"In the face of staggering problems which, from the human point of view, seem at times to be almost insoluble, people all over the world have found reason for renewed confidence and courage in the welcome thought that the Fathers of the Council, as Your Holiness indicated in your Radio Message of September 11, will give special attention to the grave economic and social problems which daily press upon suffering humanity in almost all parts of the world but, more particularly, in the economically underdeveloped nations. It is very heartening to know that the Council, in the words of Your Holiness, will strive to deepen the fellowship and love which are "the natural needs of man" and "are imposed on the Christian as rules for his relationship between man and man, and between people and people." We hope that the Council will be able to present in clear and persuasive language effective solutions to the many problems confronting all of us and, more specifically, that its decisions will significantly advance the cause of international peace and understanding."
