III. The first mean whereby nature teacheth men to judge good from evil, as well in laws as in other things, is the force of their own discretion. Hereunto therefore St. Paul referreth oftentimes his own speech, to be considered of by them that heard him. “I speak as to them which have understanding, judge ye what I say1.” Again afterward, “Judge in yourselves, is it comely that a woman pray uncovered2?” The exercise of this kind of judgment our Saviour requireth in the Jews3. In them of Berea the Scripture commendeth it4. Finally, whatsoever we do, if our own secret judgment consent not unto it as fit and good to be done, the doing of it to us is sin, although the thing itself be allowable. St. Paul’s rule therefore generally is, “Let every man in his own mind be fully persuaded of that thing which he either alloweth or doth5.”
Some things are so familiar and plain, that truth from falsehood, and good from evil, is most easily discerned in them, even by men of no deep capacity. And of that nature, for the most part, are things absolutely unto all men’s salvation recessary, either to be held or denied, either to be done or avoided. For which cause St. Augustine6 acknowledgeth, that they are not only set down, but also plainly set down in Scripture; so that he which heareth or readeth may without any great difficulty understand. Other things also there are belonging (though in a lower degree of importance) unto the offices of Christian men: which, because they are more obscure, more intricate and hard to be judged of, therefore God hath appointed some to spend their whole time principally in the study of things divine, to the end that in these more doubtful cases their understanding might be a light to direct others. “If the understanding power or faculty of the soul be” (saith the grand physician7) “like unto bodily sight, not of equal sharpness in all, what can be more convenient than that, even as the dark-sighted man is directed by the clear about things visible; so likewise in matters of deeper discourse the wise in heart do shew the simple where his way lieth?” In our doubtful cases of law, what man is there who seeth not how requisite it is that professors of skill in that faculty be our directors? So it is in all other kinds of knowledge. And even in this kind likewise the Lord hath himself appointed, that “the priest’s lips should preserve knowledge, and that other men should seek the truth at his mouth, because he is the messenger of the Lord of hosts8.” Gregory Nazianzen, offended at the people’s too great presumption in controlling the judgment of them to whom in such cases they should have rather submitted their own, seeketh by earnest entreaty to stay them within their bounds: “Presume not ye that are sheep to make yourselves guides of them that should guide you; neither seek ye to overskip the fold which they about you have pitched. It sufficeth for your part, if ye can well frame yourselves to be ordered. Take not upon you to judge your judges, nor to make them subject to your laws who should be a law to you; for God is not a God of sedition and confusion, but of order and of peace9.”
But ye will say that if the guides of the people be blind, the common sort of men must not close up their own eyes and be led by the conduct of such10: if the priest be “partial in the law11,” the flock must not therefore depart from the ways of sincere truth, and in simplicity yield to be followers of him for his place sake and office over them. Which thing, though in itself most true, is in your defence notwithstanding weak; because the matter wherein ye think that ye see, and imagine that your ways are sincere, is of far deeper consideration than any one amongst five hundred of you conceiveth. Let the vulgar sort amongst you know, that there is not the least branch of the cause wherein they are so resolute, but to the trial of it a great deal more appertaineth than their conceit doth reach unto. I write not this in disgrace of the simplest that way given, but I would gladly they knew the nature of that cause wherein they think themselves throughly instructed and are not; by means whereof they daily run themselves, without feeling their own hazard, upon the dint of the Apostle’s sentence against “evil-speakers as touching things wherein they are ignorant12.”
