Book excerpt: Following the publication of the Directory for Catechesis, Pope Francis is sending the Church a new Apostolic Letter in the form of a "motu proprio" establishing the ministry of the catechist. It is a very important step that recognizes the presence and importance of women and men who, thanks to their baptism, are called to a fundamental role in communicating faith, and educating children, young people and adults to it. The role of catechist will no longer be simply a parish assignment but a real Church ministry. It is an inspirational text for the delicate mission entrusted to catechists, that must be made available to every one of them.
