If they dropped the name Jehovah altogether I think it could actually be enough to cause some sort of split. Their hierarchical structure strongly inhibits the sectarian tendency to splinter but dropping God’s name might just be enough to do it.
But what could they come up with that still includes the name Jehovah?
Christian Witnesses of Jehovah? - Uses the word “Christian” which the NWT says was adopted by divine providence in Acts
Jehovah’s Christian Witnesses? - They’ve used that a couple of times in the past
Witnesses of Jah and Jesus? - Greg Stafford might have got there first
The Way of Jehovah? - Sounds even more culty
I don’t know. 🤔
