Such being the case, the demands you can make on a man for manliness must depend for their answer on the amount of piety on deposit in his character; so it becomes important to know the condition of this town in respect of piety, for if this be not right in the above sense, nothing else is right; or, to speak more clerically, "Unless the Lord keep the city, the watchman waketh but in vain," and unless piety be developed or a-developing in men, it is vain for the minister to sit up late of a Saturday night to concoct his sermon, and to rise up early of a Sunday morning to preach the same; he fights but as one that beateth the air, and spends his strength for that which is nought. They are in the right, therefore, who first of all things demand piety: so let us see what signs or proof we have, and of what amount of piety in Boston. To determine this, we must have some test by which to judge of the quality, distinguishing piety from impiety, and some standard whereby to measure the quantity thereof; for though you may know what piety is in you, I what is in me, and God what is in both and in all the rest of us, it is plain that we can only judge of the existence of piety in other men, and measure its quantity by an outward manifestation thereof, in some form which shall serve at once as a trial test and a standard measure. Now, then, as I mentioned in that former sermon, it is on various sides alleged that there are two outward manifestations of piety, a good deal unlike: each is claimed by some men as the exclusive trial test and standard measure. Let me say a word of each. I. Some contend for what I call the conventional standard; that is, the manifestation of piety by means of certain prescribed forms. Of these forms there are three modes or degrees: namely, first, the form of bodily attendance on public worship; second, the belief in certain doctrines, not barely because they are proven true, or known without proof, but because they are taught with authority; and third, a passive acquiescence in certain forms and ceremonies, or an active performance thereof. II. The other I call the natural standard; that is, the manifestation of piety in the natural form of morality in its various degrees and modes of action. * * * * * It is plain, that the amount of piety in a man or a town, will appear very different when tested by one or the other of these standards. It may be that very little water runs through the wooden trough which feeds the saw-mill at Niagara, and yet a good deal, blue and bounding, may leap over the rock, adown its natural channel. In a matter of this importance, when taking account of a stock so precious as piety, it is but fair to try it by both standards. * * * * *
