The English Baptists did break off from the Anglicans, who broke from Rome. But they aren't the only Baptists. Furthermore, most individuals today who are Baptists, were never part of the Romish church. AND most Baptist churches today, in 2011, came into being totally apart from any influence or involvement from Rome.
Do you consider Baptists to be Protestants? I ask this because different Baptists are either for this statement or against it and I don't wish to offend you by saying you are or are not Protestant
