While sin is overflowing, [grace] pours itself forth so exuberantly, that it not only overcomes the flood of sin, but wholly absorbs it.
John CalvinIn a way, the futile excuses many people use to cover their superstitions are demolished. They think it is enough to have some sort of religious fervor, however ridiculous, not realizing that true religion must be according to God's will as the perfect measure; that He can never deny Himself and is no mere spirit form to be changed around according to individual preference.
John CalvinThe Fanaticism which discards the Scripture, under the pretense of resorting to immediate revelations is subversive of every principle of Christianity. For when they boast extravagantly of the Spirit, the tendency is always to bury the Word of God so they may make room for their own falsehoods.
