This paper examines the manner in which the early modern scholarly debate concerning the true age of the world was shaped by philological and text-critical scholarship on the work of the first-century Jewish historian Flavius Josephus. Traditionally, historians have earmarked the late seventeenth century as a time of uncertainty and crisis for biblical chronologists, as scholars became increasingly aware of corruptions within existing versions of scripture and of the manner in which scriptural chronology was contradicted by pagan sources. I hope (...) to show how, in response to these doubts, scholars during this period also developed a pronounced interest in the chronology – and consequently the textual history – of the first-century Jewish historian Flavius Josephus, whom scholars considered the oldest and therefore best surviving witness to the original state of the biblical text in the time of the Apostles. I have drawn two important conclusions from this development. Firstly, I show that the development of philological and text-critical scholarship on non-biblical texts was a direct result of theological issues relating to biblical authority and chronology. Secondly, I argue that this philological scholarship was key to undermining orthodox faith in the stability and reliability of the biblical text itself. (shrink)
