The word YHWH is not a name, it is more like a title or description and means something like I am that I am...It was only used by the priests and scribes. Ordinary people to this day use Elohim in Hebrew. Most of the common folk of Jesus' time spoke Aramaic and would have used Alahu or Allah. Christian Arabs as well as Muslims use Allah as the name for God. I have met Arabs of both persuasions and know this to be the case.
Our loyalties are to the species and the planet. We speak for Earth. Our obligation to survive is owed not just to ourselves but also to that Cosmos, ancient and vast, from which we spring.
--Carl Sagan, 1934-1996
