As a follow up to my recent musings on the firing of the Google engineer for pointing out some basic differences between men and women, I came across this quotation from Pope John Paul II, from his 1994 Letter to Families, Gratissimam Sane, for a more theological take on this most fundamental and rather obvious matter:
In the light of the New Testament it is possible to discern how the primordial model of the family is to be sought in God himself, in the Trinitarian mystery of his life. The divine “We” is the eternal pattern of the human “we”, especially of that “we” formed by the man and the woman created in the divine image and likeness. The words of the Book of Genesis contain that truth about man which is confirmed by the very experience of humanity. Man is created “from the very beginning” as male and female: the life of all humanity —whether of small communities or of society as a whole—is marked by this primordial duality. From it there derive the “masculinity” and the “femininity” of individuals, just as from it every community draws its own unique richness in the mutual fulfilment of persons. This is what seems to be meant by the words of the Book of Genesis: “Male and female he created them” (Gen 1:27). Here too we find the first statement of the equal dignity of man and woman: both, in equal measure, are persons. Their constitution, with the specific dignity which derives from it, defines “from the beginning” the qualities of the common good of humanity, in every dimension and circumstance of life. To this common good both man and woman make their specific contribution. Hence one can discover, at the very origins of human society, the qualities of communion and of complementarity.
