The Protestant apologists of the Romantic period were faced with the necessity of having to update their methodology to meet the constraints imposed by the explosive rise of an atheism that was becoming increasingly difficult to overcome. In departure from the overwhelming subjectivist tide which drew inspiration from Schleiermacher and made internal proof (i.e., Christianity as a perfect match for the innate needs of the human soul) the fundamental apologetic tool, the proponents of classic apologetics responded by charging that the views of their opponents would issue in the definitive dissolution of faith. The latter included Prosper Jalaguier, professor at the faculty of theology at Montauban, and one of the first in France to defend the supremacy of the demonstration of the truth of the Christian faith by external proof (i.e., historical arguments, miracles, and prophecy).
