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.
Thus the period of Deism was the period of a great religious crisis in England. It is our present purpose briefly to trace the progress and termination of this crisis.
It is hardly necessary to remark that Deism was not a product of the eighteenth century. The spirit in which Deism appeared in its most pronounced form had been growing for many generations previous to that date. But we must pass over the earlier Deists, of whom the most notable was Lord Herbert of Cherbury, and come at once to a writer who, although his most notorious work was published before the seventeenth century closed, lived and wrote during the eighteenth, and may fairly be regarded as belonging to that era.
No work which can be properly called Deistical had raised anything like the excitement which was caused by the anonymous publication in 1696 of a short and incomplete treatise entitled 'Christianity not Mysterious, or a Discourse showing that there is nothing in the Gospel contrary to Reason nor above it, and that no Christian Doctrine can properly be called a Mystery.' In the second edition, published the same year, the author discovered himself to be a young Irishman of the name of John Toland, who had been brought up a Roman Catholic. Leland passes over this work with a slight notice; but it marked a distinct epoch in Deistical literature. For the first time, the secular arm was brought to bear upon a writer of this school. The book was presented by the Grand Jury of Middlesex, and was burnt by the hands of the hangman in Dublin by order of the Irish House of Commons. It was subsequently condemned as heretical and impious by the Lower House of Convocation, which body felt itself bitterly aggrieved when the Upper House refused to confirm the sentence. These official censures were a reflex of the opinions expressed out of doors. Pulpits rang with denunciations and confutations of the new heretic, especially in his own country. A sermon against him was 'as much expected as if it had been prescribed in the rubric;' an Irish peer gave it as a reason why he had ceased to attend church that once he heard something there about his Saviour Jesus Christ, but now all the discourse was about one John Toland.[148]
Toland being a vain man rather enjoyed this notoriety than otherwise; but if his own account of the object of his publication be correct (and there is no reason to doubt his sincerity), he was singularly unsuccessful in impressing his real meaning upon his contemporaries. He affirmed that 'he wrote his book to defend Christianity, and prayed that God would give him grace to vindicate religion,' and at a later period he published his creed in terms that would satisfy the most orthodox Christian.
For an explanation of the extraordinary discrepancy between the avowed object of the writer and the alleged tendency of his book we naturally turn to the work itself. After stating the conflicting views of divines about the Gospel mysteries, the author maintains that there is nothing in the Gospel contrary to reason nor above it, and that no Christian doctrine can be properly called a mystery. He then defines the functions of reason, and proceeds to controvert the two following positions, (1) that though reason and the Gospel are not in themselves contradictory, yet according to our conception of them they may seem directly to clash; and (2) that we are to adore what we cannot comprehend. He declares that what Infinite Goodness has not been pleased to reveal to us, we are either sufficiently capable of discovering ourselves or need not understand at all. He affirms that 'mystery' in the New Testament is never put for anything inconceivable in itself or not to be judged by our ordinary faculties; and concludes by showing that mysteries in the present sense of the term were imported into Christianity partly by Judaisers, but mainly by the heathen introducing their old mysteries into Christianity when they were converted.
The stir which this small work created, marks a new phase in the history of Deism. Compared with Lord Herbert's elaborate treatises, it is an utterly insignificant work; but the excitement caused by Lord Herbert's books was as nothing when compared with that which Toland's fragment raised. The explanation may perhaps be found in the fact that at the later date men's minds were more at leisure to consider the questions raised than they were at the earlier, and also that they perceived, or fancied they perceived, more clearly the drift of such speculations. A little tract, published towards the end of the seventeenth century, entitled 'The Growth of Deism,' brings out these points; and as a matter of fact we find that for the next half century the minds of all classes were on the alert—some in sympathy with, many more in bitter antagonism against Deistical speculations. In his later writings, Toland went much further in the direction of infidelity, if not of absolute Atheism, than he did in his first work.
