Fulton Sheen's speech outlines two main principles of activism from a Marxist perspective: first, the alienation of man due to private property and religion, which he argues must be abolished to restore man's dignity. Second, the insignificance of the individual compared to the group, as reflected in Marxist-influenced policies that prioritize the party over individual freedoms. He notes Marxism's gradual influence on the church, shifting focus from personal sins to societal engagement.
