80 Our dialogue, therefore, presupposes that there exists in us a state of mind which we wish to communicate and to foster in those around us. It is the state of mind which characterizes the man who realizes the seriousness of the apostolic mission and who sees his own salvation as inseparable from the salvation of others. His constant endeavor is to get everyone talking about the message which it has been given to him to communicate.
