78. If, then, the common order of human generation was not found in the case of the Virgin Mary, how can you demand that God the Father should beget in such wise as you were begotten in? Surely the common order is determined by difference of sex; for this is implanted in the nature of our flesh, but where flesh is not, how can you expect to find the infirmity of flesh? No man calls in question one who is better than he is: to believe is enjoined upon you, without permission to question. For it is written, “Abraham believed God, and it was accounted to him for righteousness.” Gen. xv. 6. Language is vain to set forth, not only the generation of the Son, but even the works of God, for it is written: “All His works are executed in faithfulness;” Ps. xxxiii. 4. His works, then, are done in faithfulness, but not His generation? Ay, we call in question that which we see not, we who are bidden to believe rather than enquire of that we see.
