The Gentiles
The expression “those who are far away” as Peter was saying, is found in the prayer of Solomon in 1Kings8:41-43. Here is referred to the stranger “who is not from the people Israel”. This are the gentiles were Solomon is praying for, saying: “hear Thou in heaven Thy dwelling-place, and do according to all that the stranger calleth to Thee for; that all the peoples of the earth may know Thy name, to fear Thee, as doth Thy people Israel, and that they may know that Thy name is called upon this house which I have built.” (1Kings8:43). Those are coming “for thy Name’s sake” gentiles who fear God, who have a burden to know God and joined Israel. They have a place, even in the holy temple, to worship with the people of Israel and pray with them. There’s nothing here what implies that the gentile must convert himself. They are allowed, but not obligated. What we see here are God-fearing gentiles who join Israel.
A very good article about being a gentile with respect to the Jews, is to find here. It argues that it is great to be a gentile and to be like the Master and Lord Jesus, in His love and passion to one another’s brother.
The boundary marker for being incorporated into the people of God is faith in Christ rather than the works of the Law. According to Paul in Galatians.
So far we see two distinctions:
Distinction 1: Righteous (divine calling and rebirth, whether Jew or Gentile) or not (Pagans, wicked people, but also fake.)
Distinction 2: Jew or Gentile (the covenant issue.) There’s a covenantal relationship with Israel. But there are more covenantal relationships. The church also teaches such relationship were infant-baptism is a part of.
The first distinction is most important. That’s the question if one is righteous or not. That line cuts right through Jew and gentile alike. And divides genuine and fake. This is a matter of salvation or not.
There’s much to say about it, but I will stress the one and only important thing: especially after the time the Holy Spirit was poured out because of the fulfilled work of the Messiah Jesus, immediately repented people received a new born being, a new spirit, a new will, a new attraction to serve God in the most possible holy way they can achieve. That makes the most important difference. That makes whether you belong to the people of God, the sons of God, no matter if you are a gentile or Jew, an American or a Russian.
What I will argue here is that a gentile will fit conveniently in the Jewish commonwealth. There has always been a place for them. The Torah never rules out a gentile, but rather punish a sinner. The most basic rules for everyone are the 7 Noachide laws.
