That there is a God, then, is no matter of doubt to those who receive the Holy Scriptures, the Old Testament, I mean, and the New; nor indeed to most of the Greeks. For, as we said Supr.c. 1; cf. Greg. Naz., Orat. 34., the knowledge of the existence of God is implanted in us by nature. But since the wickedness of the Evil One has prevailed so mightily against man’s nature as even to drive some into denying the existence of God, that most foolish and woe-fulest pit of destruction (whose folly David, revealer of the Divine meaning, exposed when he said Ps. xiv. 1 (E.V.)., The fool said in his heart, There is no God), so the disciples of the Lord and His Apostles, made wise by the Holy Spirit and working wonders in His power and grace, took them captive in the net of miracles and drew them up out of the depths of ignorance The readings vary between ἀγνωσίας and ἀγνοίας. to the light of the knowledge of God. In like manner also their successors in grace and worth, both pastors and teachers, having received the enlightening grace of the Spirit, were wont, alike by the power of miracles and the word of grace, to enlighten those walking in darkness and to bring back the wanderers into the way. But as for us who Greg. Naz., Orat. 34. are not recipients either of the gift of miracles or the gift of teaching (for indeed we have rendered ourselves unworthy of these by our passion for pleasure), come, let us in connection with this theme discuss a few of those things which have been delivered to us on this subject by the expounders of grace, calling on the Father, the Son, and the Holy Spirit.
