Notre Charge Apostolique - Pope St. Pius X, 25 August 1910

"We fear that worse is to come: the end result of this developing promiscuousness, the beneficiary of this cosmopolitan social action, can only be a Democracy which will be neither Catholic, nor Protestant, nor Jewish. It will be a religion (for Sillonism*, so the leaders have said, is a religion) more universal than the Catholic Church, uniting all men become brothers and comrades at last in the “Kingdom of God”. – “We do not work for the Church, we work for mankind.” And now, overwhelmed with the deepest sadness, We ask Ourselves, Venerable Brethren, what has become of the Catholicism of the Sillon*? Alas! this organization which formerly afforded such promising expectations, this limpid and impetuous stream, has been harnessed in its course by the modern enemies of the Church, and is now no more than a miserable affluent of the great movement of apostasy being organized in every country for the establishment of a One-World Church which shall have neither dogmas, nor hierarchy, neither discipline for the mind, nor curb for the passions, and which, under the pretext of freedom and human dignity, would bring back to the world (if such a Church could overcome) the reign of legalized cunning and force, and the oppression of the weak, and of all those who toil and suffer." - Pope Pius X
*Sillonism / Le Sillon was a French subversive movement to bring Catholicism into a greater conformity with French Republican Socialism
