Since parents have given children their life, they are bound by the most serious obligation to educate their offspring and therefore must be recognized as the primary and principal educators. This role in education is so important that only with difficulty can it be supplied where it is lacking.
Parents are the ones who must create a family atmosphere animated by love and respect for God and man, in which the well-rounded personal and social education of children is fostered. Hence the family is the first school of the social virtues that every society needs.
