Quote by Francis de Sales

“he who caused us to be told that we must prove the spirits, would not have done so unless he knew that we had infallible rules to tell the holy from the false spirit. We have such rules, and nobody denies it. But these deceivers produce rules which they can falsify and adapt to their pretensions, in order that, having rules in their hands, they may gain the credit of being masters in their craft by a visible sign under pretext of which they can form a faith and a religion such as they have imagined.”
