argue that a difference in bodies constitutes a difference in spirit, that the soul is not unisex. Stein's argument has been criticized for not realizing that the immateriality of the human soul transcends the limitations of the body as Aquinas argues. New feminist theories were also influenced by the Personalist and Phenomenology movements of the early 20th century. Integral complementarity differs from fractional complementarity, in that it argues that men and women are each whole persons in and of themselves, and, together, equal more than the sum of their parts. The concept of fractional complementarity argues that a man and woman each make up a part of a person. By this theory, when they are joined together, they then comprise one, composite being. Meaning of the body New feminists promote an understanding of the human person as one who is made in the image and likeness of God (imago Dei) for the purpose of union and communion. They see distinct differences in the ways in which men and women make a sincere gift of themselves through the 'nuptial meaning of the body', and see these gifts as shedding light on the mysteries of God and their own vocation, mission and dignity. Other ideas promoted by new feminists include: that the different bodily structures of men and women lead both to different lived experiences. that the different ways in which men and women give life physically are linked to emotional, spiritual, and intellectual dispositions. that fulfillment as a woman means exercising maternal care, whether physically or spiritually. New feminists believe that whether or not they do it well, women are physically structured to be mothers, to develop life with their wombs. They purport the idea that the physical capacity for motherhood connects with the psychological, spiritual and emotional characteristics that women would need to be mothers. that regardless of whether or not a woman ever gives birth, she has the capacity for maternal love in spiritual motherhood. The feminine genius The phrase "the feminine genius" is used to describe the genius that John Paul II identified as belonging to women, “which can ensure sensitivity for human beings in every circumstance.” He argues that this sensitivity is linked to maternity. Work on unpacking the nature of this link can be found in various anthologies, such as Women in Christ: Toward a New Feminism (2004) and Woman as Prophet in the Home and
