This [the opening of the Vatican City radio station built by Marconi earlier in 1931] was a new demonstration of the harmony between science and religion that each fresh conquest of science ever more luminously confirms, so that one may say that those who speak of the incompatibility of science and religion either make science say that which it never said or make religion say that which it never taught.

In the first place, it is obvious that not only is wealth concentrated in our times but an immense power and despotic economic dictatorship is consolidated in the hands of a few, who often are not owners but only the trustees and managing directors of invested funds which they administer according to their own arbitrary will and pleasure. This dictatorship is being most forcibly exercised by those who, since they hold the money and completely control it, control credit also and rule the lending of money.

Capitalism itself is not to be condemned. And surely it is not vicious of its very nature, but it has been vitiated.

Men will see in their king or in their rulers men like themselves perhaps unworthy or open to criticism, but they will not on that account refuse obedience if they see reflected in them the authority of Christ, God and Man. Peace and harmony, too, will result; for with the spread and the universal extension of the kingdom of Christ, men will become more and more conscious of the link that binds them together, and thus many conflicts will either be prevented entirely or at least their bitterness be diminished.

Those wretches tainted with the error of Indifferentism and Modernism hold that dogmatic truth is not absolute, but relative: that is, that it must adapt itself to the varying necessities of the times and the varying dispositions of souls, since it is not contained in an unchangeable revelation, but is, by its very nature, meant to accommodate itself to the life of man.

When once men recognize, both in private and in public life, that Christ is King, society will at last receive the great blessings of real liberty, well-ordered discipline, peace and harmony.

If Socialism, like all errors, contains some truth (which, moreover, the Supreme Pontiffs have never denied), it is based nevertheless on a theory of human society peculiar to itself and irreconcilable with true Christianity. Religious socialism, Christian socialism, are contradictory terms; no one can be at the same time a good Catholic and a true socialist.
