The philosophy of the Christians is termed simple. But it bestows very great attention to the formation of manners, enigmatically insinuating words of more certain truth respecting God; the principal of which, so far as any earnest serious purpose in those matters is concerned, all will have received when they assume an efficient cause, very noble and very ancient, as the originator of all things that have existence. For Christians leaving to ethical students matters more toilsome and difficult, as, for instance, what is virtue, moral and intellectual; and to those who employ their time in forming hypotheses respecting morals, and the passions and affections, without marking out any element by which each virtue is to be attained, and heaping up, as it were, at random precepts less subtle—the common people, hearing these, even as we learn by experience, make great progress in modesty, and a character of piety is imprinted on their manners, quickening the moral disposition which from such usages is formed, and leading them by degrees to the desire of what is honourable and good.
