In Pope Pius XI's encyclical, DIVINI ILLIUS MAGISTRI, on Christian Education, we find precious insights about education, with a special comment on the evil effects of theories of advanced Socialism.
“Nevertheless, Venerable Brethren and beloved children, We wish to call your attention in a special manner to the present-day lamentable decline in family education. The offices and professions of a transitory and earthly life, which are certainly of far less importance, are prepared for by long and careful study; whereas for the fundamental duty and obligation of educating their children, many parents have little or no preparation, immersed as they are in temporal cares.
“The declining influence of domestic environment is further weakened by another tendency, prevalent almost everywhere today, which, under one pretext or another, for economic reasons, or for reasons of industry, trade or politics, causes children to be more and more frequently sent away from home even in their tenderest years.
“And there is a country where the children are actually being torn from the bosom of the family, to be formed (or, to speak more accurately, to be deformed and depraved) in godless schools and associations, to irreligion and hatred, according to the theories of advanced socialism; and thus is renewed in a real and more terrible manner the slaughter of the Innocents.”
