Throughout human history and in virtually all cultures, there is a status reserved for God. But not every society call him by the three-letter name: Judaism variously terms the being. In the Hebrew Bible (simply known to most Christians as the “Old Testament”), four-letter term יהוה (YHWH). This YHWH or יהוה is also known as the Tetragrammaton.
In Islam the being is Allah (الله ), which literally translates “the God”, with the initial “Al-“ being the definite article. It is noteworthy that Muslims or followers of Muhammad are not the only ones who use الل or Allah to denote the supreme being; Mizrahi Jews, Arab Christians, Bahá’ís, Arabic-speakers, Indonesian and Maltese Christians also use the term.
Again, on its etymology, most Christians do not go beyond or out of their printed holy texts, the Bible, to find any known evolution. Because the idea of the being is considered “unchanging”, revolutionary connotations about it are often rejected as undermining the being’s all-too-powerfulness. This way, religious hierarchs are able to secure their power and strongholds over their followers and communities.
In justifying the exalted and domineering position of the Christian religion, Muller further states that “God was most likely an old heathen name of the Deity, and for such a name the supposed etymological meaning of good would be far too modern, too abstract, too Christian.”
