The Salesians of Don Bosco, formally known as the Society of St. Francis of Sales, are recognized in the Church as a clerical religious institute of pontifical right, "dedicated to apostolic works". They are a Religious Congregation of men devoted to apostolic and missionary activity and to the many different works inspired by Christian charity, but especially the service of young people, in particular, those who are poorer and disadvantaged.
This is the root of the Salesian Family, as their leader, the Rector Major, is the successor of St. John Bosco, and thus the Father of the whole Salesian Family.
