Romans 9:24-25 “not from the Judahites only, but also from the Gentiles”? As he says also in Hosea, “I will call them ‘my people,’ which were not my people; and her ‘beloved,’ who was not beloved.”
Who are these Gentiles? Verse 25 gives the context sending us to Hosea. The Gentiles in verse 25 are those of ten tribed Israel who were divorced by God, Jeremiah 3:8. They were put away and punished, Matthew 15:24. They lost the right to be called Israel. If that had been the end of the house of Israel, Yahweh God would have been a promise breaker. That was not the end though. They were promised to be “sons of the living God” or Christians.
Hosea 1:10 “Yet the number of the children of Israel will be as the sand of the sea, which can’t be measured or counted; and it will come to pass that, in the place where it was said to them, ‘You are not my people,’ they will be called ‘sons of the living God.”
Matthew 15:24 But he answered, “I wasn’t sent to anyone but the put away and punished sheep of the house of Israel.”
These people are identified today as the Anglo-Saxon, Celtic, Germanic, Scandinavian and kindred peoples. I am aware of the claims of other groups, but they lack the evidence of history and archeology. They also lack the marks given by Scripture. The majority of these Israelites have been Christians through the centuries.
