33 Great, indeed, is the work; but in it the clergy will share your labours, if, through your care, they are fitted for it by learning and a well-turned life. This good and great work requires to be helped also by the industry of those amongst the laity in whom a love of religion and of country is joined to learning and goodness of life. By uniting the efforts of both clergy and laity, strive, venerable brethren, to make men thoroughly know and love the Church; for, the greater their knowledge and love of the Church, the more will they be turned away from clandestine societies.
