The origin of the Don Bosco Past Pupils' Association is to be sought in the Preventive System, based as it is on the supernatural love of Don Bosco for the young. The pupils felt themselves loved by Don Bosco, not merely as pupils, but as sons, and consequently felt the need to return to their father's house on his feast day on June 24, 1870. Henceforth, under the leadership of Charles Gastini, it became an annual affair and the beginning of the association of past pupils.
The members of the Past Pupils’ Association are persons who, because they attended a Salesian school, training centre, tertiary institution, oratory or another Salesian presence, received a preparation for life, based on the principles of Don Bosco’s Preventive System: reason, religion and loving-kindness. Enriched by their formation to be ‘good Christians and honest citizens’ as well as by the charism of Don Bosco, they bear witnesses in their daily life to the Salesian education they have received.
