The world situation, in which violence is at work under different forms, impels Christians to study, to refine and to make better known the natural methods for mastering fertility. These have the immense advantage of being less "aggressive" and less exacting on the woman. Consequently, they respect better the spouses' harmony. Moreover, they predispose couples to exercise their responsible freedom in political and economic society.
These natural methods, too often misunderstood and discredited, have, besides, proven their ability to effectively reduce population growth exactly where the problem arises. Mother Teresa received from Rajiv Gandhi one of the highest distinctions of India because, in Calcutta, she had succeeded where the technicians of "modern contraception" had failed.
