In the Bible, the book of Genesis recounts creation, at a certain point God says: ‘...it is not good that man should be alone...’ (Gen 2:18), referring directly to the creation of woman, but surely there the Creator also foresaw the need for the family and other social circles necessary for man's proper intellectual and spiritual development. This characteristic is so strong that sociology classifies man as a ‘gregarious being’, i.e. a being who needs to live in groups. It is in society that man, protected by the family, is born, develops physically, mentally and spiritually and has the opportunity to grow as a ‘human person’ with a free soul and the ability to think clearly. However, as a result of the decadence of the human soul caused by original sin, it is also in groups that vices are acquired, bad inclinations are strengthened, morals are corrupted, and the spirit of revolt is implanted day by day in empty hearts and lazy minds, as St Paul exhorted us: ...Do not be deceived: bad company corrupts good behaviour.... (1 Corinthians 15:33). In this context, the Catholic school, following in the footsteps of the Holy Mother and Teacher Church, plays an essential role, since it brings together the tripod ‘school, family and parish’, which is so necessary for the correct direction of this strong instinct, guaranteeing the success of the emotional, psychological, intellectual and supernatural education of the human being, ...teach the child the way he should go; even when he grows old, he will not depart from it (Prov 22:6). In a truly Catholic school, in addition to high-quality teaching in the natural sciences, pupils have the opportunity to socialise with children of their own age and other age groups. This is for children, young people and teenagers, satisfying the need for relationships with other people so that they can play, learn, look after each other and deal with differences, all of which, under the guidance of the teaching staff, promotes growth in virtues and curbs vices. The second support of this educational tripod is the parish, a place where, through living together with their brothers and sisters in faith, attending the sacraments and praying, they receive divine grace, which is both the only engine and the only fuel that can lead a soul to meet God and the community of the Lord's saints and angels, thus expanding the list of good examples, virtues and good role models. It is in the parish that the pupils of a Catholic school place themselves at service wherever they are called, following the example of Our Lord Jesus Christ in the temple in Jerusalem ‘and the child grew in wisdom, size and grace before God and men (Lk 2:52)’. Finally, the family, the third social group that makes up Catholic education, is the place where the theoretical concepts should be solidified. It is in the family nucleus that the parents, grandparents and uncles of Catholic pupils collaborate so that they exercise what they have learnt at school and live what they have learnt in the parish, mainly through the example of life. Experienced in this way, the Catholic school becomes a favourable environment for healthy coexistence, allowing the natural instinct for sociability to elevate man to God.
