TCD:
Many people use G*D for multiple reasons. Some believe that it is wrong to spell out the name of G*D. It limits that which is unlimitable. Others do so in respect to those who believe it is wrong to write out the word for theological reasons. So as not to denigrate the word. And there are those who don't do so because they truly believe that it is wrong to do so, again for theological reasons. Those people sincerely believe that if one writes out the name of G*D, that name itself is holy and if it falls on the floor or is thrown in the garbage, then it denegrates the Holy One.
I don't mean to answer for Paul. Sorry if I step on your toes, Paul.
I personally write out G*D's name this way in respect to those who honestly believe that way, and also, because, philosophically, I think it's impossible to limit the Unlimitable.
Shalom!
