“This mutual gift of the person in marriage opens to the gift of a new life, a new human being, who is also a person in the likeness of his parents. Motherhood implies from the beginning a special openness to the new person: and this is precisely the woman’s “part”. In this openness, in conceiving and giving birth to a child, the woman “discovers herself through a sincere gift of self”. The gift of interior readiness to accept the child and bring it into the world is linked to the marriage union, which – as mentioned earlier – should constitute a special moment in the mutual self-giving both by the woman and the man. According to the Bible, the conception and birth of a new human being are accompanied by the following words of the woman: “I have brought a man into being with the help of the Lord” (Gen 4:1).This exclamation of Eve, the “mother of all the living” is repeated every time a new human being comes into the world. It expresses the woman’s joy and awareness that she is sharing in the great mystery of eternal generation. The spouses share in the creative power of God!
“The woman’s motherhood in the period between the baby’s conception and birth is a bio-physiological and psychological process which is better understood in our days than in the past, and is the subject of many detailed studies. Scientific analysis fully confirms that the very physical constitution of women is naturally disposed to motherhood – conception, pregnancy and giving birth – which is a consequence of the marriage union with the man. At the same time, this also corresponds to the psycho-physical structure of women. What the different branches of science have to say on this subject is important and useful, provided that it is not limited to an exclusively bio-physiological interpretation of women and of motherhood. Such a “restricted” picture would go hand in hand with a materialistic concept of the human being and of the world. In such a case, what is truly essential would unfortunately be lost. Motherhood as a human fact and phenomenon, is fully explained on the basis of the truth about the person. Motherhood is linked to the personal structure of the woman and to the personal dimension of the gift: “I have brought a man into being with the help of the Lord” (Gen 4:1). The Creator grants the parents the gift of a child. On the woman’s part, this fact is linked in a special way to “a sincere gift of self”. Mary’s words at the Annunciation – “Let it be to me according to your word” – signify the woman’s readiness for the gift of self and her readiness to accept a new life.”
