The Mission of Sacred Heart school is to assist but not to replace the role of the family and of the parents who are "the first teachers in the ways of the faith" (baptism ritual).
During his brief papacy, john Paul I wrote in his "Letters to Families" that "Parents are the first and most important educators of their own children, and they also possess a fundamental competence in this area; they are educators because they are parents. They share their educational mission with other individuals or institutions, such as the the Church and the State. But the mission of education must always be carried out in accordance with a proper application of the Principal of Subsidiarity... This implies the legitimacy and indeed the need of giving assistance to the parents, but finds its intrinsic and absolute limit in their revailing right and actual capabilities. The principle of subsidiarity is thus at the service of parental love, meeting the good of the family unit. For parents by themselves are not capable of satisfying every requirement of the whole process of raising children; especially in matters concerning their schooling and the entire gamut of socialization... Subsidiarity thus compliments paternal and maternal love and confirms its fundamental nature, inasmuch as all other participants in the process of education are only able to carry out their responsibilities in the name of the parents, with their consent and to a certain degree, with their authorization."
Church law has specific definitions of what constitutes a marriage and a family. The varieties of family life are described in the beautiful message from the U. S. Catholic Bishops "Follow the Way of Love." (1994)
Our role at Sacred Heart School is exclusively to aid the family and the married couple in their task of educating their children: "The matrimonial covenant, by which a man and a woman establish between themselves a partnership of the whole life and which is ordered by its nature to the good of the spouses and the procreation and education of offspring, has been raised by christ the Lord to the dignity of a sacrament between the baptized." (Canon 1055)
