Old Testament scholars often refer to the religion of the Hebrew Bible as "Yahwism", because Yahweh is the center of this religion, and the
name "Yahweh" is used throughout. During the time between the Testaments, Judaism developed, wherein Yahweh is worshipped, but His
name is not pronounced as a way to avoid saying the
name in vain. Hence the Yahwistic "Yahshua HaMashiach" versus the Jewish "Yeshua HaMashiach".
