"Furthermore, such an authority would need to be universally recognized and to be vested with the effective power to ensure security for all, regard for justice, and respect for rights[148]. Obviously it would have to have the authority to ensure compliance with its decisions from all parties, and also with the coordinated measures adopted in various international forums."
In effect, a one world government. Forgive me if I don't enlist...
Without this, despite the great progress accomplished in various sectors, international law would risk being conditioned by the balance of power among the strongest nations. The integral development of peoples and international cooperation require the establishment of a greater degree of international ordering, marked by subsidiarity, for the management of globalization[149]. They also require the construction of a social order that at last conforms to the moral order, to the interconnection between moral and social spheres, and to the link between politics and the economic and civil spheres...
You could construe it that way but if it respects the principles of subsidiarity, it can't be.
Furthermore, the Pope states that it would need to be "universally recognized". That's not a "top down" one world government. It's a "bottom up" structure which depends for its mandate on a common consensus in agreement with the rule of law. The clear implication is that without the "universal recognition" the body has no authority.
Thus, he's not calling for the imposition of a socialist dictatorship. He's calling first and foremost for a solidarity among peoples which leads in turn to the recognition of universal human rights based on natural law.
Here's the good news, however. You won't have to enlist. This will never happen.
Nobody listens to the Pope. Not even Catholics.
