Love is a gift of God, nourished by and expressed in the encounter of man and woman. Love is thus a positive force directed towards their growth towards maturity as persons. In the plan of life which represents each person's vocation, love is also a precious source for the self-giving which all men and women are called to make for their own self-realization and happiness. In fact, man is called to love as an incarnate spirit, that is soul and body in the unity of the person. Human love hence embraces the body, and the body also expresses spiritual love. Therefore, sexuality is not something purely biological, rather it concerns the intimate nucleus of the person. The use of sexuality as physical giving has its own truth and reaches its full meaning when it expresses the personal giving of man and woman even unto death. As with the whole of the person's life, love is exposed to the frailty brought about by original sin, a frailty experienced today in many socio-cultural contexts marked by strong negative influences, at times deviant and traumatic.
Basically, education for authentic love, authentic only if it becomes kind, well-disposed love, involves accepting the person who is loved and considering his or her good as one's own; hence this implies educating in right relationships with others. Children, adolescents and young people should be taught how to enter into healthy relationships with God, with their parents, their brothers and sisters, with their companions of the same or the opposite sex, and with adults.
It must also not be forgotten that education in love is an overall reality. There will be no progress in setting up proper relationships with one person if at the same time there are no proper relationships with other people.
