In the following quote, Chalmers explains how a territorial establishment, where parish missions bring the Gospel to every home and hearth, is a double blessing. Even if few souls are saved, the social and moral impact of the Gospel effort leavens the lump:
“And perhaps it will give in your eyes less of a Utopian, and more of an experimental character, to our anticipations of a result so general—if we ask you to consider the just observation of Mr. Wilberforce, on the effect of Christianity even beyond the circle of its own proper and genuine disciples. It elevates the general standard of morals, in every country or neighbourhood which it enters. Even though it should but spiritualize the few, it civilizes the many. Over and above its direct influence on those whom it converts, it has, through the medium of their example and their virtues, a reflex or secondary influence on the families of every little vicinity around them-insomuch that the sanctities and the extraordinary graces of a small number, with the influence of a purifying and preserving salt on the general mass, tell, by a certain overawing power, in restraining the profligacies, and so in raising the character for decency and morals of society at large. This will be remarkably seen in any parish that is under a reclaiming process from the out-fields of heathenism, if the experiment be but well and vigorously conducted. We do not say that the minister will Christianize all; or that he will introduce the worship of God, the voice of psalms, into every family. But the melody that is heard in the habitations of the righteous, will have a certain softening and subduing effect on the inmates of other habitations; and it will be found no romance, but in strict accordance with the realities of human nature, if-by means of his schools and of his other parochial institutes, and (of no small account either) if, by means of his own frequent and various intercourse with the people, and the dignifying effect upon all the householders of their personal acquaintance with the clergyman, and of the personal cognizance which he takes of them and of their families—he mollifies, and to a very great degree, the general aspect of that parochial community over which he presides ; and bequeaths to his successors a far blander and better generation, than he had to encounter himself at the outset of his great undertaking” (Works 14:334-335)
