It was on the feast of St. Francis of Assisi that Pope Francis signed this encyclical letter, which he entitled “Fratelli tutti”, an expression in Italian taken from a writing of the Saint which was addressed “to all his brothers and sisters, to propose a way of life to them in keeping with the Gospel”. It is an “open fraternity that allows each person to be recognised, valued and loved…” that the Pope will talk about throughout the 216 pages of this encyclical.
