In Ancient Judaism, his fourth major work on the sociology of religion, Weber attempted to explain the factors that resulted in the early differences between Oriental and Occidental religiosity.[6] He contrasted the innerworldly asceticism developed by Western Christianity with mystical contemplation of the kind developed in India.[6] Weber noted that some aspects of Christianity sought to conquer and change the world, rather than withdraw from its imperfections.[6] This fundamental characteristic of Christianity (when compared to Far Eastern religions) stems originally from ancient Jewish prophecy.[7]
