Among the arguments presented as follows:
1) Christ was conceived by the Virgin Mary. Could this have been a natural event, parthenogenesis (virgin birth)? If this was a natural event, Mary would have given birth to a girl because she could only contribute the female sex gene. In Mary's case, however, a man was conceived which involved the miraculous intervention of God. Therefore, man could not say that this was parthenogenesis, a natural event.
2) God wanted to involve both man and woman in his saving plan. If God had chosen as a savior a woman, mankind would have had a Virgin Mother and a Divine Daughter. Man's nature would have been completely bypassed.
