From my investigations, the special significance of the Tetragrammaton and the Jewish suppression of pronouncing it, which has left us with some doubts as to what its phonetic sound is truly supposed to be is still with us today with some "Sacred Name" groups making a core doctrinal matter to always say Yahweh and Yeshuah, and scholars contesting that either pronunciations of YHVH are inaccurate or unknown.
In tracing such things I have picked up that stories based on the cabala or cabalistic view point suggest that among some rabbis the name was treated in the same manner that pagans treated the secret names of dragons and demons in which if one knows the secret name of a spirit being that it gives one magical powers over the supernatural being to be able to force that being to do one's bidding. or at least expropriate iits powers. I cannot think of anything so biblically abhorent as believing that there is any way for any human to command God to do anything.
Of course this whole matter can seem to be questionably linked to the meaning and import of the verse in Revelation
Rev 2:17 ......To him that overcometh will I give to eat of the hidden manna, and will give him a white stone, and in the stone a new name written, which no man knoweth saving he that receiveth it.
I see no problem if out of a sense of respect that some choose to try to use the most accurate pronunciation of names from the Bible, in so far as they can reconstruct them, but at the same time I can find no basis to insist that one should insist that such precision is required. Treating anyone's name respectifully seems to be a cross cultural constant. However, what constitutes such respect does vary culture to culture, and what is considered as being friendly in one culture is regarded as being arrogant, disrespectful or an attempt to dominate in another.
There are even some who object to the use of "God" claiming that it a Pagan name and therefore insulting to the Diety. My own research into the matter has indicated that the word "God" in its most ancient forms means essentially "the one who is to be entreated". And if one examines what is said at: http://www.etymonline.com/index.php?allowed_in_frame=0&search=God is:
. And that seems to comport well with what I have searched out previously.Old English god "supreme being, deity; the Christian God; image of a god; godlike person," from Proto-Germanic *guthan (source also of Old Saxon, Old Frisian, Dutch god, Old High German got, German Gott, Old Norse guð, Gothic guþ), from PIE *ghut- "that which is invoked" (source also of Old Church Slavonic zovo "to call," Sanskrit huta- "invoked," an epithet of Indra), from root *gheu(e)- "to call, invoke." .....
If in one's own language and in ones demeanor the English Word "God" or alternatively for a German speaker "Gott" is used in the sense of "the one who is to be entreated" then I see no problem. After all the creation of all the languages is attributed to God, (Genesis 11:1-9).
