Denying human transcendence

The Christian who wishes to live his faith in a political activity which he thinks of as service cannot without contradicting himself adhere to ideological systems which radically or substantially go against his faith and his concept of man. He cannot adhere to the Marxist ideology, to its atheistic materialism, to its dialectic of violence and to the way it absorbs individual freedom in the collectivity, at the same time denying all transcendence to man and his personal and collective history. (Papal Writings, 14 May 1971).
