Jeffro said "Can you imagine if JWs did abandon 1914 though. Poor old dupes like ‘scholar’ would have to start saying 1914 and 607 BCE never actually made any sense."
1914 is not a JW originated doctrine.
It started with a prophecy given by Nathan to David for his offspring to be king on Jehovah's throne forever leading to Jesus.
That was put on pause when the kings in the line of David were made vassal to Babylon in 607 and at the destruction of Jerusalem in 587. Daniel was given a time table of 2520 years for that pausing and that ran from 607 to 1914 when Jesus was installed as king in Heavenly Jerusalem.
It is known and written and can not be done away with. Jesus is king and nothing can change that.
