Especially noteworthy is Matthew Tindal's "Christianity as Old as the Creation" (1730), which "became, very soon after its publication, the focal center of the deist controversy. Because almost every argument, quotation, and issue raised for decades can be found here, the work is often termed 'the deist's Bible'." Following Locke's successful attack on innate ideas, Tindal's 'Bible' redefined the foundation of deist epistemology as knowledge based on experience or human reason. This effectively widened the gap between traditional Christians and what he called "Christian Deists", since this new foundation required that "revealed" truth be validated through human reason.
