Resumen:
Charles Moeller is known for his great work 20th Century Literature and Christianity in 6 volumes. In this article we study his first works (especially Humanism and Holiness) where he develops his idea of Christian humanism in implicit dialogue with Nietzsche: to the figure of superman, Moeller contrasts the figure of the saint as that man who transcends the merely human, thus overcoming the vision of Greek humanism that aspires only to obtain what can be achieved by human forces.
