Bishop Conlon Talks about the Declaration on Christian Education ("Gravissim Educationis"), part 8

The Church has a grave obligation to the moral education of all children - even those who go to non-Catholic schools, of which there are more of these kid than go to Catholic schools. This can be done by living examples of those who teach and don’t teach and by their fellow students, especially those who teach Christian doctrine, such as those in religious education programs. The bishops dance around the separation of Church and state, and the Church encourages education officials to allow religious instruction in schools.
