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.
