From a re-evangelization of society can derive a new humanism and a renewed commitment and cultural design. It helps dethrone the modern idols, to replace individualism, consumerism and materialistic technocracy, with the culture of brotherhood and benevolence, love. Jesus Christ summed up and carrying out the precepts given in a new commandment: "as I have loved you, so you also love each other" (Jn. 13.34); Here lies the secret of all social life fully human and peaceful, as well as the renewal of politics and national and international institutions. Blessed Pope John XXIII motivated commitment to building a world community, with a corresponding authority, just moving out of love, out of love for the common good of the human family. Thus we read in Pacem in terris, "there is an intrinsic relationship between the historical content of the common good and the configuration of public authorities on the other. The moral order, i.e., as requires the public authority in partnership to implement the common good therefore demands that the authority to do so is efficient "(No. 71).

The Church has not tasked to suggest, from a legal point of view and political concrete configuration of such an international system, but offers to those who have responsibility for those principles of reflection, judgment criteria and practical guidelines that can ensure its anthropological and ethical frame around the common good (see Enc. Caritas in veritate, 67). On reflection, however, is to note that you shouldn't imagine a superpower, concentrated in the hands of a few, that would dominate on all Nations, by harnessing the weakest, but that any authority must be understood above all as a moral force, may have a second reason (cf. Pacem in terris, 27), i.e. as related authorities, accrual and limited by law.
