Title:
Heresy

Context:
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." He stigmatizes Jewish Prayer as being "blasphemous" (sic) and a lie, and vilifies Jews in general as being spiritually "blind" and "surely possessed by all devils." Luther calls the members of the Orthodox Catholic Church "papists" and heretics, and has a special spiritual problem with Jewish circumcision.

Question:
What term does Luther assign to the practice of Jewish Prayer?

blasphemous
