38. In the task of development man finds the family to be the first and most basic social structure; but he is often helped by professional organizations. While such organizations are founded to aid and assist their members, they bear a heavy responsibility for the task of education which they can and must carry out. In training and developing individual men, they do much to cultivate in them an awareness of the common good and of its demands upon all.
39. Every form of social action involves some doctrine; and the Christian rejects that which is based on a materialistic and atheistic philosophy, namely one which shows no respect for a religious outlook on life, for freedom or human dignity. So long as these higher values are preserved intact, however, the existence of a variety of professional organizations and trade unions is permissible. Variety may even help to preserve freedom and create friendly rivalry. We gladly commend those people who unselfishly serve their brothers by working in such organizations.
