Establishing universal worldwide authority

Today the universal common good poses problems of worldwide dimensions, which cannot be adequately tackled or solved except by the efforts of public authority endowed with a wideness of powers, structure and means of the same proportions: that is, of public authority which is in a position to operate in an effective manner on a world-wide basis. The moral order itself, therefore, demands that such a form of public authority be established. This public authority, having world-wide power and endowed with the proper means for the efficacious pursuit of its objective, which is the universal common good in concrete form, must be set up by common accord and not imposed by force. The reason is that such an authority must be in a position to operate effectively; yet, at the same time, its action must be inspired by sincere and real impartiality: it must be an action aimed at satisfying the universal common good. The difficulty is that there would be reason to fear that a supra-national or worldwide public authority, imposed by force by the more powerful nations might be an instrument of one-sided interests; and even should this not happen, it would be difficult for it to avoid all suspicion of partiality in its actions, and this would take from the force and effectiveness of its activity. Even though there may be pronounced differences between nations as regards the degree of their economic development and their military power, they are all very sensitive as regards their juridical equality and the excellence of their way of life. For that reason, they are right in not easily yielding obedience to an authority imposed by force, or to an authority in whose creation they had no part, or to which they themselves did not decide to submit by their own free choice. ."
