"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. The "Ad Autolychum", the only extant writing of Theophilus, is an apology for Christianity. It consists of three books, really separate works written at different times, and corresponds exactly to the description given of it by Eusebius as "three elementary works". The author speaks of himself as a convert from heathenism. He treats of such subjects as the Christian idea of God, the Scripture accounts of the origin of man and the world as compared with pagan myths. On several occasions he refers (in connection with the early chapters of Genesis) to an historical work composed by himself.
