According to Nietzsche, the history of the West faced a very peculiar phenomenon that influenced all posterity: the advent of Christianity. From the moment that the Christian religion became institutionalized, a way of living and creating moral values came into force, geared to Christian teachings.
It is important to emphasize that Nietzsche, at no time, criticized Jesus Christ, but rather what they did of Christianity from the moment when the life of Jesus becomes a foundation for a religion, that is, from the apostles Paul, Peter and the foundation of the Catholic Church. Nietzsche asserted that Christianity, imperative from the Middle Ages onwards, imposed an inversion of moral values that would culminate in the weakening of the human being, as it is the negation of the moral impulses that speak louder in any animal. Controversial statements such as "Christianity is the revolt of everything that crawls on the ground against what is high" condense Nietzschean thought.
