 He further acted as the apologist of Judaism in a pamphlet against Lagarde ("Prof. Paul de Lagarde, nach Seiner Natur Gezeichnet", 1887), who denounced all Jewish scholars as dilettanti; and when the blood accusation was revived, he republished (1888) the opinion of Cardinal Ganganelli—afterward Pope Clement XIV—to prove the falsity of this charge.While orthodox in his religious views, Berliner was never a fanatic.He not only associated in his scientific work with the liberals, but also paid a high tribute to the merits of Moritz Steinschneider, on the occasion of the latter's seventieth birthday (1886), by compiling a bibliography of that eminent scholar's works.
