John Craig’s book Theologiae Christianae Principia Mathematica (Mathematical Principles of Christian Theology) infuriated contemporaries when it appeared in 1699. Modern scholars also express reservations about the contents. Many read the work in association with Isaac Newton and view Craig’s calculation for the Second Coming in 3150 with bemusement and condescension. Historians of statistics give the book a fairer reading, but often they look to assess the closeness of Craig’s calculations to modern mathematics. In this article, I aim to situate Craig (...) and his book as part of the deist controversy. My goal is to illustrate that the perceived danger of deism in the later seventeenth century was such that it influenced the content of a variety of discourses and that Craig’s work is representative of a moment in which apocalyptic anticipations and anxiety over deism could mix freely with mathematics and conceptions of the historical record in a presentation reminiscent of Isaac Newton’s Principia.
