Of the many controversies which were rife during the first half of the eighteenth century, none raised a question of greater importance than that which lay at the root of the Deistical controversy. That question was, in a word, this--How has God revealed Himself--how is He still revealing Himself to man? Is the so-called written Word the only means--is it the chief means--is it even a means at all, by which the Creator makes His will known to His creatures? Admitting the existence of a God--and with a few insignificant exceptions this admission would have been made by all--What are the evidences of His existence and of His dealings with us?
During the whole period of pre-reformation Christianity in England, and during the century which succeeded the rupture between the Church of England and that of Rome, all answers to this question, widely though they might have differed in subordinate points, would at least have agreed in this--that _some_ external authority, whether it were the Scripture as interpreted by the Church, or the Scripture and Church traditions combined, or the Scripture interpreted by the light which itself affords or by the inner light which lighteth every man that cometh into the world, was necessary to manifest God to man. The Deists first ventured to hint that such authority was unnecessary; some even went so far as to hint that it was impossible. This at least was the tendency of their speculations; though it was not the avowed object of them. There was hardly a writer among the Deists who did not affirm that he had no wish to depreciate revealed truth. They all protested vigorously against the assumption that Deism was in any way opposed to Christianity rightly understood. 'Deism,' they said, 'is opposed to Atheism on the one side and to superstition on the other; but to Christianity--true, original Christianity--as it came forth from the hands of its founder, the Deists are so far from being opposed, that they are its truest defenders.' Whether their position was logically tenable is quite another question, but that they assumed it in all sincerity there is no reason to doubt.
It is, however, extremely difficult to assert or deny anything respecting the Deists as a body, for as a matter of fact they had no corporate existence. The writers who are generally grouped under the name wrote apparently upon no preconcerted plan. They formed no sect, properly so-called, and were bound by no creed. In this sense at least they were genuine 'freethinkers,' in that they freely expressed their thoughts without the slightest regard to what had been said or might be said by their friends or foes. It was the fashion among their contemporaries to speak of the Deists as if they were as distinct a sect as the Quakers, the Socinians, the Presbyterians, or any other religious denomination. But we look in vain for any common doctrine--any common form of worship which belonged to the Deists as Deists. As a rule, they showed no desire to separate themselves from communion with the National Church, although they were quite out of harmony both with the articles of its belief and the spirit of its prayers. A few negative tenets were perhaps more or less common to all. That no traditional revelation can have the same force of conviction as the direct revelation which God has given to all mankind--in other words, that what is called revealed religion must be inferior and subordinate to natural--that the Scriptures must be criticised like any other book, and no part of them be accepted as a revelation from God which does not harmonise with the eternal and immutable reason of things; that, in point of fact, the Old Testament is a tissue of fables and folly, and the New Testament has much alloy mingled with the gold which it contains; that Jesus Christ is not co-equal with the one God, and that his death can in no sense be regarded as an atonement for sin, are tenets which may be found in most of the Deistical writings; but beyond these negative points there is little or nothing in common between the heterogeneous body of writers who passed under the vague name of Deists. To complicate matters still further, the name 'Deist' was loosely applied as a name of reproach to men who, in the widest sense of the term, do not come within its meaning. Thus Cudworth, Tillotson, Locke, and Samuel Clarke were stigmatised as Deists by their enemies. On the other hand, men were grouped under the category whose faith did not rise to the level of Deism. Thus Hume is classified among the Deists. Yet if the term 'Deism' is allowed to have any definite meaning at all, it implies the certainty and obligation of natural religion. It is of its very essence that God has revealed himself so plainly to mankind that there is no necessity, as there is no sufficient evidence, for a better revelation. But Hume's scepticism embraced natural as well as revealed religion. Hobbes, again, occupies a prominent place among the Deists of the seventeenth century, although the whole nature of his argument in 'The Leviathan' is alien to the central thought of Deism. Add to all this, that the Deists proper were constantly accused of holding views which they never held, and that conclusions were drawn from their premisses which those premisses did not warrant, and the difficulty of treating the subject as a whole will be readily perceived. And yet treated it must be; the most superficial sketch of English Church History during the eighteenth century would be almost imperfect if it did not give a prominent place to this topic, for it was the all-absorbing topic of a considerable portion of the period.
The Deistical writers attracted attention out of all proportion to their literary merit. The pulpit rang with denunciations of their doctrines. The press teemed with answers to their arguments. It may seem strange that a mere handful of not very voluminous writers, not one of whom can be said to have attained to the eminence of an English classic,[147] should have created such a vast amount of excitement. But the excitement was really caused by the subject itself, not by the method in which it was handled. The Deists only gave expression--often a very coarse and inadequate expression--to thoughts which the circumstances of the times could scarcely fail to suggest.
The Scriptures had for many years been used to sanction the most diametrically opposite views. They had been the watchword of each party in turn whose extravagances had been the cause of all the disasters and errors of several generations. Romanists had quoted them when they condemned Protestants to the stake, Protestants when they condemned Jesuits to the block. The Roundhead had founded his wild reign of fanaticism on their authority. The Cavalier had texts ready at hand to sanction the most unconstitutional measures. 'The right divine of kings to govern wrong' had been grounded on Scriptural authority. All the strange vagaries in which the seventeenth century had been so fruitful claimed the voice of Scripture in their favour.
Such reckless use of Scripture tended to throw discredit upon it as a revelation from God; while, on the other hand, the grand discoveries in natural science which were a distinguishing feature of the seventeenth century equally tended to exalt men's notions of that other revelation of Himself which God has made in the Book of Nature. The calm attitude of the men of science who had been steadily advancing in the knowledge of the natural world, and by each fresh discovery had given fresh proofs of the power, and wisdom, and goodness of God, stood forth in painful contrast with the profitless wranglings and bitter animosities of Divines. Men might well begin to ask themselves whether they could not find rest from theological strife in natural religion? and the real object of the Deists was to demonstrate that they could.
