Experience teaches us that love must find its safeguard in the stability of marriage, if sexual intercourse is truly to respond to the requirements of its own finality and to those of human dignity. These requirements call for a conjugal contract sanctioned and guaranteed by society - a contract which establishes a state of life of capital importance both for the exclusive union of the man and the woman and for the good of their family and of the human community. Most often, in fact, premarital relations exclude the possibility of children. What is represented to be conjugal love is not able, as it absolutely should be, to develop into paternal and maternal love. Or, if it does happen to do so, this will be to the detriment of the children, who will be deprived of the stable environment in which they ought to develop in order to find in it the way and the means of their insertion into society as a whole.
