Who Wrote This

“If you do not contend with your whole heart against the impious government of the pope, you cannot be saved. Whoever takes delight in the religion and worship of popery, will be eternally lost in the world to come. If you reject it, you must expect to incur every kind of danger, and even to lose your lives. But it is far better to be exposed to such perils in this world than to keep silence. So long as I live I will denounce to my brethren the sore and the plague of Babylon, for fear that many who are with us may fall back like the rest into the bottomless pit of perdition.”
