4. And how do they become the sons of God? “Who were born, not of blood, nor of the will of man, nor of the will of the flesh, but of God.” Having received power to become the sons of God, they are born of God. Mark then: They are born of God, “not of blood,” like their first birth, like that wretched birth, issuing out of wretchedness. But they who are born of God, what were they? whereby were they first born? Of blood; of the joint blood of the male and female, of the carnal union of male and female, from this were they born. From whence now? They are born of God. The first birth of the male and female; the second birth of God and the Church.
