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".
