I want to know the answer to the following question:
What is said to be a special spiritual problem?
All the background I'm provided with is that "In his work "On the Jews and Their Lies" (1543), German Reformation leader Martin Luther claims that Jewish history was "assailed by much heresy", and that Christ the logos swept away the Jewish heresy and goes on to do so, "as it still does daily before our eyes."". Is that enough to answer the question?
Answer: no
