Gumby: Yhwh in Ugarit, really? I'd like to know the references... Of course El is known in Ugarit as the Father of gods or supreme god, which is reflected in many Bible texts as well. One of the most interesting is the plainly polytheistic Deuteronomy 32:8f, which (when reconstructed by crossing the Hebrew Masoretic text and the Greek Septuagint which are two different attempts at hiding the first meaning) reads: "When Elyon (title of El) apportioned the nations, when he divided humankind, he fixed the boundaries of the peoples according to the number of the sons of El (= gods); Yhwh's own portion was his people, Jacob his allotted share." That is: Yhwh is only one of El's sons, and he receives Israel as his portion whereas his god-brothers are given other peoples.
However, this does not explain the name "Yhwh". In the Biblical texts as well as in inscriptions such as Mesha's stele it appears rather as a southern godname (whereas Ugarit = Ras Shamra is on the Phoenician coast, north of Palestine). There is an old theory by Driver, still held by some, that interprets it as a title, from the Biblical expression Yhwh Sabaoth: it would be "He [El] who creates the [heavenly] armies" (and imply the pronunciation yahweh); but I don't find it very convincing, especially because of the distinction between El and Yhwh. When you compare Bible texts with Ugarit's Yhwh seems to be more in the position of Hadad = Baal, the most prominent son of El. But I'll try to give a fresh look at this someday.
Belbab: syllabic writing (including the vowels) is much older than consonantic alphabetical writing (such as Ugarit's, and Hebrew): in Sumerian and Egyptian for instance. And, to me, the explanation of Yhwh in Exodus 3 seems to be a late attempt to explain away the personal name of a god which has become God in the meantime, and for this reason does not need a name anymore. Anyway, I liked your quotation very much...
Minimus: I just use "Jehovah" when discussing this subject (by the way, I'm not a theist anymore).
