I am verily persuaded, that Almighty God, before ever he spoke by an external Voice to Adam, to make him sensible of his Duty, spoke to him inwardly in his Conscience, by giving him the vast and immense Idea of a Being sovereignly perfect, and printing on his Mind the eternal Laws of Just and Honest; so that Adam thought himself oblig’d to obey his Maker, not so much because of a certain Prohibition outwardly striking upon his Organs of Sense, as because that inward Light which enlighten’d his Conscience e’er God had utter’d himself, continually presented the Idea of his Duty, and of his Dependance on the Sovereign Being: Consequently it may be truly affirm’d, with regard even to Adam, that the reveal’d Truth was subordinate to the natural Light in him, and from thence was to receive its Sanction and Seal, its statutable Virtue, and Right to oblige as Law. And by the way, ’tis very probable, that had not the confus’d Sensations of Pleasure, excited in the Soul of our first Parent upon proposing the forbidden Fruit, drown’d the eternal Ideas of natural Equity (which must ever happen by reason of that essential Limitedness in created Spirits, rendring ’em incapable of immaterial Speculations, and of the lively and hurrying Sen-<51>sations of Pleasure at one and the same time). It is, I say, very probable he had never transgrest the Law of God; which ought to be a continual Warning to us, never to turn away our Eyes from that natural Light, let who will make Propositions to us of doing this thing or that with regard to Morality.
Shou’d a Casuist therefore come and inform us, he finds from the Scriptures, that ’tis a good and a holy Practice to curse our Enemys, and those who persecute the faithful; let’s forthwith turn our Eyes on natural Religion, strengthen’d and perfected by the Gospel, and we shall see by the bright shining of this interior Truth, which speaks to our Spirits without the Sound of Words, but which speaks most intelligibly to those who give Attention; we shall see, I say, that the pretended Scripture of this Casuist is only a bilious Vapor from his own Temperament and Constitution. In a word, ’twill afford us an Answer to the Example which the Psalmist furnishes him, to wit, that a particular Case where God interposes by a special Providence, is by no means the Light by which we must walk, and derogates not from the positive Command propos’d universally to all Mankind in the Gospel, of being meek and lowly in heart, and praying for those who persecute us; much less from that natural and eternal Law which discovers to all Men the Ideas of Honest, and which discover’d to so many Heathens, that ’twas a glorious part, and highly becoming the Dignity of human Nature, to forgive those who have offended us, and to return ’em Good for Evil. <52>
But that which is highly probable with regard to Adam in a state of Innocence, to wit, his discovering the Justice of God’s verbal Prohibition, by comparing it with his previous Idea of the Supreme Being, was become indispensably necessary after his Fall: for having experienc’d, that there were two kinds of Agents, which concern’d themselves in directing him what to do, ’twas absolutely necessary he shou’d have a Rule to judg by, for fear of confounding what God shou’d outwardly reveal to him, with the Suggestions or Inticements of the Devil disguis’d under the fairest Appearances. And this Rule cou’d be nothing else than natural Light, than the Conscience of Right and Wrong imprinted on the Souls of all Men; in a word, than that universal Reason which enlightens Spirits, and which is never wanting to those who attentively consult it, especially in those lucid Intervals when bodily Objects possess not the whole Capacity of the Soul, either by Images of their own, or by the Passions they excite in the Heart.
All the Dreams of old, all the Visions of the Patriarchs, all Discourses which strike the Sense as utter’d by God, all Appearances of Angels, all Miracles, every thing in general must have pass’d the Test of natural Light; otherwise how cou’d it appear, whether they proceeded from that evil Principle which had formerly seduc’d Adam, or from the great Creator of Heaven and Earth? ’Twas necessary, that God shou’d mark whatever came from him with some certain Character, bearing a Conformity with that interior Light which communicates it self immediately to all Spirits, or which at least shou’d not ap-<53>pear repugnant to it; and this once ascertain’d, all the particular Laws of a Moses suppose, or any other Prophet, were entertain’d with Pleasure, and as coming from God, altho they might have ordain’d things indifferent in their own nature.
Moses himself, we know, enjoin’d the Israelites on the part of God, not to believe every Worker of Miracles, nor every Prophet; but examine his Doctrines, and receive or reject ’em according as they were consonant or contrary to the Law which was given by God. There was this difference then between the Jews after the days of Moses and the antient Patriarchs, that these were oblig’d to compare the Revelations made to them with natural Light alone, those with the Light of Nature, and with the positive Law. For this positive Law, once vouch’d by the natural Light, acquir’d the Quality of a Rule and Criterion, in the same manner, as a Proposition in Geometry once demonstrated from incontestable Principles, becomes it self a Principle with regard to other Propositions. Now as there are certain Propositions, which one wou’d be easily inclin’d to admit, were they not attended with harsh and pernicious Consequences, but which are rejected with horror as soon as these Consequences appear; so that instead of saying, These Consequences are true because they arise from a true Principle; This Principle, say we, is false, because such false Consequences follow from it: So there are those, who without reluctance wou’d believe, that some things might have bin reveal’d by God, did they not consider the Consequences of ’em; but when they see what these things lead to, they conclude, they are not from God: and this Argument a posteriori <54> for them has the value of the strictest Demonstration.
Thus about the beginning of the Saracen Empire several Jews renounc’d their Religion, and dedicated themselves to the Pagan Philosophy,37 pretending they had discover’d in the ceremonial Law of Moses a world of unprofitable or absurd Precepts, which they perceiv’d not to be founded on any solid Reasons of their Institution or Prohibition, and thence concluding, that such a Law cou’d not be given by God. Their Consequence without doubt was fairly drawn, but they suppos’d amiss: They had not consider’d the incontestable Proofs which God himself had given of Moses’s Divine Mission, Proofs which will bear the strictest Trial at the Bar of the pure and living Ideas of natural Metaphysicks, in virtue of which each particular Law of Moses implicitly carrys a good Reason with it. Besides, they had not Strength enough or Compass of Judgment, to comprehend the drift of the ceremonial Laws, which, with regard to the Character of the Jewish Nation, and their Proneness to Idolatry, or as they were Figures and Types of the Gospel, were all founded on solid Reasons. Thus they were in an Error as to the point of Fact; and tho the Consequence follow’d justly and necessarily from their false Principle, they were wrong nevertheless. But by this example we see of what importance it is, that natural Light shou’d find nothing absurd in any thing propos’d as Revelation; for that which might otherwise appear most certainly reveal’d, will cease to appear so, when once found repugnant to that primitive, universal, and mother <55> Rule of judging, and of discerning Truth from Falshood, Good from Evil.
Every Philosophical attentive Mind clearly conceives, that this lively and distinct Light which waits on us at all Seasons, and in all Places, and which shews us, That the whole is greater than its part, that ’tis honest to be grateful to Benefactors, not to do to others what we wou’d not have done to our selves, to keep our Word, and to act by Conscience; he conceives, I say, very clearly, that this Light comes forth from God, and that this is natural Revelation: How then can he imagine, that God shou’d afterwards contradict himself, and blow hot and cold, by speaking to us outwardly himself, or sending his Messengers to teach us things directly repugnant to the common Notions of Reason? An Epicurean Philosopher reasons very justly, tho he applies his Principles badly, when he says, that since our Senses
