Quadragesimo Anno

...the riches that economic-social developments constantly increase ought to be so distributed among individual persons and classes that ... the common good of all society will be kept inviolate.

Pope Pius XI, 1931

After Forty Years

Writing in response to the alarming concentration of wealth and power in the socio-economic realm, Pius XI calls for the reestablishment of a social order based on the principle of subsidiarity. In commemorating the 40th anniversary of Rerum Novarum, this encyclical reaffirms the need for a social order animated by justice.
