I am not being rude nor snarky, but you seem to be making a distinction without a difference. It seems to me that you are attempting to add a theological history into the mix. there is already an excellent book on the history of theological beliefs by JND Kelly called Early Christian Doctrines. It is a good read, and used in many seminaries.For the record, you guys are using historical in different contexts. One is historical in the sense it can be traced back through the centuries before the time of their unique doctrines, and the other that they are historical from the time of asserting unique doctrine.
In the sense I meant in the context was a simple recollection of facts, plus I used Britannica as resource with any apparent bias
The second context is based a link you provided. https://www.britannica.com/topic/Anabaptists
I will admit that this link may have some away from my aim, but I was trying to do several things simultaneously. Primary was to demonstrate that the poster was simply pontificating erroneously, providing no historical background to his rant, and to let others in churches which practice believer's baptism see the twisting path which led to the Pilgrims of 1620, and to the many iterations of the Baptist churches.
Because most big questions of history are quite often a question of theology and because the USA (and Germany?) are secular societies, our school systems largely ignore the religious histories which are part and parcel of the history of the original 13 Colonies of the "New World"
There is LOTS more, which I could add, but that would take us further away from the 500th anniversary of the Diet of Worms.
