Just ran across a nice quote from Calvin showing what he had to deal with in his day:
Certain Anabaptists of our day conjure up some sort of frenzied excess instead of spiritual regeneration. The children of God, they assert, restored to the state of innocence, now need not take care to bridle the lust of the flesh, but should rather follow the Spirit as their guide, under whose impulsion they can never go astray. It would be incredible that a man’s mind should fall into such madness, if they did not openly and haughtily blab this dogma of theirs. The thing is indeed monstrous! But it is fitting that those who have persuaded their minds to turn God’s truth into falsehood should suffer such punishments for their sacrilegious boldness. Shall all choice between dishonest and honest, righteous and unrighteous, good and evil, virtue and vice, be thus taken away? “Such difference arises,” they say, “from the curse of old Adam, from which we have been freed through Christ.” Therefore, there will now be no difference between fornication and chastity, integrity and cunning, truth and falsehood, fair dealing and extortion. “Take away,” say the Anabaptists, “vain fear — the Spirit will command no evil of you if you but yield yourself, confidently and boldly, to his prompting.” Who would not be astonished at these monstrosities? Yet it is a popular philosophy among those who are blinded by the madness of lusts and have put off common sense.
Tossed about by every wind of doctrine.
