Catechetical instruction is a very important component that helps young Christians and adult converts to understand doctrines in the Catholic Church, including among others liturgy, prayers, and morality. It also prepares children and adult converts for first communion and confirmation sacraments.
Your Excellency, I have fairly followed the arguments for those against opening of schools. Their main argument is that the school environment is well suited to spread disease since students are often packed in small classrooms and for boarding schools in dormitories. Physical distancing guidelines are therefore impossible to implement and won’t work for the youngest children. In turn these children will spread it to the rest of the community.
