Entdecktes Judenthum is the most malignant attack that Judaism has ever sustained. --Rev. Isidore Harris --The Thinker: A Review of Worldwide Christian Thought, p. 498.
Fate decreed that a certain Christian writer, Johann Andreas Eisenmenger, should have arisen...and concentrated the tradition of medieval anti-Jewish doctrines in his great work...His book was impressive on account of its size...and its tremendous erudition. Eisenmenger was well-versed in Hebrew, Aramaic and Arabic...In short, Eisenmenger was acquainted with all the literature a Jewish scholar of standing would have known. He had learned to use these books partly through contacts with Jewish scholars in Frankfort and Amsterdam...However, Eisenmenger surpassed his predecessors in his mastery of the sources and his ability to interpret them...Jacob Katz, From Prejudice to Destruction: Anti-Semitism, 1700-1933
Christian scholars used their immense, sometimes phenomenal learning to warn their brethren about the rising Jewish peril...as a whole, Wagenseil's collection was not comparable to the revelations in the volumes of Johann Andreas Eisenmenger...one of the most persistent gatherers of anti-Christian texts... --Frank Manuel --The Broken Staff: Judaism Through Christian Eyes
