I think that was more of a Christian thing? I could be wrong though

I mean I know saying Lucifer or demon was a Christian thing, idk for sure about not saying God. What I can say is that I was raised to say Adonai or Hashem, which are both traditional euphemisms to refer to him without saying his name, like saying The Lord. God was acceptable, but lightly discouraged in favor of the other two because the others were more culturally specific- just saying God was seen as more of a Christian thing. But that doesn't really tell us about the history.
