"Natural religion, in its full extent, was nowhere that I know taken care of by the force of natural reason. It should seem, by the little that has hitherto been done in it, that it is too hard a task for unassisted reason to establish morality in all its parts, upon its true foundation, with a clear and convincing light. And it is at least a surer and shorter way to the apprehensions of the vulgar and mass of mankind, that one manifestly sent from God, and coming with visible authority from him, should, as a king and law-maker, tell them their duties and require their obedience, than leave it to the long and sometimes intricate deductions of reason to be made out to them. Such trains of reasoning the greater part of mankind have neither leisure to weigh, nor, for want of education and use, skill to judge of.... You may as soon hope to have all the day-labourers and tradesmen, the spinsters and dairy-maids, perfect mathematicians, as to have them perfect in ethics this way. Hearing plain commands is the sure and only course to bring them to obedience and practice. The greater part cannot learn, and therefore they must believe." It is true that reason quickly apprehends and approves of these truths, when once delivered, but "native and original truth is not so easily wrought out of the mine as we, who have it delivered already dug and fashioned into our hands, are apt to imagine;" moreover, "experience shows that the knowledge of morality by mere natural light (how agreeable soever it be to it) makes but a slow progress, and little advance in the world." The evidence of Christ's mission is to be found in the miracles, the occurrence and the divine origin of which Locke, both here and in the paper on Miracles published among his Posthumous Works, appears to have thought it impossible to gainsay. "The miracles he did were so ordered by the divine providence and wisdom, that they never were nor could be denied by any of the enemies or opposers of Christianity." And "this plain matter of fact being granted, the truth of our Saviour's doctrine and mission unavoidably follows." But once acknowledge the truth of Christ's mission, and the rule of life is evident. "To one who is once persuaded that Jesus Christ was sent by God to be a King, and a Saviour of those who do believe in him, all his commands become principles; there needs no other proof for the truth of what he says, but that he said it. And then there needs no more, but to read the inspired books, to be instructed; all the duties of morality lie there clear, and plain, and easy to be understood."
