6. There is but one being, who is, as God is often said to be, the best and the greatest; therefore, if there were more Gods than one, either one must be supposed to be more excellent than another, or both equally excellent. If we suppose the former of these, then he, who is not the most excellent, is not God; and if the latter, that their excellencies are equal, then infinite perfection would be divided, which is contrary to the idea thereof, as was before hinted; as well as to what is expressly said by God, To whom will ye liken me, or shall I be equal? saith the Holy One, Isa. xl. 25. From these, and several other arguments to the same purpose, which might have been taken from every one of the divine attributes, and from all essential and relative glory which belongs to him, the unity of the divine essence appears, even to a demonstration. And indeed to assert that there are more Gods than one is, in effect, to say that there is no God; so the apostle deems it, when he tells the church at Ephesus, that, before their conversion, when they worshipped other gods, they were without God in the world, which implies as much as that they were atheists therein, as the words αθεοι ἐν τω κόσμω may, with equal propriety, be rendered.[[66]]
Having considered the unity of the Godhead, not only as evinced from scripture, but as it may be demonstrated by the light of nature, it will be necessary that we obviate an objection that may be brought against this latter method of proving it, viz.
Object. If the unity of the Godhead might be known by the dictates of nature, or demonstrated by other arguments, besides those which are matter of pure revelation, how comes it to pass that the heathen owned, and worshipped, a plurality of gods? and as it was not one particular sect among them that did so, but this abominable practice universally obtained, where revealed religion was not known, therefore, though this be an undoubted truth, yet it is not founded in the light of nature.
Answ. That they did so is beyond dispute, especially after idolatry had continued a few ages in the world, and so had extinguished those principles of revealed religion, which mankind, before this, were favoured with; yet it must be considered, that though the ignorant and unthinking multitude, among them, believed every thing to be a God, which the custom of the countries where they lived had induced them to pay divine adoration to, yet the wiser sort of them, however guilty of idolatry, by paying a lower kind of worship to them, have, notwithstanding, maintained the unity of the Godhead, or that there is one God superior to them all, whom they often call the father of gods and men; to whom probably the Athenians erected that altar, as the apostle Paul observes, with this inscription, To the unknown GOD; because he says, in the words immediately following, Whom therefore ye ignorantly worship, him declare I unto you, Acts xvii. 23.
This appears from what they assert to the same purpose, whereby they plainly discover their belief of but one supreme God, who has all the incommunicable perfections of the divine nature, however, in other instances, their conduct seemed to run counter to their method of reasoning: thus it appears, by their writings, that many of them assert that there is a God, who is the first cause, or beginning, of all things; and that he was from eternity, or in the beginning, and that time took its rise from him; that he is the living God, the fountain of life, and the best of all beings[[67]]: Also, that this God is self-sufficient, and therefore it is absurd to suppose that he stands in need of, or can receive advantage from, any one[[68]]; and that he is the chief good, or contains in himself whatever is good, and that by him all things consist; and that no one hath enough in himself to secure his own safety and happiness, which is to be derived from him[[69]].
And there are others also, who plainly assert the unity of God in as strong terms, as though they had learned it from divine revelation, calling him, the beginning, the end, and author of all things; who was before, and is above all things, the Lord of all, the fountain of life, light, and all good, yea, goodness itself; the most excellent being; and many other expressions to the like purpose. I could multiply quotations for the proof of this, from Proclus, Porphyry, Iamblicus, Plotinus, Plutarch, Epictetus, and several others; but this has been already done by other hands[[70]]; by which it appears, that though they mention other gods, they suppose them to be little more than titular or honorary gods; or at least persons, who were the peculiar favourites of God, and admitted to the participation of divine honours, as well as employed in some part of the government of the world. They frequently speak of them as having derived their being from God, whom they call the cause of causes, the God of gods. Some of them speak of God in the singular number, throughout the greatest part of their writings, and only make mention of the gods occasionally, especially when they treat of those works that become a God, or the greatest honours that are due to him; thus Seneca and Plato, and, in particular, the latter of them says, concerning himself[[71]], that when he wrote any thing in a grave and serious manner, his custom was, to preface his epistles with the mention of one God; though, it is true, when he wrote otherwise, he used the common mode of speaking, and talked of other gods; and it is observed, in his writings, that he sometimes uses this phrase; If it please God, or by the help of God, not the gods.
But, notwithstanding this, they were all idolaters, for they joined in the rites of worship performed to the false gods of their respective countries; yea, Socrates himself, who fell under the displeasure of the Athenians, for asserting the unity of the Godhead, which cost him his life, did not refuse to pay some religious honour to the heathen gods. So that it is plain they paid some religious worship to them, but it was of an inferior and subordinate nature, not much unlike to that which the Papists give to saints and angels: but they are far from setting them upon a level with God; for they confess they were but men, who formerly lived in this world; they give an account of their birth and parentage; where they lived and died; write the history of their lives, and what procured them the honour they suppose them after death advanced to[[72]]; how some of them obtained it, as the reward of virtue, or in commemoration of the good they had done to the world in their life: as some were advanced to this honour, who were the inventors of arts, beneficial to mankind, or were successful in wars, or a public blessing to the country where they lived, others had this honour conferred upon them, especially among the Romans, at the request of their surviving friends; and this was done after Julius Cæsar’s time, by the decree of the senate, who, at the same time, when they ranked them among the number of their gods, appointed also the rites of worship that should be paid to them; and some of the Roman emperors obliged the senate to deify them while they were alive. These things are very largely insisted on, by many ancient and modern writers[[73]]; so that, upon the whole, it plainly appears, that, whatever they say of a plurality of gods, the wiser sort among the heathen did not deny the unity of the divine essence, in the highest and most proper sense; and, inasmuch as they received the knowledge hereof from the light of nature, we may from hence conclude that this truth might be known that way, as well as by divine revelation.
We shall conclude with some practical inferences from the doctrine contained in this answer.
1. Since he, who is the object of our worship, is the living God; this reproves that lifeless formal way, in which many address themselves to him, in the performance of religious duties, without that reverence and due regard to the divine perfections, which are contained in this character of the Godhead. It is also a very great aggravation, not only of apostacy, but of any degree of backsliding, in those who have made a profession of religion; that it is a departure from the living God, Heb. iii. 12. Is he the God and giver of life, and shall we forsake him, who has the words of eternal life, John vi. 68. whose sovereign will has the sole disposal thereof?
Again, this consideration, of his being the living God, renders his judgments most terrible, and his wrath insupportable; as the apostle says, It is a fearful thing to fall into the hands of the living God, Heb. x. 31.
