Interestingly, there is a whole movement under the umbrella SACRED NAME GROUPS that uses YAHWEH in their worship. Most have nothing to do with the JW's religion, but have similar basic beliefs, e.g. rejection trinity, hellfire, immortal soul, restored earth, etc.
- Witnesses of Yahweh
- Congregation of Yahweh's Witnesses
- Assemblies of Yahweh
- Assembly of Yahweh
- House of Yahweh
- Restored Israel of Yahweh
Not sure exactly what they refer to themselves as, "I'm a Witness of Yahweh" or "We're Yahweh's Witnesses"
Those among the SACRED NAME GROUPS, have differences among themselves as to the proper pronunciation. There was a group called
Assemblies of Yah,
Assemblies of Yahvah, Called out ones of Yah. There is even a group called
Assembly of YHWHHOSHUA, a hybrid of Yahweh and Hoshua. One group uses the name
Yahuwah. Then of course there is Stafford's group that uses the term
Chjristian Witnesses of Jah.
There was an interestly group that WAS an offshoot of the Witnesses in 1942. It was started by C.H. Zook in Brooklyn, later in Leviitown, NU. They even had a branch in Vienna, Austria. They called themselves the
Servants of Yah. He taught that Jehovah was the name of Satan and that God's true name is Yah. They believed in the 144,000 in heaven and the rest of mankind on paradise earth, other than that they deny Armageddon, the flood, water baptism, the ransom sacrifice, the existence of Satan as a real individual. They were universalist. Not sure how long they lasted. Probably as long as Zook led them. Usually, groups like these die off once the leader dies.
