1. Various churches have maintained various beliefs. I don't have any reading of Scofield or dispensationalism. Condemnation of "the Jews" is not doctrine of the Lutheran Church Missouri Synod, which preceded Scofield, and all you are doing is invoking an argument from authority, which is a notorious rhetorical fallacy. ("JudeoChristian values" is a reference to the Ten Commandments, if it refers to anything.)

2. It was not the "last chance" for all the Jews who came to Christ during the period following Christ's crucifixion. Nor is it ever. You talk as though Christ's crucifixion was not pre-known and expected, yet Jesus was at pains to predict that this would be exactly what happens. Without it, we would not have the demonstration of the New Testament in his blood and body.

It is not up to you to determine the fate of the Jews. It is up to each one of them. You have no hand in it. They are not yours to condemn. (And Luther's writings on the Jews are about the least recognized of his far more relevant works.)
