the Qumran texts.
1QS col. 8:As you come to him, the living Stone—rejected by humans but chosen by God and precious to him— you also, like living stones, are being built into a spiritual house to be a holy priesthood, offering spiritual sacrifices acceptable to God through Jesus Christ. For in Scripture it says: “See, I lay a stone in Zion, a chosen and precious cornerstone, and the one who trusts in him will never be put to shame.”
In the Council of the Community there shall be twelve men and three Priests, perfectly versed in all that is revealed of the Law, whose works shall be truth, righteousness, justice, loving kindness, and humility. They shall preserve the faith in the Land with steadfastness and meekness and shall atone for sin by the practice of justice and by suffering the sorrows of affliction. They shall walk with all men according to the standard of truth and the rule of the time.
When these are in Israel, the Council of the Community shall be established in truth. It shall be an Everlasting Plantation, a House of Holiness for Israel, an Assembly of Supreme Holiness for Aaron. They shall be witnesses to the truth at the judgment, and shall be the elect of Goodwill who shall atone for the Land and pay to the wicked their reward. It shall be that tried wall, that precious corner-stone, whose foundations shall neither rock nor sway in their place.
It shall be a Most Holy Dwelling for Aaron, with everlasting knowledge of the Covenant of justice, and shall offer up sweet fragrance. It shall be a House of Perfection and Truth in Israel that they may establish a Covenant according to the everlasting precepts. And they shall be an agreeable offering, atoning for the Land and determining the judgment of wickedness, and there shall be no more iniquity.
When I first read 1 Peter it struck me as being exactly what I would write if I wanted to make up a letter that appears to be associated with the DSS. I had already thought that about the Letter of James, so it was curious, if nothing else, to look at 1 Peter (which I had previously neglected) in that light.
Another thing that stood out was 1 Pet. 1:5-11:
This reminds me of something from the Damascus Document regarding the coming of the Messiah in the last days (I can't tell what the column number is in the Vermes translation I'm using):...until the coming of the salvation that is ready to be revealed in the last time. In all this you greatly rejoice, though now for a little while you may have had to suffer grief in all kinds of trials. These have come so that the proven genuineness of your faith—of greater worth than gold, which perishes even though refined by fire—may result in praise, glory and honor when Jesus Christ is revealed. Though you have not seen him, you love him; and even though you do not see him now, you believe in him and are filled with an inexpressible and glorious joy, for you are receiving the end result of your faith, the salvation of your souls.
...a book of reminder shall be written before Him of them that fear God and worship His Name, against the time when salvation and righteousness shall be revealed to them that fear God ... they shall rejoice and their hearts shall be strong, and they shall prevail over all the sons of the earth. God will forgive them and they shall see His salvation [yeshua] because they took refuge in His holy Name.
