“Spare no arrows,” was the motto which Knox wore on his standard; the authority of Scripture, and the force of reasoning, grave reproof, and pointed irony, were in their turn employed by him. In the course of this defense, he did not restrain those sallies of raillery, which the fooleries of the popish superstition irresistibly provoke, even from those who are deeply impressed with its pernicious tendency.
