The author has made no attempt to draw parallels with modern evangelical Protestantism.
Where did English Protestants come from? They were educated at Cambridge. How did they gain power? Henry VIII had relied both on English Catholics and Protestants in his machinations against the power of the Papacy. After he was done, the Catholics found many of their own tracts being used against English Catholicism. How was it cemented? Henry's son, and only heir apparent, was educated entirely by Protestants.
It should also be noted that many of Henry's wars, in Scotland and the raids in France, were against Catholic powers.
