With the most famous work of Matthew Tindal, [743] Christianity as Old as Creation (1730), the excitement seems to have reached high-water mark. Here was vivacity without flippancy, and argument without irrelevant mirth; and the work elicited from first to last over a hundred and fifty replies, at home and abroad. Tindal's thesis is that the idea of a good God involved that of a simple, perfect, and universal religion, which must always have existed among mankind, and must have essentially consisted in moral conduct. Christianity, insofar as it is true, must therefore be a statement of this primordial religion; and moral reason must be the test, not tradition or Scripture. One of the first replies was the Vindication of Scripture by Waterland, to which Middleton promptly offered a biting retort in a Letter to Dr. Waterland (1731) that serves to show the slightness of its author's faith. After demolishing Waterland's case as calculated rather to arouse than to allay skepticism, he undertakes to offer a better reply of his own. It is to the simple effect that some religion is necessary to mankind in modern as in ancient times; that Christianity meets the need very well; and that to set up reason in its place is "impracticable" and "the attempt therefore foolish and irrational," in addition to being "criminal and immoral," when politically considered. [744] Such legalist criticism, if seriously meant, was hardly likely to discredit Tindal's book. Its directness and simplicity of appeal to what passed for theistic common-sense were indeed fitted to give it the widest audience yet won by any deist; and its anti-clericalism would carry it far among his fellow Whigs to begin with. [745] One tract of the period, dedicated to the Queen Regent, complains that "the present raging infidelity threatens an universal infection," and that it is not confined to the capital, but "is disseminated even to the confines of your kingdom." [746] Tindal, like Collins, wrote anonymously, and so escaped prosecution, dying in 1733, when the second part of his book, left ready for publication, was deliberately destroyed by Bishop Gibson, into whose hands it came. In 1736 he and Shaftesbury are described by an orthodox apologist as the "two oracles of deism." [747]
