Christianity

Since the third century Christianity has always served simultaneously those who supported the social order and those who wished to overthrow it. . . . It is the same today: Christianity fights both for and against Socialism.

Socialism, p. 378

It was not the Syllabus of Pope Pius IX that paved the way for the return of intolerance and the persecution of dissenters. It was the writings of the socialists.

Theory and History, p. 68

Christian Socialism is none the less Socialism.

Socialism, p. 382

Socialism, pp. 397–98

Virtually all the Christian churches and sects have espoused the principles of socialism and interventionism. In almost every country the clergy favor nationalism. In spite of the fact that Catholicism is world embracing, even the Roman Church offers no exception. The nationalism of the Irish, the Poles, and the Slovaks is to a great extent an achievement of the clergy. French nationalism found most effective support in the Church.

Protestantism is no more a safeguard of freedom than Catholicism. The ideal of liberalism is the complete separation of church and state, and tolerance—without any regard to differences among the churches.
