"The Puritan core of the parliamentary party could not abandon their belief in the supremacy of truth and that belief had become incompatible with the Foxeian tradition of obedience to the godly prince. Thus anti-Catholicism was turned against the court and even the monarch and the force of it carried men into rebellion. It was the king therefore who had opened the way for the call to apocalyptic warfare that thundered from the London pulpits in 1642 and who had forced a section of the gentry into an unnatural alliance with radical Puritans from further down the social scale."
