Abstract
This article presents a detailed exposition of Celsus’ criticism for Christianity, for the first time in Spanish. Celsus was the first known philosopher in Antiquity, who lashed against the dawning Christianity from the point of view of the Greek tradition, the Alethes Logos. The paper shows, first, the metaphysical and philosophical perspective of Celsus’ criticism. Secondly, it brings us inside the ethical and political stirs of Christianity, from Celsus’ own point of view and how this has affected his civil world. This criticism marks the starting point of a philosophical vindication of European paganism, with Giordiano Bruno and Friedrich Nietzsche as its greatest advocates
