3 For We are convinced that the Rosary, if devoutly used, is bound to benefit not only the individual but society at large. No one will do Us the injustice to deny that in the discharge of the duties of the Supreme Apostolate We have laboured - as, God helping, We shall ever continue to labour - to promote the civil prosperity of mankind. Repeatedly have We admonished those who are invested with sovereign power that they should neither make nor execute laws except in conformity with the equity of the Divine mind. On the other hand, we have constantly besought citizens who were conspicuous by genius, industry, family, or fortune, to join together in common counsel and action to safeguard and to promote whatever would tend to the strength and well-being of the community. Only too many causes are at work, in the present condition of things, to loosen the bonds of public order, and to withdraw the people from sound principles of life and conduct.
