Moreover, since he frequently calls the Christian doctrine a secret system (of belief), we must confute him on this point also, since almost the entire world is better acquainted with what Christians preach than with the favourite opinions of philosophers. For who is ignorant of the statement that Jesus was born of a virgin, and that He was crucified, and that His resurrection is an article of faith among many, and that a general judgment is announced to come, in which the wicked are to be punished according to their deserts, and the righteous to be duly rewarded? And yet the mystery of the resurrection, not being understood, is made a subject of ridicule among unbelievers. In these circumstances, to speak of the Christian doctrine as a secret system, is altogether absurd.
