Religionists always wind up hoisted on their own pattard in so many ways.
Not just in prediction setting. I like an example from Adventism. The adventists believe in the "messages of the three angels". The second angel cried out for adventists to "leave Babylon" and form a seperate church, and this cry went forth in a particular speech delivered by an Adventist minister in 1842. Anyone who reads that speech (in original form) will immediately see that the speaker called adventists to" leave babylon" for a specific reason, that reason being that Babylon "spiritualized" the return of Christ, that they believed in an INVISIBLE return. Adventists at that time believed in a LITERAL return. Yet 4 years later they "spiritualized" the return themselves and declared Christ returned Invisibly in 1844. So they contradicted their own reason for forming their church in the first place.
This is why old material is so revealing and cults dont like you inspecting their history. Anyone who reads Russell will see that he condemned Adventists for practises that, years later, he adopted himself. Religionist cult leaders always fall into these same traps
