The WTS now teaches that the last days began with Jesus installation as king in heaven, now 1914 (once was 1878).
When was Jesus anointed as king in the first century? 29 CE at his baptism or 33 CE when he was resurrected and returned to heaven and sat at God’s right hand until he exercised his kingship over all the earth in the midst of his enemies?
The WTS teaches that the last days now will end at the culmination of the great tribulation at Armageddon.
The great tribulation of the first century Jews began and ended with the Romans coming up against them and finally destroyed the temple and all records of their lineage, not being able to determine who was of the tribe of Levi or the family of Aaron, the high priest family.
