The Sacred Writings of Tatian [EPUB ebook] 

‘The Sacred Writings Of …’ provides you with the essential works among the Early Christian writings. The volumes cover the beginning of Christianity until before the promulgation of the Nicene Creed at the First Council of Nicaea.
Besides fragments from other works, this vlume contains the ‘Oratio ad Graecos’ (Pros Hellenas), an apology for Christianity, containing in the first part (i-xxxi) an exposition of the Christian Faith with a view to showing its superiority over Greek philosophy, and in the second part a demonstration of the high antiquity of the Christian religion. The tone of this apology is bitter and denunciatory. The author inveighs against Hellenism in all its forms and expresses the deepest contempt for Greek philosophy and Greek manners.
