We'll just have to disagree. I believe 1 Peter is clearly to the nation of Israel. During Christ's earthly ministry, that generation was a generation of vipers, an untoward generation. But at the return of the Jewish Messiah, it will be for a chosen generation.
Peter, an apostle of Jesus Christ,
To the pilgrims of the Dispersion in Pontus, Galatia, Cappadocia, Asia, and Bithynia,
elect according to the foreknowledge of God the Father, in sanctification of the Spirit, for obedience and sprinkling of the blood of Jesus Christ:
Grace to you and peace be multiplied.
Blessed be the God and Father of our Lord Jesus Christ, who according to His abundant mercy has begotten us again to a living hope through the resurrection of Jesus Christ from the dead, to an inheritance incorruptible and undefiled and that does not fade away, reserved in heaven for you, who are kept by the power of God through faith for salvation ready to be revealed in the last time.
This is written to
the elect of God =
the Body of Christ.
Not to Jews according to the flesh.
Coming to Him
as to a living stone, rejected indeed by men, but chosen by God
and precious,
you also, as living stones, are being built up a spiritual house, a holy priesthood, to offer up spiritual sacrifices acceptable to God through Jesus Christ. Therefore it is also contained in the Scripture,
Do not tresspass against the Scripture as the serpent did in the Garden.
Any move to separate Jew from Gentile in Christ is sin and antichrist.
LISTEN to the APOSTLE PETER
Now the apostles and elders came together to consider this matter.
7And when there had been much dispute,
Peter rose up and said to them: “Men
and brethren, you know that a good while ago God chose among us, that by my mouth the Gentiles should hear the word of the gospel and believe.
8So God, who knows the heart,
[a]acknowledged them by giving them the Holy Spirit, just as
He did to us,
9and made no distinction between us and them, purifying their hearts by faith.
10Now therefore, why do you test God by putting a yoke on the neck of the disciples which neither our fathers nor we were able to bear?
11But we believe that through the grace of the Lord Jesus
Christ we shall be saved in the same manner as they.”
12Then all the multitude kept silent and listened to Barnabas and Paul declaring how many miracles and wonders God had worked through them among the Gentiles.
13And after they had become silent, James answered, saying, “Men
and brethren, listen to me:
14Simon has declared how God at the first visited the Gentiles to take out of them a people for His name.
15And with this the words of the prophets agree, just as it is written:
16‘After this I will return
And will rebuild the tabernacle of David, which has fallen down;
I will rebuild its ruins,
And I will set it up;
17So that the rest of mankind may seek the Lord,
Even all the Gentiles who are called by My name,
Says the Lord who does all these things.’
LISTEN to GOD
Praise the Lord!
For
it is good to sing praises to our God;
For
it is pleasant,
and praise is beautiful.
2The Lord builds up Jerusalem;
He gathers together the outcasts of Israel.
3He heals the brokenhearted
And binds up their wounds.
4He counts the number of the stars;
He calls them all by name.
5Great
is our Lord, and mighty in power;
His understanding
is infinite.
6The Lord lifts up the humble;
He casts the wicked down to the ground.
LISTEN TO PAUL
I tell the truth in Christ, I am not lying, my conscience also bearing me witness in the Holy Spirit,
2that I have great sorrow and continual grief in my heart.
3For I could wish that I myself were accursed from Christ for my brethren, my countrymen according to the flesh,
4who are Israelites, to whom
pertain the adoption, the glory, the covenants, the giving of the law, the service
of God, and the promises;
5of whom
are the fathers and from whom, according to the flesh, Christ
came, who is over all,
the eternally blessed God. Amen.
6But it is not that the word of God has taken no effect.
For they are not all Israel who are of Israel, 7nor are they all children because they are the seed of Abraham; but, “In Isaac your seed shall be called.” 8That is, those who are the children of the flesh, these are not the children of God; but the children of the promise are counted as the seed. 9For this
is the word of promise: “At this time I will come and Sarah shall have a son.”
