Back in 1931 the head executive leader of the WTS. J. Rutherford made a new name for the organization which he personally was the top orchestrated leader and called it the Jehovah's Witnesses.
He also proclaimed that the organization was replicated the first century disciples of Jesus Christ in preaching the New Kingdom to come. Made the doctrine that Jesus had taken his heavenly position in 1914 and that the end times started since that year and that Armageddon therefore was to come within a generation of 1914.
Well in reality the 1914 doctrine was a false teaching since Jesus himself said that no one knows of the time and admonished his followers to not set a time upon god's own sacred time.
In doing what Rutherford did and the man who preceded him C T Russell was actually an act of scriptural apostasy accord to the bible and the words of Jesus Christ..
These men held onto these doctrines for their own lifetime and the majority of those doctrines are to held by practicing JWS today.
These were the core doctrines which the organization built up itself since its inception but they were obviously not inline with truthful bible interpretation, they were inline with those men's self made doctrines which were no doubt influenced by their own literature proliferation agenda.
One could say then that the people who were ever involved with the WTS/JWS and publicly distributed the WTS's literature were themselves enacting in sinful behavior or apostasy.
