Thus, the original and paradigmatic virginal generation is the divine generation itself.
This complete integrity is at the heart of what Gregory means by virginal generation. Its closest human analogue is Mary's birth-giving, occurring as it does without the participation of a human father, which would have involved her generation in incompleteness and division.
Mary's virginal generation is the closest material image of divine and immaterial generation, and it functions in turn as the human model for transformed spiritual generation.
This new mode of existence includes a kind of spiritual generation akin to the incorporeal modes of generation we have discussed and to Mary's virginal generation. It brings into being eternal life, and Gregory contrasts it strongly with ordinary human generation, which is confined to the material world of flux and decay and linked to death.
This discloses an essential difference between human virginal generation and that of God the Father.
