Read this: Although Albertus Magnus did much to instill mysticism in the Order of Preachers, it is a concept that reaches back to the Hebrew Bible. In the tradition of Holy Writ, the impossibility of coming face to face with God is a recurring motif, thus the commandment against graven images (Exodus 20.4-5). As time passed, Jewish and early Christian writings presented the idea of 'unknowing,' where God's presence was enveloped in a dark cloud. These images arose out of a confusing mass of ambiguous and ambivalent statements regarding the nature of God and man's relationship to Him.
