I'll admit that your contribution tips me towards being a bit more wary; I had quit readin the 124 page document when I though I had found the relevant sections. Mea Culpa. But, gee, what are some of those things you are omitting in your ellipses? "Such an authority would need to be regulated by law, to observe consistently the principles of subsidiarity and solidarity, to seek to establish the common good." "Subsidiarity" is the principle that authority must lie in the individual, or the smallest unit of governance or control possible. "Regulated by law," the pope explained previously, means that the nations of the Earth must consent and ratify democratically the actions of the body.
A humanism which excludes God is an inhuman humanism.
“But, gee, what are some of those things you are omitting in your ellipses? “Such an authority would need to be regulated by law, to observe consistently the principles of subsidiarity and solidarity, to seek to establish the common good.””
I cut out what I considered to be portions not directly related to a world authority. No malice intended.
