In his new encyclical "FRATELLI TUTTI", Pope Francis calls for a more fraternal society that does not just continue as before after the Corona crisis. What are the great ideals and the concretely practicable ways for those who want to build a more just and fraternal world in daily relationships, in society, in politics, in institutions? This is the question that "Fratelli tutti" intends to answer: the Pope defines it as a "social encyclical" which takes its title from the 'Admonitions' of St. Francis of Assisi, who used those words "to address all the brothers and sisters and offer them a form of life with the flavor of the Gospel ". The Encyclical aims to promote a universal aspiration toward fraternity and social friendship. In the background of the Encyclical is the Covid-19 pandemic which, Francis reveals, "unexpectedly erupted" as he "was writing this letter". But the global health emergency has helped demonstrate that "no one can face life in isolation" and that the time has truly come to "dream, then, as a single human family" in which we are "brothers and sisters all".
