"Judaism and Christianity, with all their contrasts and antagonisms, share in a common heritage: in vital parts of Jewish ideology and ethics, Jewish holy books, and the Jewish soil as an unforgotten homeland. Only with the de-nationalization of this heritage, with its spreading to the Ephesians, Thessalonians, and the Corinthians, so many alien ideas changed the original kernel that as actual separation was inevitable. But however far the two religions drifted apart in their tenets, a sacred bridge still spans the abyss and allows for an exchange of views and moral concepts and, with them, of liturgical forms in which the dogmas and concepts find their way to the senses." - Foreword.
