who is the supreme being in Judaism?
There is only one God in Judaism because it is a monotheistic (one god) religion, and the Jews call Him with names such as Adonai or Hashem that represent His true name of YHVH. Most Jews use the name “HaShem” that translates to “The Name,” because they cannot say His true name, YHVH, out of respect for His holiness. In reading God’s name from the Hebrew holy book, the Torah, the name is Adonai or “My Lord.” There are numerous other names for God in Judaism that all honor Him without saying his holy name aloud.
Judaism was one of (if not the first) monotheistic religions. There is only one God, and He is called by various names, such as Adonai or Hashem.
The Creator has one true name which is represented by the letters Y, H, V and H in English. The Hebrew letters are “yud, hei, vav, hei”. These four letters are referred to as the tetragrammaton and are a contraction of the Hebrew words for, “was, is, and will be”. His true name was only said in the Temple and with the Temple’s destruction we lost the correct pronunciation.
In the Tanach (Jewish Bible), there are 72 different ‘names’ used for The Creator, these aren’t actual names though, they’re descriptions of Him that are contextual. In daily conversation, most Jews use the name ‘HaShem’ which literally translates to ‘The Name’ in reference to His true name.
