That does not mean that we must renounce this science or deprive ourselves of its results. On the contrary, it can teach us something about the education of man, in his masculinity and femininity, and about the sphere of marriage and procreation. It is precisely at this point that reflection on the ancient text of Genesis is irreplaceable. It is the beginning of the theology of the body. The fact that theology also considers the body should not astonish or surprise anyone who is aware of the mystery and reality of the Incarnation.
Theology is that science whose subject is divinity.
Through the fact that the Word of God became flesh, the body entered theology through the main door. The Incarnation and the redemption that springs from it became also the definitive source of the sacramentality of marriage, which we will deal with at greater length in due time. The questions raised by modern man are also those of Christians - those who are preparing for the sacrament of marriage or those who are already living in marriage, which is the sacrament of the Church. These are not only the questions of science, but even more, the questions of human life. So many men and so many Christians seek the accomplishment of their vocation in marriage.
