No years ago I did alot of study on this. YHVH is from the jewish. When a catholic monk translated the name into english he used the J instead of Y because it has the same numerical value and sound. YHVH is written vertically in hebrew to form a picture of a man. YHVH stands for the four elements and unwritten vowels in hebrew the 5th element spread out which is noted as ether. Y=Fire H=Water V=Air H=Earth. Each letter also stand for 4 basic anatomical body aspects. GOD is all as one. So it not only reveals gods name but reveals his actual being.Donann...I believe when he says there is no YHVH I believe he is referring to Hebrew...
You are looking at a Christian view of Judaism...while talking to Jews...
