The present study, for the first time, provides a comparative analysis of the objections raised against Christianity by late antique pagan philosophers (esp. Celsus in Alethes logos, Porphyry in Contra Christianos, and Julian the Apostate in Contra Gali-laeos) and Enlightenment philosophers and freethinkers and examines the impact of pagan thinking on the critique of Christianity in the 16th to 18th centuries – in particular, on discussions concerning the authority of the Bible, biblical exegesis, the Christian concept of faith, religious coercion and the uniformity of faith, the belief in miracles, and the Christ-ian understanding of morality.
