‘Tu es Petrus et super hanc petram aedificabo ecclesiam meam et portae inferi non praevalebunt adversus eam.’ (Mt 16:18). Thus was born, discreet but indestructible, the Roman Catholic Church, by the word of its thrice Holy Founder, Our Lord Jesus Christ. In one of his letters, St Paul discusses Our Lord's spousal relationship with the Church when he exhorts women to submit to their husbands as the Church submits to Christ. And to husbands to love their wives as Christ loves the Church and gave himself for her ‘that he might sanctify and cleanse her with the washing of water by the word, that he might present her to himself a glorious Church, not having spot or wrinkle or any such thing, but that she should be holy and blameless’ (Eph 5:22-27). Being the Bridegroom of the Church and our Father, Our Lord Jesus Christ makes the Church our Mother, and entrusts her with continuing his mission as the guide and teacher of men after the time of the Advent of the Man God on Earth. According to the Instruction , the Holy Church receives from her Founder a double mission: ‘to bear children, and to educate and direct them, guiding, with maternal solicitude, the lives of individuals and peoples, whose high dignity she has always unselfishly respected and defended.’ However, in this stormy sea on which St Peter's Boat is sailing, how can we discern which is the true education that comes from the Church, and therefore from Our Lord Jesus Christ? For some trees, a glance is enough to distinguish what they are. In its Declaration Gravissimum Educationis, the Council defined education as a universal right and the responsibility of all (in its promotion and adherence), adding the school as the introducer of the cultural heritage acquired by humanity over time, and the Holy Church as the bearer of the true Christian conception of reality, as well as being in charge of educating men in the Good News of the Gospel by announcing Salvation, but also by providing all the care necessary for men as a Good Mother who nourishes and instructs her children, in her various charisms, for a single end: the Glory of God. If these definitions are not enough to distinguish this sacred tree, we can then turn to its fruits, which according to the same Declaration must be disposed (men) ‘to lead their lives according to the new man in righteousness and holiness of truth (EL 4:22-24); and thus draw closer to the perfect man, to the full age of Christ (cf. Eph 4:13) and collaborate in the increase of the Mystical Body. Furthermore, they should be aware of their vocation; they should be accustomed both to bearing witness to the hope that is in them (cf. 1 Pet 3:15) and to helping the Christian conformation of the world, whereby the natural values assumed in the integral consideration of man redeemed by Christ co-operate for the good of the whole of society.’ And how does this Holy Mother and Teacher address her children? According to Saint Augustine, in his dialogue, De Magistro, ‘he who speaks wishes to teach’ and language would have the function of teaching and calling to mind, broken down in its work as: communication, expression, discourse and that of understanding and interpretation. Whether through preaching, documents or instructions, the Holy Church speaks to her children, guiding them for two thousand years in the footsteps of her Founder. In a Catholic school, this Mother will speak by the example of the institution's authorities with an assiduous spiritual and temporal life in terms of attendance at the sacraments, prayer, meditation and reading, as well as punctuality in fulfilling their duties of state, raising them to a supernatural level, serving students and their families in the love of God. In this service to families, the good fruit, that is, Catholic education, will come from the co-operation between the two (Catholic school and family) in the intellectual, but above all, moral development of the child, providing environments and contexts that are continuous in the practice of God's Law. Finally, in the students, the greatest success and proof of true submission of a school that wishes to bear the name of Catholic will be the holiness of its students. It is therefore up to us, children of the Church, to pray and ask the Holy Spirit, through Our Lady, for docility to this maternal voice that lifts us up to Heaven.
