Abstract
From the above lines one can see that St. Cyril of Alexandria is presented, along with a great theologian, as it is clear from the writings against the heretics of his time, like a true apologist for Christianity with paganism dispute that resurfaced after Emperor Julian, the Apostate. On the other hand, the writing of the Orthodox Patriarch proves to be of great importance in understanding the difficulties experienced by the Christian faith in a territory where paganism flourished from time to time. Moreover, the work of St. Cyril can be put together with Christian apologists ‗works from previous centuries, being of a real interest for our times into a field so necessary but forgot in the theological schools and pastoral work: Apologetics.
