Paul teaches what is now called replacement theology. There is a reason the church has taught this doctrine for two thousand years. Paul teaches that all acceptance by God comes through belief in Jesus. Jews and gentiles that believe in Jesus are accepted all others are cut off.
Paul teaches that a man is not a Jew if he is only outwardly a Jew (Rom 2:28, 29). He says that all, Jews and gentiles, that have the faith of Abraham are the children of Abraham (Gal. 3:7).
Jesus told some faithless Jews who thought that God was their father that, actually, the Devil was their father (John 8:42-47).
Paul says that unbelieving Jews were cut off and that believing gentiles were grafted into their place, that could be called replacement (Rom 11:17). Paul taught it.
Now believing Jews and gentiles are one in Christ. God accepts people only on the basis of faith not on the basis of birth.
As to Luther, in his old age he reacted wrongly to blasphemy in the Talmud. He was not anti-Semitic (that is an idea based in racism which Luther did not hold), Luther based his anger against the Jews on the anti-Christian writings in the Talmud not on their race. In fact, like Paul, Luther disagreed with the Jews on their pride of blood descent. (Hitler based his hatred of Jews on blood not on their beliefs.)
Paul says that not only did the Jews kill Jesus and their own prophets, but that they were continuing to persecute the Christians. For that Paul says the wrath of God has come upon them (Thes. 2:15-16). Jewish persecution and blasphemy was recorded in the Talmud, and Luther reacted to it.
Paul says that gentiles that are no longer to be looked down upon by Jews as “uncircumcised.” Through Christ, we are now “citizens of Israel” Eph. 2:11-12). That is why Christians took on the “mantle of Israel”, because God gave it to us though the work of Christ.
Oh never mind.
Hal Lindsey and Whisenut predicted that Christ was coming back by 1988 based on their faulty views of the need for Israel to be reestablished.
Tim LaHaye wrote that the generation which saw WW1 would see the second coming. He has also moved to the unbiblical idea that the generation that was around in 1948 or 1967 will see the return.
Camping’s errors were not based on replacement theology. He’s just a Kook. Christians, Jewish and gentile, are the chosen people through faith.
Lindsey’s pro-Israel view led to his error (Late Great).
