The REAL "replacement Theology" replaces the Faithful Servants with the unfaithful servants as the true Heirs.
Such is OPPOSITE to scriptural teaching.
In Elijah's era, the multitude of Israelites who worshiped the false god Baal was so great that faithful Israel narrowed
to a mere seven thousand men (
1 Kings 19:1-18; Rom 11:2-4) and the rest were excommunicated out of the Covenant forever.
That faithful remnant at that time constituted ALL Israel, and from that time forward ONLY the descendants of those 7000 were Gods Covenanted Israel. The rest, again, were cut off forever.
That's how God preserves His remnant in times of Great Apostasy.
Scripture records numerous apostasies by--
and subsequent excommunications of--seditious sons of Abraham, while a faithful remnant remained ... and through the remnant and the remnant alone, "All Israel" Carried on...
Examples may be multiplied: God struck down thousands of rebellious Israelites in the wilderness (Num 14:26-45; Num 21:5-9; Num 16:1-50), though
the church was preserved and led to the Promised Land (
Acts 7:38-45); In Isaiah's day, apostasy became so rampant that "All Israel" continued to exist through a small but faithful remnant (Isa 10:22-23; Isa 1:7-9; Rom 9:27-29); And again as mentioned above, in Elijah's era, the multitude of Israelites who worshiped the false god Baal was so great that "All Israel" narrowed to a mere seven thousand men (
1 Kings 19:1-18; Rom 11:2-4). Lastly, at the close of the Old Testamental age, Israel was again reduced to a small remnant of faithful elect ones (Rom 11:5). The Jewish Pharisees and temple rulers grew wicked to the point of killing God's holy Messiah and apostles (1 Thess 2:14-16), and throngs wanted Caesar as king instead of Messiah, the son of David (Jn 19:15). Then, as in times past, "
All Israel" survived and continued on EXCLUSIVELY through the faithful sons, the Nazarene Sect (The REMNANT), while the unfaithful apostates were "cut off" from among the people FOREVER.
Just as the
jewish church abode with Moses in the wilderness (Acts 7:37-38), so Jesus had
HIS jewish church (Mt. 16:18-19).
St. Paul said that when the nation was in mass apostasy, the TRUE NATIONAL Israel was carried on not through the lineages of the wicked sons but rather through the OBEDIENT FEW (called the "remnant"), such as was true in Isaiah's day (
Romans 9:27-29) and Elijah's day (
Romans 11:3-5).
St. Peter says the same thing at Acts 3:22-24, where it is clear that the wicked jews who refuse Christ were to be "cut off from among the People of Israel" while the faithful jews (John the Baptist, Joseph and Mary, the Twelve, the Seventy, the three thousand on Pentecost day, and many thousands of other jews) were the True Faithful Israel.
And within a few years after Pentecost, the faithful Israel learned how to start accepting both jewish
and also gentile followers from all over the empire to convert into their Nation (
1 Peter 2:9-10; Mt 21:40-45). And so the tiny remnant True Israel grew into a worldwide Judaism living under the promised NEW covenant of Israel's Messiah.
And so it was also in Moses' day, when the countless thousands of wicked sons of Abraham were slain in the wilderness while the faithful sons of Abraham survived and got to enter the Promised Land.
We must NEVER count the continuation of Israel through the wicked sons but rather always through the faithful remnant!
Israel survived *exclusively* in the sect of the Nazarenes. They received with joy their promised New Covenant and obediently rejected all former biases against the non-Abrahamic families of earth so that Genesis 12:3 might finally be attained (Gal 3:7-9/Rom 4:13-18)---via the work of the Jewish Messiah. This sole surviving form of covenant Judaism is known worldwide as Christianity, the Jewish church gone global.
The church always was the covenanted Israel, the church continues to be the covenanted Israel. The only difference is that the NEW covenant of Israel enabled Jewish fullness to be bestowed upon gentile people groups (Gen 12:3).
The REAL "replacement theology" is the one who seeks to REPLACE the Faithful Sons of Abraham with the Wicked ones as the true Heirs.
Such is, sadly, RAMPANT here on CF.
