Messianic Judaism is a belief system that has assumed many different forms. Much like Protestantism, there are various sub-genres of a central core belief. The main characterization of Messianic Judaism as will be defined here is that there was a divine personage who fulfilled the role of the Messiah and whose name is YHSVH. Through belief that this sacrifice was the perfect and final sacrifice, one is lead by the Shekinah (holy spirit) on a path that is specific to the individual. The Torah and the New Testament are both in effect in this belief system.
