The word "Eucharist" means literally "act of thanksgiving." To celebrate the Eucharist and to live a Eucharistic life has everything to do with gratitude. Living Eucharistically is living life as a gift, a gift for which one is grateful. But gratitude is not the most obvious response to life, certainly not when we experience life as a series of losses! Still, the great mystery we celebrate in the Eucharist and live in a Eucharistic life is precisely that through mourning our losses we come to know life as a gift.
