Cooperators are Catholics who, while living their faith within the framework of their own secular condition, draw their ispiration from Don Bosco’s apostolic project, To contribute to the salvation of the young, “that part of human society which is so exposed and yet so rich in promise”. The lay Cooperators fulfil their commitment and live the Salesian spirit in the normal situations of their life and work, according to their lay state, and spread their values in their environment.
