Christian Socialism - Catholic Criticisms

Catholic Criticisms

In Roman Catholicism, Socialism was strongly criticized in the 1878 papal encyclical Quod Apostolici Muneris by Pope Leo XIII. It was again denounced in the 1931 letter Quadragesimo Anno. Socialists were accused of attempting to overthrow all existing civil society, and Christian socialism was deemed to be an oxymoron because of this. Pius XI famously wrote at the time that "no one can be at the same time a good Catholic and a true socialist".

The encyclical Rerum Novarum encyclical of Pope Leo XIII from 1891 was the starting point of a teaching on social questions that was expanded and updated all through the 20th century. Despite the introduction of social thought as an object of religious thought, Rerum Novarum explicitly rejects what it calls "the main tenet of socialism":

"Hence, it is clear that the main tenet of socialism, community of goods, must be utterly rejected, since it only injures those whom it would seem meant to benefit, is directly contrary to the natural rights of mankind, and would introduce confusion and disorder into the commonwealth. The first and most fundamental principle, therefore, if one would undertake to alleviate the condition of the masses, must be the inviolability of private property." Rerum Novarum, paragraph 16
