Watchtower is an organization but its a religion...it claims Jesus became invisibly present in 1914.
There are some Jews (I believe it is those who accept the Patriarchs) who, rejecting Jesus Christ as the Messiah, say that the Messiah is not a person but an Age. So a New Age starts when a particular moment in time comes.
Is it a secular idea? Is it a religious idea? Is is a secular, religous idea? Whatever, it is similar to Communism and the idea of a search for a society through a 3-stage theory of progress bit like a.......pyramid.
Impressed by progress, Joseph Rutherford felt that cream separators were evidence the Messiah had arrived. He also boldly told everyone that millions now living would never die and that all religion was a snare and a racket.
