This text will show the deep differences (for example transcendent reasoning of Christian conscience) and also an interesting consensus (above all the importance of the connection between the freedom of human beings and understanding of truth) between the Christianity and the Marxism. This is the reason, why this thesis emphasises the danger of false comprehension or disuse of Christian requirements on human beings (person) in terms of totalitarian ideology, but also stimuli which makes possible dialogue also with contemporary people, who are very conscious of their freedom of conscience and revolt against any form of totality.
