This is why, and I hope this is clear, there is a DISTINCTION between Israel (the remnant of in the nation of) and the Gentiles. Paul speaks to this in Romans. When the word Gentile is used by Paul in his letter, he is speaking of non-Jewish Gentiles, because they are a race. Mixed race Jews are NOT a race, thus not ethnos. Again, David, Jesus ancestor, was mixed race, because his father was mixed race. (Ruth, the Moabitess, was King David's grandmother.) Jesus had several non-Jewish Gentiles in his family tree. He was still a Jew, and considered a Jew. Moses married a non-Jewish Gentile after he received the law. It didn't bother God one bit. It set off his brother and sister, but God dealt with that personally.God's prophets were prophets TO ISRAEL.
God's Word was given to Israel.
Jesus fulfilled the Law - especially the Ceremonial Law that instructed and commanded the high priest offer sacrifices yearly to atone - temporarily - the sins of the children of Israel under those Laws.
The high priest never left Israel to offer sacrifices for Gentiles. And Jesus as High Priest did not offer Himself for the sins of Gentiles. Gentiles were the enemy of God and of Israel. They were outside the covenants of God. The high priest sprinkled the Mercy Seat of the Hebrew Ark of the Covenant with the blood of the sacrifice and Jesus as High Priest was sent as Promised by God to the children of Israel to atone the sins of the children of Israel.
4 But when the fulness of the time was come, God sent forth his Son, made of a woman, made under the law,
5 To redeem them that were under the law, that we might receive the adoption of sons. Galatians 4:4–5.
There are NO GENTILES (non-Hebrews) that are mentioned in this passage by Saul. Saul was a rabbi and Pharisee and He knows that there are NO GENTILES in covenant with God.
NONE.
Stop adding to the Bible.
I'm not adding to the BIble, you are removing from the Bible. Paul is clear. Non-Hebrew Gentiles being a part of the body of Christ was a mystery. God did not reveal it in the Old Testament. He first revealed it to Peter, but it was Paul who ran with it. God revealed it to Peter so that the non-Jewish Gentiles could be added to the church. As Paul says in Galatians, Jesus destroyed the emnity that existed between the Jews and the Gentiles. (Ethnos... so not mixed race.) In Acts, in one city, it speaks of Jews, Greeks and Gentiles in Acts. So, was Luke talking about the same people? Of course not, and the passage is actually quite clear about it.
IF you continue to believe that it is the flesh that saves, and thus the covenants, you are doomed. The flesh, the law, does not save at all. The Spirit, faith, that saves. Covenants do not. And again, Jesus is the mediator of the New Covenant, as priest, but JEsus is not a priest of any line of Israel. He is priest in the line of Melchizedek. Abraham himself paid homage to Melchizedek. Abraham did not go to Melchizedek. Melchizedek came to Abraham. Melchizedek was NOT Hebrew or Jewish, but he, as a non-Hebrew Gentile, was the priest of the Almighty God. So why are you saying that Melchizedek was hell bound, for not being a part of any covenant with God?
