Test all things, and hold firmly that which is good.
Error, superstition, bigotry, and fanaticism attempt to repress free discussion, by saying that there are certain things which are too sacred in their nature, or which have been too long held, or which are sanctioned by too many great and holy names, to permit their being subjected to the scrutiny of common eyes, or to be handled by common hands. In opposition to all this, Christianity requires us to examine everything - no matter by whom held; by what councils ordained; by what venerableness of antiquity sustained; or by what sacredness it may be invested. We are to receive no opinion until we are convinced that it is true; we are to be subjected to no pains or penalties for not believing what we do not perceive to be true; we are to be prohibited from examining no opinion which our fellow-men regard as true, and which they seek to make others believe. No popular current in favor of any doctrine; no influence which name and rank and learning can give it, is to commend it to us as certainly worthy of our belief. By whomsoever held, we are to examine it freely before we embrace it; but when we are convinced that it is true, it is to be held, no matter what current of popular opinion or prejudice maybe against it; no matter what ridicule may be poured upon it; and no matter though the belief of it may require us to die a martyr’s death.
