Great article, thanks to you Turbamulta. Reputation Points coming soon. However I have to clarify something regarding Rerum Novarum by Papa Leone XIII.
In the article it is said that the Pope said:
“peace and order; and the whole of domestic society to be governed by God’s Commandments and the principles of Natural Law; and to keep and promote religion; to flourish in private and public life pure habits and customs; to keep Justice unharmed; not to let without punishment the one who violates other’s right; to make strong citizens capable of helping other human beings, and if necessary, capable of defending society.”
While in Rerum Novarum Papa Leone XIII says according to Vatican.va:
"peace and good order should be maintained; that all things should be carried on in accordance with God's laws and those of nature; that the discipline of family life should be observed and that religion should be obeyed; that a high standard of morality should prevail, both in public and private life; that justice should be held sacred and that no one should injure another with impunity; that the members of the commonwealth should grow up to man's estate strong and robust, and capable, if need be, of guarding and defending their country."

Notwithstanding this, that was a great article, if you have more of them I'd appreciate if you posted them.
