Humour aside, this is actually why I shy away from Calvinism and other ‘magisterial’ streams of Protestantism like Lutheranism, much as I respect them in other ways.
Lacking a nonviolent ethic, there is nothing within their theologies that precludes the burning of heretics, as history has demonstrated. That the burning is more verbal than physical these days is a vast improvement, but its still a problem as far as I am concerned.
I wonder though, has anyone ever attempted to formulate a nonviolent Calvinist ethic? I wonder if it is possible.
