Whensoever God's truth is defaced or when any man turns away from the pure simplicity of the Gospel, we must not in any wise spare him, but although the whole world should set itself against us, yet must we maintain the case with invincible constancy, without bending for any creature.
John CalvinWere the judgments of mankind correct, custom would be regulated by the good. But it is often far otherwise in point of fact; for, whatever the many are seen to do, forthwith obtains the force of custom. But human affairs have scarcely ever been so happily constituted as that the better course pleased the greater number. Hence the private vices of the multitude have generally resulted in public error, or rather that common consent in vice which these worthy men would have to be law.
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.
