The above is from Pope Paul VI's address to the United Nations General Assembly, October 4, 1965.
Here's another excerpt from the same address:
The peoples of the earth turn to the United Nations as the last hope of concord and peace. We presume to present here, together with Our own, their tribute to honour and of hope. That is why this moment is a great one for you also. We know that you are fully aware of this. Now for the continuation of Our message. It looks entirely towards the future. The edifice which you have constructed must never collapse; it must be continually perfected and adapted to the needs which the history of the world will present. You mark a stage in the development of mankind; from now on retreat is impossible; you must go forward.
You'll happily accept the writing presented in post #75 because it comes from the pen of Leo XIII (paragraph #3 from the encyclical Rerum Novarum for those wondering).
If Francis had written the same lines you'd have a conniption fit.
True?
