12 Above all, We wish you to direct your zeal and devotion towards the education of children and adolescents. It is not Our intention to repeat now what We have already written in the same letter that We mentioned in the beginning of this one. We cannot, however, refrain from touching briefly upon certain serious matters. In respect to primary schools, you must insist that pastors and others who are in charge of souls be constantly vigilant in their behalf and consider it their most important duty to teach sacred doctrine to children. This special service should be undertaken by themselves and valued as a sacred trust. It is certain that a wholesome and pious education in childhood ensures in great measure not only the preservation of the family, but of the state itself. Nor should you spare any industry or ingenuity to help these schools increase and develop successfully. It would be most appropriate to appoint in each diocese supervisors of schools for both the diocese and the deaneries. The bishops could confer with them annually on the condition of the schools as well as on other matters pertaining to faith, morals, and the care of souls. If it should be necessary to build new schools in answer to local needs or enlarge those already established, we are fully confident that your liberality and likewise that of all Catholics will be prompt and generous.
