"The miracle that saves the world, the realm of human affairs, from its normal "natural" ruin is ultimately the fact of natality, in which the faculty of action is ontologically rooted. It is, in other words, the birth of new men and the new beginning, the action they are capable of by virtue of being born. Only the full experience of this capacity can bestow upon human affairs faith and hope, those two essential characteristics of human existence which Greek antiquity ignored altogether, discounting the keeping of faith as a very uncommon and not too important virtue and counting hope among the evils of illusion in Pandora's box. It is this faith in and hope for the world that found perhaps its most glorious and most succinct expression in the few words with which the Gospels announced their 'glad tidings':"A child has been born unto us."
Who? Where? When? Took me aback in finding it.
